Studor Engineered Products

STUDOR ENGINEERED PRODUCTS In early 1970 Sture Ericson invented Air Admittance Valves (AAVs). Born from the need to address and solve a problem with the conventional open pipe venting design, the idea grew to encompass a variety of AAVs for different applications and beyond. Today STUDOR is the world recognized leader in innovative DWV venting products and designs. Greater efficiency, significant savings, unmatched quality and unsurpassed experience make STUDOR products the #1 choice in the world. Currently in the US other manufacturers offer a limited range of AAVs, but it was STUDOR who worked with ASSE to create the standard for these valves. It was (and still is) STUDOR who worked with the Codes and Code officials to educate, gain approval and promote the understanding of the benefits associated with AAVs and it is STUDOR who continues to hold and test its products to much higher standards than even of those of ASSE (e.g. 100% of STUDOR sealing diaphrams are subject to 200% testing; STUDOR tests cycle life at 1.5 million cycles, a 600% increase over ASSE requirements). Because of STUDOR’s much greater experience and exposure to a variety of different applications, both at home and abroad, we have been able to identify unique conditions present in commercial and industrial applications not found in the residential frame. Further analysis revealed that standard AAVs did not represent the ideal products for such conditions. The clear solution was to create a new family of products specifically designed for the most demanding commercial and industrial applications. But creating only the products would not suffice; specific support literature would have to be created as well as a dedicated organization of specially trained people. Born from the very same pioneering spirit that made STUDOR the world leader in AAVs was thus the new STUDOR ENGINEERED PRODUCTS division.

INTRODUCTION TO AIR ADMITTANCE VALVES (AAVs)

Introduction to AAVs

(dealing with negative air pr essur e) The concept of venting fixtures has been a part of the plumbing industry since its conception. Balancing the pressure inside a DWV system, in order to equalize it with ambient pressure, is essential to maintain the water seal in the fixture trap. Loss of the water seal would allow the introduction of contaminants (sewer gasses and pathogens) into the living space. Lacking the insight of modem science and the aid of modern technology, early designers devised a system comprised of a series of pipes extending to the outdoors. Although with updates and variation that very same cumbersome and often slow reacting system is still very much in use today around the world. It wasn't long however before the limitations of such a design were evident (e.g. roof penetrations and all related problems, excessive material use, space limitations, frost closure, trap loss due to high wind conditions, chimney effect into the pipe during fires, etc.) Attempts were made to find more practical and effective solutions but lack of reliability and/or the inability to maintain a healthy and sanitary environment doomed most of these efforts. All that changed when Sture Ericson introduced the first Air Admittance Valve. Studor Air Admittance Valves were the first devices, offering longevity, reliability and maintaining proper sanitation, to function in place of and better than open pipe vent systems. STUDOR’s ingenious design utilizes a reverse lift sealing mechanism (membrane or ball) which opens when even minimal vacuum conditions are present inside the system and closes (due to gravity) when external and internal pressures are equalized. With the OPEN and CLOSE functions controlled entirely by pressure changes in the system and gravity, STUDOR AAVs have absolutely no springs (that can lose memory), no gears (to jam or wear) and no stress components or dynamic seals (to fail). Additionally any positive pressure, like sewer gasses trying to escape, causes the valve to seal even tighter. The r esult is a valve which far exceeds the life of the system it ser vices and maintains pr oper sanitation. But besides working flawlessly, representing signficant savings (by eliminating unnecessary vent piping and roof penetrations) and being the best solution for difficult to vent fixtures, STUDOR AAVs bring to a DWV system perhaps the most important of all features: greater ef ficiency. Because AAVs are either at or very near the Point of Need (PON) for air, and thanks to their exceptional reaction times, a system utilizing STUDOR AAVs is capable of balancing its internal pressure much more efficiently, without trap movement/depletion. This is particularly true in large commercial applications where the air needed to balance the system after each occurrence is drawn from far away points and thus require substantial time to reach the PON.

Introduction to the P.A.P.A.

