Cross Connection• – Arrangement of piping which allows a potable water supply to become connected to a line which contains a contaminant.

• Back-Siphonage – Reversal of normal flow direction due to a negative pressure in the supply piping.

Backpressure Backflow• – Reversal of normal flow direction due to an increase in downstream pressure.

Thermal Expansion • - Once a backflow preventer is installed a system becomes closed. After this point as the temperature rises, the water will expand. Without proper room for expansion there is an increased risk of damage to the plumbing system.Potential Results• – Leaking TCP valve or other relief valves, leaking pipes, blown joints, ruptured boilers, ruptured hot water heaters, serious burns, water dam-age, mold, mildew, water hammer, and many more symptoms may result.

Terminology Associated with Backflow Prevention

Degree of Hazard• – Potential threat to water quality of a particular cross connection or chemical.First Line of Defense• – Backflow Preventers located just prior to the contaminant source, or located at each fixture which might allow a contaminant to enter the potable water system.Containment• – Backflow Preventers located at points where public water supply and private water sup-ply are connected. This “Second Line of Defense” ensures that the public water quality is not compromised if the first line of defense is tampered with, altered, or is not adequately serviced.Cross Connection Control Program• – This is a com-bined cooperative effort between plumbing and health officials, waterworks companies, property owners, and certified testers to establish and administer guidelines for controlling cross connections and implementing means to ensure their enforcement so that the public potable water supply will be protected both in the city main and within buildings. The elements of a program define the type of protection required and responsibility for the administration and enforcement. Other elements ensure continuing education programs.

ApplicationsReduced Pressure Backflow Devices should be used

whenever the non-potable source is more of a contaminant than a pollutant. Basically, they are applied as main line protection to protect the municipal water supply, but should also be used on branch line applications where non-potable fluid would constitute a health hazard, such as boiler feed lines, commercial garbage disposal systems, industrial boilers (see typical installations below).

Where to UseReduced Pressure Zone Devices may be used on

all direct connections which may be subjected to back-pressure or back-siphonage, and where there is the possibility of contamination by the material that does constitute a potential health hazard.

Typical Installations:Main Supply Lines • Laboratory Equipment• Commercial Boilers • Waste Digesters• Cooling Towers • Car Washes• Hospital Equipment • Sewage Treatment• Processing Tanks•

Applications Double Check Valve Assemblies may be used where

the degree of hazard is low to intermediate, meaning that the non-potable source is polluted rather than contaminated. The degree of hazard is often determined by local Inspec-tion Departments and therefore such departments should be questioned in order to comply with local regulations.

Where to UseA Double Check Valve Assembly may be used as

protection of all direct connections through which foreign material might enter the potable system in concentration and which would constitute a nuisance or be aesthetically objectionable, such as air, steam, food or other material which does not constitute a health hazard.

Typical Installations:Main Supply Lines• Food Cookers• Tanks and Vats• Lawn Sprinklers• Fire Sprinkler Lines•

Dual Check Backflow

Preventers

Series #7 Dual Check Backflow Preventer - ½" thru 1¼"

Residential Protection for Public Water Supply

The # 7 Dual Check Backflow Preventer is designed for containment control programs and installation at the residential water meter or service entrance.

The Dual Check Backflow Preventer provides maxi-mum protection for the public water supply when utilized in comprehensive total containment programs. The Dual Check is designed to support the local or state plumbing code requirements for each premise served.

It is generally understood that the water purveyor has no authority to conduct plumbing inspections and that residential homes often fall into a category of non-compliance with the code, resulting in a potential health hazard for the consumer and the community water supply. Therefore, a comprehensive program to protect safe drinking water will consist of the following three major components as conditions of the agreement or contract for receiving service from the public water system.

The user must certify that his domestic water system is • in compliance with the plumbing code — The first line of defense.The user must install a Dual Check Backflow Preventer, • located at the water meter, as prescribed by the purveyor of water. — The second line of defense.In addition to providing an ample supply of qual-• ity drinking water, the supplier must also provide information to the user on prevention of inadvertent contamination or pollution of that water once it has entered the domestic water system. This is basi-cally a descriptive explanation of the local plumbing code — Education.

NOTE: Team EJP has the information which explains why it is so important to protect both the public water supply and domestic water system.

Series 7 straight line poppet type construction minimizes pressure drop and provides smooth flow characteristics. It is not adversely affected by normal line pressure surges, will not cause water hammer and operates without chatter or vibration. It can be installed horizontally or vertically. Tested and certified to meet or exceed the 1988 revision of ANSI/ASSE Standard 1024 for “Dual Check Valve Type Backflow Preventers.”

NOTES:The #7 Dual Check is 100% lead free. • See Section H for K-Horns and Pack Joint Assemblies. •

K-Horn Dual Check The #7 Dual Check Valve is attached to the outlet side

of the K-Horn meter setter and connected to the inside service pipe with a Pack Joint Assembly.

