I need to replace (or hire a plumber to replace) a section of pipe from the output side of the water meter (which is located in the house).
I picked up Rex Cauldwell's Plumbing book at the library, and he talks about a Dual Check Valve that is required by most water utility co.
I do not see a check valve in the line now, unless the long coupling shown in the photo below is a check valve.
Thanks for your advice.
Edit: On second thought; I believe the meter incorporates this device. It is only 3 years old.
Actually, from what I have found online since posting, my water meter probably has an internal check valve. Maybe I should e-mail my water utility, unless I can get the model no. from the meter and look up online.
I am going to a real plumbing supply tomorrow to pick up the connector for the meter, so I can ask about a check valve while I'm there. Those guys should know a lot more than the people who work for the big box store.
Edit: I got the spec sheet for my water meter. No mention of a check valve, so I've gotta buy one.