INTRODUCTION TO THE POSITIVE AIR PRESSURE ATTENTUATOR (PAPA) (dealing with positive air transients) We have seen how STUDOR AAVs are the technically preferable and most cost effective way of dealing with negative air pressure in a DWV system. We have also noted however how positive air pressure in the system will cause the valve to seal even tighter. This means that positive pressure in the system must be dealt with separately. There are essentially three different types of positive pressure conditions in a DWV system: Positive pr essur e fr om the main sewer (or septic tank) Although positive pressure from the sewer or a septic tank is not a condition generated within your own system, it can certainly affect it in negative ways. For this reason it is important to have at least one open pipe vent per building system. The drawings below show two different layouts for a fourbuilding complex. In the first example (fig. 1) the four buildings only have one tie-in (thus requiring only one open vent) while the second example (fig. 2) shows four separate tie-ins (thus requiring one open vent per building). Common sense dictates that the stack closer to the sewer tie-in should be the one to open atmosphere so the positive pressure can be relieved before it has much of a chance of entering the building's DWV system and unsettling its air balance.

Fig. 1

Fig. 2

Positive pr essur e generated by a blockage or belly in the pipe This is clearly a condition requiring attention. Unlike with other kinds of positive pressure there are no devices or designs to address this problem. It's a failure of the system and it must be fixed. It is however important to understand how AAVs and a system utilizing AAVs is effected by such a condition. The first thing is to make sure the AAVs used are ASSE compliant and NSF certified. Among other things this will guarantee that the valve will be able to withstand up to 30" of water column. Such products can be installed without concerns under the flood rim level since even in the presence of positive pressure created by a blockage the valve(s) will not leak. Non third-party certified valves however may not be able to handle the pressure generated by a blockage and should not be used.

4

Being able to handle the positive pressure is certainly a plus but the nature of the valve is such that positive pressure will aid the closing function making the shutter seal even tighter. This works very well in the presence of

sewer gases (preventing their escape into the living space) when the downstream line is clear but does effect the system in a negative way in the presence of a blockage. Positive pressure building at the valve will prevent it from opening thus preventing sewer gases from entering the building.

Introduction to the P.A.P.A.

If we consider however that the blockage is a problem that must be fixed, a poorly draining fixture in a system utilizing AAVs acts as an early warning sign of a drainage problem allowing the user to address it in a timely fashion (Fig. 3). Positive pressur e cr eated by an Hydraulic Jump Finally there is the positive pressure created at the bottom of the stack (usually) in multi-story buildings. This pressure (we will refer to it as positive transient) was believed to be the result of the hydraulic jump. Recent studies however have revealed a different scenario. After free falling for 27 feet, the discharged flow reaches terminal velocity (speed of terminal velocity will vary depending on flow makeup). Once terminal velocity is reached the liquid begins its characteristic swirling effect. The resulting funnel-like motion causes the liquid to attach itself to the ID of the pipe while air is dragged in the center. At the bottom of the stack the piping system makes the transition from vertical to horizontal through a sweep. As the flow goes through the sweep, centrifugal forces generated by the swirling action keep the fluid attached to its ID, much the same way it did while falling through the vertical stack. Towards the end of the sweep however the gravitational pull exceeds the centrifugal force and the fluid coating the inside of the sweep and upper half of the horizontal pipe falls to the bottom of the pipe forming a curtain of water. It is this curtain that the trapped air hits and bounces off creating the positive transient (Fig. 4).

Fig. 3

It is important at this point to define the characteristics of positive transients. This is a low pressure wave with a volume usually not much greater than 1/2 gallon. It is impor tant to notice though that this small air vol ume is sonic, traveling at the speed of sound (appr ox. 1056 ft/sec). If unchecked and allowed to remain in the DWV system, this fast moving wave will wreak havoc in the system creating trap movement, bubblethrough, depletion or even loss of the water seal. Studies conducted at Heriot-Watt University have shown that under real-life conditions (random and sometimes overlapping usage of the system) a positive transient can reverberate in a system for up to three days before its strength is dissipated.

Fig. 4

In addition, the interaction of a positive transient with a negative pressure (created by a subsequent discharge) may in fact lead to seemingly unrelated conditions (e.g. self-siphoning) or produce expected conditions but in unexpected areas of the system. Over the years the industry has relied on either designing costly and lowefficiency dedicated passages (relief vents) for positive transients or complicated, expensive and extremely limiting devices (aerator and de-aerator fittings) in order to prevent any discharge to ever reaching terminal velocity, no matter how tall the building is. As it was in the case of Air Admittance Valves, STUDOR was first to research and bring to market a simple yet ingenious device which efficiently and cost-effectively removes the threat of positive transients. Christened P.A.P.A. (Positive Air Pressure Attenuator) the device acts like a water-hammer arrestor but for air. Unlike most water-hammer arrestors though, the P.A.P.A. device does not rely on compressed gas or springs for its operation. Naturally occurring conditions (positive pressure) are all that's

needed to make the P.A.P.A. work. For these reasons the P.A.P.A. is a nonmaintenance item guaranteed to last as long as the DWV system it services.