Watts “High Capacity Relief” Series 909 (RPZ)

Backflow Preventer

“Series 909 protects against back-si-phonage and backpressure with both

checks fouled.”The principle is simple, but it’s used to solve a complex

safety problem. The Series 909 is the only backflow preven-ter available that provides protection against simultaneous back-siphonage and back pressure backflows.

A patented built-in vacuum relief is designed around the air-in/water-out principle. The valve has two channels: one for air, one for water. When the relief valve opens, one channel admits air to the top of the reduced pressure zone. The other channel then drains to atmosphere. Therefore, if both check valves foul and simultaneous negative and positive backpressures develop, the relief valve will stop potential backflow by providing “high capacity” relief .

Series 909 RPZ 2½" – 10"

Series 909 RPZ ¾" – 2"

StandardsTested and certified under the following standards for re-duced pressure principle backflow preventers: ASSE No. 1013, AWWA C511-92, CSA B64.5, FCCC-HR of USC Manual 8th Edition Section 10, U.L. Classified File No. EX3185 (sizes 2½" thru 10"). Listed by IAPMO PS-31-(UPC), SBCCI (Standard Plumbing Code). Check local codes for approval of vertical installations.

Relief Valve

No. 909QT-S

Use ¾" – 2" 909s for backflow protection in both cross-connection control and containment at the service entrance. The 909 “high capacity” relief incorporates the “air-in/water-out” principle and substantially improves the relief valves discharge performance. The emergency condition of combined back-siphonage and back-pressure with both checks fouled can defeat the effectiveness of a standard RPZ backflow preventer. This device may be installed in a verticle position in accordance with ASSE 1013 standard.

909 Shown with Optional OS&Y RW Valves

2½" –10" sizes provide backflow protection for both cross-connection control and containment with their unique patented design incorporating the “air-in/water-out” prin-ciple. Normally furnished with non-rising stem (NRS) resilient wedge gate valves.

NOTE: RPZ compact assembly is now available in 4" and 6" sizes. Contact your nearest Team EJP Sales office.

IMPORTANT NOTE: Inquire with governing authorities for local installation requirements.

Thermal Expansion Solutions

FOR SAFETY…Always make sure there is a functional temperature

and pressure relief valve before you install a Backflow Preventer. This will prevent a dangerous condition, but does not prevent plumbing system damage. Most hot water heater manufacturers’ warranties become void if a Backflow Preventer is installed without a means of reliev-ing excess pressure.

Watts® Governor 80-M1

Ball Cock and Relief Valve for 80 PSI Static Pressure Code Compliance.

The unique Watts® Governor 80-M1 is a multipurpose device, anti-siphon ball cock, Backflow Preventer, thermal expansion pressure relief valve and a ball cock water closet fill valve. It allows contractors and code officials to eas-ily design a safer water system without extra plumbing for expansion tanks or auxiliary relief valves to alleviate excessive pressure from thermal expansion.

The idea is simple and revolutionary. One triple-function device offers all these capabilities:

Limits and governs the domestic water system preset • static pressure to 80 psi, as required by plumbing codes.

Protects the temperature and pressure safety relief • valve on the water heater from unnecessary relief, reserving it for its primary function.

Eliminates the need for more expensive thermal ex-• pansion tank or an auxiliary relief valve that serves the same function.

Prevents backflow from water closets, a serious • cross connection.

Features and Specifications:The Watts• ® Governor 80-M1 incorporates the simplest “full flow” ball cock principle available. It has a large, non-clogging flow way which permits quiet operation and snap-action shut-off under a wide range of flow pressures. Durable PVC and Celcon® are used in the unified construction which makes the “Watts® Governor 80” completely non-electrolytic and non-corrosive. Reliability is built in from the beginning.

The Watts• ® Governor 80-M1 meets IAPMO, ASSE and CSA requirements for anti-siphon ball cocks. All materials in contact with water are FDA approved. The relief valve is set at a standard of 80 psi to meet existing codes and is non-adjustable. However, other settings of 60, 100 and 125 psi are available with maximum operating temperatures of 140°F. Standard lengths are 10", 11½" or 12½".

You can replace an existing water closet fill valve with the Watts® Governor 80-M1. A removable

cap ring provides for easy service.

NOTE: Also available in 10" and 12½" sizes.

Restrained Joint

PVC Pressure Pipe

The Certa-Lok Yelomine piping system can provide a unique solution to many of your speciality and standard piping system needs, either temporary or permanent applica-tions. Certa-Lok Yelomine’s jointing system and physical properties allow this pipe to be used in a broad range of piping applications.

