3/4Inch Water Meter Brass(NO Plastic)WM34CC ,With Couplings HEAVY DUTY

Description

INSTALLATION
New Service Lines:
New service lines should be flushed prior to installing water meters. A spool piece matching the length of the meter or an old meter with measuring element removed should be installed in place of the installed meter so the lines can be flushed.
Electrical Grounded Pipe Systems:
"AWWA opposes the grounding of electrical systems to pipe systems conveying drinking water to a customer's premises". However, it is recognized that many pipe systems continue to be used as a grounding electrode system.
Section 260-81 (A) of the National Electric Code (NEC) requires that "continuity of the grounding path or bonding connection to interior piping shall not rely on water meters." All meters should be permanently grounded strapped to prevent accidents to service workers changing maters.
Piping:
It is recommended that meters be mounted in a horizontal position, protected from freezing, damage and tampering. The line opening in which the meter is to be set should match the lay length of the meter, allowing slight additional space for coupling gaskets. The service line configuration should have straight piping, which is necessary for proper flow conditioning both upstream and downstream of the meter. The meter should not be used to straighten misaligned pipes because of the potential for damage to the meter.
Meter Installation:
To prevent cross threading at installation, set the meter between the coupling nuts with the direction of flow through the meter corresponding to the direction of flower in the system. Engage the coupling nuts to the threaded meter ends. Check to ensure that the nuts are properly aligned to avoid cross-threading damage to the threaded meter ends.
Two fiber gaskets are provided for sealing of the coupling to the meter. No pipe dope or sealants should be used on the meter end of the connection.
Put Meter in Service:
After the line has been thoroughly flushed, open the shut-off valve slowly to pressurize the service line to the meter setting. Slowly open the inlet side valve, which will fill the meter with water. Check for leaks around the meter and connections. Open the meter outlet side valve slowly to pressurize the consumer side of the system. Open a consumer faucet slowly to allow entrapped air to escape.