Horizontal Branch

How it works When the flow from a discharge (and following vacuum) goes by the branch-off fitting, the specially designed bladder inside the P.A.P.A. is primed. After the air trapped by the flow bounces off the water curtain and the positive transient is created, it begins its journey upward through the system. As the transient passes by the branch-off fitting some of it follows the alternative route and finds its way into the P.A.P.A. At the very moment that the bladder begins to expand a differential pressure is created at the branch-off point. This immediately makes the branch the path of least resistance (much like a short in an electrical loop) causing the vast majority of the transient to enter the P.A.P.A. The inflating bladder quickly (0.2 seconds) absorbs the energy of the transient thus reducing its speed to a harmless 40 ft/sec. The small volume of air is then released back into the system with no consequence. Wher e it is installed The P.A.P.A. is connected to a fitting branching off the vertical stack. Location and size of the branch-off fitting are identical to what would be used to install a relief vent (Fig. 5).

PRODUCTS FUNCTION

Fig. 5

Although the use of Air Admittance Valves provides a remarkable number of benefits to a DWV system (savings, less fire propagation concerns, greater fire protection, quicker balancing, etc.) it is important to understand that Air Admittance Valves have one and only one primary function: protecting the water trap seal. The exact same statement applies to a positive air pressure attenuator. Whether it is vacuum (that can induce self-siphoning) or positive transients that can slowly deplete or even blow the water trap, venting of modern buildings with their greater size, complexity, capacity and requirements greatly benefit from the use of such advanced venting products. Research has shown that modern living (huge concentration of population and world-wide travel) is constantly increasing the potential for the transmission of dangerous pathogens. Outbreaks have been shown to travel and spread through what was previously considered adequate DWV systems. Greater demands on DWV system is becoming simply too taxing for the old style designs. In addition, the tremendous diversification of plumbing installations requires products capable of providing features that far exceed the simple DFUs requirements. Special chemical, mechanical and thermal properties are today a must for large sports facilities, labs and industrial applications (just to name a few). The function doesn't change; what must change is the ability of the product to provide such function in a wide variety of operating environments and conditions. Available today are dedicated venting products manufactured from highstrength or high chemical-resistant materials, so that the water trap seal can be efficiently, effectively and inexpensively protected in a large capacity stadium, the world’s tallest buildings or an advanced chemical lab.

STANDARDS & LISTINGS AIR ADMITTANCE VALVES Standards are the industry's benchmark for any given product. A standard will identify the minimum performance criteria of a product. Being the inventor of the Air Admittance Valve’s exclusive technology, STUDOR was also instrumental, working closely with ASSE, in the development of today's applicable standards. All STUDOR Air Admittance Valves conform to the following standards: ANSI/ASSE 1051 (2002 revision) Single Fixture and Branch-Type AAVs ANSI/ASSE 1050 (2002 revision) Stack-Type AAVs ASSE Seal of Approval NSF Standard 14 (Plastic Pipe, Fittings and Components)

It is important to note that all STUDOR valves not only meet all but also exceed one or more of the above parameters. At 1,500,000 cycles all our valves far exceed the cycle life testing and some (like the Chem-Vent) undergo a much more stringent temperature test (8 hrs @210F) because of the potential of exothermic reaction in acid waste systems. Product listings are also a fundamental part of a product makeup. Without listing there would be no independent third party certification that a given product actually conforms to the relevant standard(s), All STUDOR Air Admittance Valves are listed with and certified by one or more of the following • ASSE • IAPMO • NES

Codes

turer’s installation instructions do not conform to minimum provisions of this code, the provisions of this code shall apply. 303.3 Plastic pipe, fittings and components. All plastic pipe, fittings and components shall be third-party certified as conforming to NSF 14.