Certa-Lok Yelomine pipe offers a reusable, easy to assemble, fully self-restrained spline locked joint, virtually eliminating thrust blocking. A gasket provides a hydraulic seal while the spline securely locks the coupling to the pipe.

Certa-Lok Yelomine is manufactured from a specially formulated PVC compound which contains impact modi-fiers and UV (ultra violet) inhibitors. These modifiers and inhibitors provide a higher impact strength over an extended period of time and allow Certa-Lok Yelomine to be used in above-ground, exposed applications.

ToughnessSpecial PVC compounds used in the manufacturing

of Certa-Lok Yelomine pipe give it high tensile and impact strength. Yelomine pipe also has excellent resistance to chemicals and scale build-up and it can't corrode.

FlexibilityCerta-Lok Yelomine pipe can bend around many

obstacles, thus reducing the number of fittings required. When assembled, couplings (joints) are not affected by standard pipeline bending.

Certa-Lok™ Yelomine™ PVC Restrained Joint Pressure Pipe

SafetyCerta-Lok Yelomine pipe has the highest physical

strength available in PVC (2000 psi design stress). This means it has a longer life and is more reliable than roll grooved PVC. Yelomine pipe is self-extinguishing.

LightnessLight weight means pipe can be handled manually in

convenient 20' sections.

Abrasion and Chemical ResistanceCerta-Lok Yelomine pipe will outlast steel pipe in slurry

applications because it doesn’t rust or corrode. Its chemical resistance exceeds the requirements of ASTM D-1784 and it is not damaged by acids found in mine water.

Sustained PressureAn important property of plastic pipe is its long term

strength under pressure. This property is best expressed by a stress vs. time curve which becomes a straight line when plotted on logarithmic scales. Data for this straight line is obtained by conducting long term hydrostatic pressure tests in accordance with ASTM D-1598 and ASTM D-2937. This plot is known as the stress regression line and basically is a response to applied internal pressure over a long period of time.

The hydrostatic design basis is chosen at the 100,000 hour value (11.4 years). This minimum design stress life of 100,000 hours at 4,000 psi is modified by a safety factor of 2:1, resulting in a pipe life expectancy of over 100 years at 2,000 psi design stress. As shown in the graph below, test samples of Yelomine exceed the minimum requirement of 4,000 psi at 100,000 hours.

Impact StrengthThe PVC compounds used in Yelomine pipe greatly

exceed the impact strength of conventional Type 1 PVC. Impact strength tests are regularly made on Yelomine pipe in accordance with the requirements of ASTM standard D-2444.

Average impact values are two to four times greater than the impact resistance of conventional PVC.

Assembly and Disassembly Start — Couplings and pipe have matching grooves. Just 1. wipe them clean and apply a small amount of lubricant to rubber rings and pipe ends.

Push — Couplings slip easily onto pipe. When pipe end 2. seats against stop, grooves are automatically aligned for spline insertion.

Lock-Up — Nylon spline is pushed into aligned grooves 3. around the pipe’s circumference, securely locking pipe to coupling. Special rubber seals provide bottle-tight fit. Assembled coupling is so strong that no blocking is needed to support it.

Tear-Down — Nylon spline is pulled out and pipes 4. pulled apart. Use silicone lubricant (available through your local Team EJP sales office) if pipe is to be dis-assembled.

Non-Permanent Use Certa-Lok JointThis product offers a Teflon coated “O”-Ring, which

is blue-black in color. Non-Permanent Use Certa-Lok Yelo-mine minimizes assembly and disassembly effort required to install, remove and reinstall a system.

The Non-Permanent Use Certa-Lok joint is typically used in above-ground, exposed installations and where disassembly and reuse may be required.

Non-Permanent Use Certa-Lok joint is NOT recom-mended in buried installations or installations where the joint is subject to long-term or excessive misalignment due to external forces such as earth loads, live loads, etc.

2" through 6" sizes typically do not require lubricant for assembly due to the Teflon coating on the “O”-Rings. 8" through 16" sizes require lubricant to assemble.

PVC Pressure Pipe

NOTES: Non-Permanent and Permanent Use joints are totally interchangeable and can be mixed in the same piping system. The •only difference is the “O”-Ring gasket.If in doubt as to which system to use contact your local Team EJP sales office for assistance.•

Permanent Use Certa-Lok JointThis product is the same as Non-Permanent Use with

the exception that the “O”-Ring used, has a slightly larger cross section and is not Teflon coated. The joint assembles easily using lubricant. Disassembly can be achieved, but can be extremely difficult depending on the diameter of the pipe being used.

Permanent Use Certa-Lok joint is intended for use in buried applications, bridge, river and road crossings and all installations that would be considered permanent, as well as installations that would encounter joints being subject to long-term or excessive misalignment due to external forces such as earth loads, live loads, etc. This joint requires lubricant to assemble.