2003 UNIFORM PLUMBING CODE (UPC) The UPC includes a provision which allows the use of alternate materials and methods such as STUDOR Air Admittance Valves when proven to be in compliance to section 301.2 — Alternative Materials and Methods. (See below) 301.2 Alter nate Materials and Methods 301.2.1 Intent. The provisions of this Code are not intended to prevent the use of any alternate material or method of construction provided any such alternate has been first approved and its use authorized by the Administrative Authority. However, the exercise of this discretionary approval by the Administrative Authority shall have no effect beyond the jurisdictional boundaries of said Administrative Authority. Any alternate material or method of construction so approved shall not be considered as conforming to the requirements and / or intent of this Code for any purpose other than installation or use within the jurisdiction granting the exception. 301.2.2 Compliance. The Administrative Authority may approve any such alternate provided that the Administrative Authority finds that the proposed design is satisfactory and complies with the intent of this Code and the material offered is for the purpose intended, at least the equivalent of that prescribed in this Code, in quality, strength, effectiveness, durability, and safety or that the methods of installation proposed conform to other acceptable nationally recognized plumbing standards. 301.2.3 Requir ements. The Administrative Authority shall require that sufficient evidence or proof be submitted to substantiate any claims that may be made regarding the sufficiency of any proposed material or type of construction. 301.2.4 Testing. When there is insufficient evidence to substantiate claims for alternates, the Administrative Authority may require tests, as proof of compliance, to be made by an approved testing agency at the expense of the applicant. 301.2.4.1 Tests shall be made in accordance with approved standards, but in the absence of such standards, the Administrative Authority shall specify the test procedure. 301.2.4.2 The Administrative Authority may require tests to be made or repeated if, at any time, there is reason to believe that any material or device no longer conforms to the requirements on which its approval was based." Studor has proven equivalency throughout the United States.

NATIONAL STANDARD PUMBING CODE (NSPC) The 2005 NCPC code will include AAVs in one of its appendixes. Use of AAVs will be allowed in plumbing systems provided that the system is approved by the authority having jurisdiction. Final code considerations It must be noted that even in the IPC, where AAVs are specifically approved, it is stated that Air admittance valves shall not be installed in non-neutralized special waste systems as described in Chapter 8. Valves shall not be located in spaces unitized as supply or return air plenums. These limitations, reasonable and appropriate, at the time the latest code revisions were written do not take into account the latest products from Studor Engineer ed Systems.

Only STUDOR CHEM-VENT is designed and manufactured for use in chemical/acid waste systems and only the TEC-VENT complies with the UL2043 discrete products standard for use in the supply and return air plenum. In such applications the system must be designed by a design professional and approved by the local administrative authorities.

DESIGN DATA When Designing Drainage Waste & Vent Systems (DWV) the one thing common to all system types is to limit pressure fluctuations within the system to within plus or minus one inch of water column to prevent loss of the trap seal. If the trap seal is lost, sewer gas can enter the building leaving a foul odor and pathogens can enter the living space. Manning Formula Manning, an Irish Engineer, derived a formula in 1890 for computing flow. His formula is still widely used today particularly in flow calculation of drainage systems. v = 1.486 X R2/3 X S1/2 n where

V = velocity of flow in feet per second, fps n = a coefficient representing roughness of pipe surface, degree of fouling and pipe diameter R = hydraulic radius (hydraulic mean depth of flow) in feet, ft. S = hydraulic slope of surface of flow in feet per foot, ft/ft.

The quantity rate of flow is equal to the cross-sectional area of flow times the velocity of flow. This can be expressed as: Q = AV where

Q = quantity rate of flow in cubic feet per second, cfs A = crosssectional area of flow in square feet, sq. ft V = velocity of flow, fps

DRAINAGE FIXTURE UNITS (DFU) Drainage Fixture Unit is a value that is directly related to the sizing and selection of both your drainage piping and your Air Admittance Valves. Specifically when it comes to selecting the right AAVs products such as Studor TEC-VENT offer a capacity range which can vary substantially (e.g. from 1 DFUs to 160 DFUs). It is important to notice that this capacity range is not at all a function of the valve size but rather of the size of the branch serviced by the valve. This observation is fundamental in understanding that the air volume restriction in a DWV system utilizing AAV is not posed by the valve but rather by the pipe. With the exception of the largest pipe size usable with the valve (in the TEC-VENT case that would be 4”) the valve is in fact capable of admitting a much greater volume of air than even the system can. Considering that the vast majority of applications call for use of AAVs on 11/2” or 2” lines it should be unequivocally understood that Air Admittance valve do not represent in the least a restriction to the air flow and thus the balancing of the system's pressure. This, combined with their proximity to the PON is what makes an AAV venting system much more responsive than open pipe venting.

Size and length of the stack and branches are identical in both systems which are operating at approx. 75% capacity as shown below in Fig. (c). The data focuses on the water retention of that trap which is mostly affected by negative and positive pressure in the system. It also shows the movement and volume of the air being introduced into and expelled out of the system (system balancing) as a function of the discharge time

COMPARATIVE DATA

OPEN PIPE VENT SYSTEM All the data shown in this chapter was developed in a comprehensive study done by Prof. Swaffield PhD and Heriot-Watt University. Prof. Swaffield is the head of the Drainage Research Group at Heriot-Watt, is a regular contributor to the Plumbing Engineering magazine, sits on the World Plumbing Council and was the key note speaker at the IAPMO sponsored SARS conference in Los Angeles. The study's reference number is EH14 4AS. The entire study is 1200 pages long and goes well beyond the scope of this manual. Should there be however further interest in the study, please contact your local STUDOR representative to arrange for a full presentation Both fig. (d) and (e) show that negative and positive pressure created in an operational system (under above described conditions) will leave the most exposed trap (lower branch) with little more than 0.5” of water, well under the minimum code requirement. Such a depletion of a trap can have consequences beyond code non-compliance. Dry traps, commonly thought to be caused by lack of use, are in fact seldom attributable to simple evaporation alone. But when evaporation is combined with a depletion such as the one shown here, loss of un-replenished traps quickly becomes inevitable

Fig.(f) and (g) show that, as to be expected, the volume of air expelled from the system (solid black curve fig. f, dotted curve fig. g) is replaced in equal measure (dotted curve fig. f, solid black curve fig. g). Two things should be noticed however: 1. After 5 seconds there is no more liquid flowing through the pipe (0 CPM ) (Fig. c) 2. 5 seconds after the end of the flow (both under + and - pressure conditions) the system is still moving air (neither curve has reached 0 CFM)

COMPARATIVE DATA

The significance of this is that the air pressure in the system is not yet balanced and the system continues to 'work' well after the end of the flow. With just one (remote) inlet for the air the system is taxed beyond its limits and is constantly playing catch-up with itself. In addition, the spikes in the dash curves of fig. (g) indicate bubbling through of the bottom trap. Previously regarded as a nuisance, it has now been proven that bubbles escaping a water seal can in fact represent a hazardous condition due to the potential of pathogens being carried into the living space by the bubble themselves.

S.T.S. (P.A.P.A./AAVs SYSTEM) By comparison a system operating under the same exact conditions but incorporating P.A.P.A.s and AAVs will react very differently. Water retention (fig. h) of the bottom trap is substantially greater (almost by a factor of 3). Also much improved is the system air pressure balancing as shown in fig (i); more specifically: 1. Air displacement (gray dotted curve). At 6 seconds (1 second after the end of the flow) the volume of the air being displaced goes to 0, between 6 and 9 seconds there is some minor additional activity primarily as a reaction to the small amount of air released into the system by the P.A.P.A. after having absorbed the energy of the positive transient, at 9 seconds there is no more air being displaced. 2. Air intake (solid black and solid gray curves). The combined air volume intake of the stack AAV (solid black curve) and the branch AAVs (solid gray curve) quickly and more homogeneously replenish the system with the same volume of air displaced by the flow. Both stack and branch AAVs stop admitting air at approx. 7 seconds and remain close after that. 3. Positive pressure (black dotted curve). The P.A.P.A.s quickly reacts to the positive pressure between 5 and 6 seconds, briefly fluctuate and then rests at 9 seconds.

20

This graph depicts a much quieter system where events are dealt with efficiently and effectively. A system where the load is spread over several different devices strategically located so as to react much more quickly to the system's needs. It also shows no effect to the critical lower trap and a very clear end to all system's activities shortly after the discharged waste has been evacuated from the DWV piping system.

AAVs SYSTEM DESIGNS

Design Data AAVs

There are many designs that can utilize Studor's Air Admittance Valves. Various layouts of acceptable designs are shown in the following diagrams. These isometric drawings are intended to show some of the acceptable designs; however several additional designs are also acceptable. The size of the Studor Air Admittance Valve is determined based on the pipe size required for the vent. Vent pipe size must be, at a minimum, one half the size of the required drainage pipe.

Table A

P.A.P.A. SYSTEM DESIGN & ENGINEERING DATA

Design Data - P.A.P.A.

There are several issues to be recognized as the drainage and vent system responds to transient propagation: • the pressure profile is constantly changing; • the area of risk to trap water seals is dynamic and constantly changing; • the volume of extra air in the system will depend on airflow rate, closure times of blockages and the AAVs' pipe period of the system – all of which are not constant. To deal with these uncertainties, the P.A.P.A. units should be distributed throughout the system. The following is a guideline of how many P.A.P.A. units would be required per stack. This would vary depending on the plumbing design. In the case of a restaurant situated on the 30th floor of a building, the peak frequency would be higher due to the peak flow demand. Therefore, it would be recommended that two P.A.P.A. units in series be installed below this floor (Fig. 15). In the case of low flow discharge to stacks, the use of one P.A.P.A. unit at the base may serve up to 8 floors.

Design data - P.A.P.A.

Fig. 16

With the P.A.P.A. units installed throughout the system, the protection against positive transients would never be more than eight floors away. Therefore the transient is dealt with before it can affect the whole system. It is essential to recognize that to be effective, a pressure transient attenuator must be placed between the source of the transient and the appliance to be protected. The P.A.P.A. device is a maintenance free product; as such it does not need to be accessible. Fluids and suds entering the device will not restrict the device's ability to neutralize the negative effects of pressure transients nor will they compromise the life expectancy of the unit.

Fig. 17

Suds vent lines can be accommodated in a system utilizing the P.A.P.A. device as shown in fig. 17 (drawing depicts an in-series installation with MAXI-VENT). Note: The P.A.P.A. does not solve the problem of a slow buildup of pressure, a sustained positive pressure originating from deposits blocking the pipes, the blockage of a public sewer, an overloaded septic tank, etc. This is an inherent problem that must be resolved with or without the installation of P.A.P.A. devices or AAVs.

STUDOR offers a full planning ser vice for designs of drainage venting systems incorporating the STUDOR products.

PRODUCTS

Products – TEC-VENT

TEC-VENT The TEC-VENT is the only air admittance valve manufactured using Polycarbonate (Lexan®) resin. The elevated tensile strength of the material (both at high and low temperatures) makes this product ideally suited for extremely demanding and rough construction sites. UV inhibitors have been added to the resin so that it can be exposed to sun light (outdoor use) without compromising life expectancy. The Oxygen index of the material combined with its flame and smoke properties allowed the TEC-VENT to be classified in accordance with UL 2043 for installation in the supply and return air plenum (must be part of an engineered system). This particular UL classification was developed specifically for discr ete products and their use in the return air plenum. Whether used in the air plenum or not the TEC-VENT is currently the only air admittance valve featuring a material which is both flame retardant (self extinguishing) and possesses advanced flame properties. Combined with the inherent reduction of fire stopping applications of any air admittance design, these features make the TEC-VENT the ideal valve for any public constructions such as schools, hospitals, hotels, airport terminals and many others.

CHEM-VENT

Producst - CHEM-VENT

Studor CHEM-VENT is designed specifically for use in acid and chemical waste systems. Material of construction (of all components) and valve design have been carefully researched and developed to specifically meet all the demanding requirements in such systems. The FR-PP resin used for the valve is the very same material that over the last 20 years dominated the acid waste market due to its outstanding chemical resistance as well as high temperature rating. An EPDM seat was also selected for its chemical resistance properties. In addition to the choice of materials Studor Chem-Vent has been subjected to much more stringent testing to take into account the much greater temperature developed by exothermic reactions in acid waste systems. The extended leg Sch 40 connection allows direct mount on any acid waste sytems (MJ or fusion) as well as CPVC, glass or Duriron systems with an adapter.

MAXI-FILTRA

PRODUCTS - MAXI-FILTRA

The MAXI-FILTRA operates as a two-way vent, which filters air in both directions. Its replaceable active carbon filter is designed to eliminate bad orders produced by the plumbing drainage system. The MAXIFILTRA is for outdoor use only, particularly for use with septic systems, but can also be installed on existing open vent pipes and in systems in which air admittance valves (AAVs) are installed. The MAXI-FILTRA, as part of the complete STUDOR System® eliminates sewer gases from entering buildings or polluting the surrounding areas. It can also be easily retro-fitted into an existing plumbing system.

IN-WALL ACCESS BOX AND PANEL

Products - Recess Box

STUDOR offers a recess box and panel ideally suited for in-wall installation of its Air Admittance Valves. Whether on individual fixtures or circuit installations it may be impractical or not possible to conceal the valve in an existing cabinet. In such installations and when concealment is desirable STUDOR in-wall valve box provides a safe as well as esthetically pleasing solution while providing code required accessibility to the valve. The box can also be used as the termination point for an open pipe side wall vent as an alternative to venting through the roof.

INSTALLING STUDOR AAVs

Installation

1. STUDOR AAVs must be located a minimum of four (4”) inches above the weir of the fixture trap. 2. STUDOR AAVs shall be accessible should service, repair or replacement be required. For in wall installation use STUDOR box/grill combination. 3. STUDOR AAVs location must allow for adequate air to enter the valve. When located in a wall space or attic space lacking ventilation openings, openings shall be provided. Locating the valve in a sink or vanity cabinet is acceptable. 4. STUDOR AAVs must be installed in the vertical, upright position. A maximum deviation (in either direction) from plum of 15° is allowed. 5. The vent shall connect to the drain vertically to maintain an unobstructed opening in the piping to the STUDOR AAVs. 6. A minimum of one vent shall extend outdoors to the open air for each building drainage system. Such open air vent should be located as close as possible to the connection between the building drain and building sewer. 7. The MAXI-VENT must be installed six (6”) inches above the highest flood level rim of the fixtures being vented in stack applications. 8. STUDOR AAVs installed in attic area must be located a minimum of six (6”) inches above the ceiling insulation. 9. The use of TEC-VENT in return air plenums or CHEM-VENT in acid/chemical waste applications shall be allowed only in engineered drainage systems designed by a design professional. 10. The maximum height of drainage stack being vented by a MAXI-VENT must not exceed six (6) branch intervals. 11. When a horizontal branch connects to a stack more than four (4) branch intervals from the top of the stack. A relief vent shall be provided. The relief vent must be located between the connection of the branch to the stack and the first fixture connecting to the branch. The relief vent may also serve as a vent for the fixture. The relief vent must connect to the vent stack, stack vent or extend outdoors to the open air. 12. Only Teflon® tape can be used on the valves' threads. Use of primer, solvent cement or pipe dope will void STUDOR warranty.

TEC-VENT / CHEM-VENT / MAXI-VENT / MINI-VENT / REDI-VENT must be installed at finish, after the system rough-in and pressure test.

PRESSURE ATTENUATOR

PRESSURE ATTENUATOR

Fig. 18

THE P.A.P.A. MUST BE INSTALLED AFTER THE SYSTEM’S PRESSURE TEST AND MUST BE ACCESSIBLE

1. The P.A.P.A. can be connected directly to the branching elbow by slipping its synthetic rubber connector (provided) onto the fitting 2 1/2” spigot or push-fitted into a 4” socket. Alternatively the unit can be connected to the pipe by means of a Fernco coupling 2. The P.A.P.A. can be installed as a stand-alone unit (without the Maxivent). This configuration is allowed only when no additional air admittance in the system is required. 3. The P.A.P.A. unit can be mounted vertically, connecting to the stack by means of a WYE 90° bend or two (2) 45° bends. These mounting solutions are mandatory when the P.A.P.A. is used in conjunction with a MAXI-VENT. 4. When mounted vertically (parallel to the waste stack) the P.A.P.A. device should be independently supported by an anchor connected to its housing (Fig. 16). The anchor's metal hoop around the P.A.P.A. housing should allow for expansion and contraction and be rubber lined to prevent damage. 5. When mounted horizontally or at any angle between 0° and 90°, the P.A.P.A. device should be supported or anchored. The portion of the support or anchor in contact with the device housing should allow for expansion and contraction and be rubber lined to prevent damage. 6. When horizontally mounting the P.A.P.A. device, it is advisable to maintain a minimum of a few degrees of slope so as to induce self draining. 7. When configured without a MAXI-VENT, the P.A.P.A. unit may be installed horizontally 8. Up to a maximum of four (4) P.A.P.A. units can be joined in series to provide additional capacity and protection. This solution is recommended at the base of the stack or at any point in applications where heavy use is expected. 9. It is recommended that the P.A.P.A. units be installed with a MAXI-VENT on top. The cap of the P.A.P.A. should be removed and the MAXI-VENT pushed onto the unit using the connector. This will turn the P.A.P.A. unit into a device capable of protecting against both positive and negative transients. Localized venting will limit the magnitude of the final pressure transient by bringing the air intake closer to the event.
