Hello all, I am so happy I found this site. I hope to be able to contribute some valuable input. I have a problem that I’m sure someone can offer an opinion on. I have very low water pressure. When I open a faucet pressure is good for approximately 2-3 seconds and drops dramatically (at least 75%). It affects the entire house, all faucets etc... Here are my details:
1. My water comes from the city supply.
2. I live on a hill, up from the main supply line.
3. My neighbors do not have the same problem.
4. I have cleaned ALL aerators/screens/cartridges and valves at the faucets.
5. I have a pressure regulator, ½” in/out.
6. My copper lines are all ½”, all original as far as I can tell.
7. My supply from the street is ¾”.
8. My house is about 50 yrs old.
9. I have not made any major changes to the plumbing system.
10. I do not have a pressure tank anywhere in the system.
11. This has been a problem from the day we moved in. 1 yr ago.
12. I have tested the pressure with a gauge (110psi all faucets closed, 20psi one faucet open). I have adjusted the pressure regulator without success.
I went to a local hardware store and was advised to remove the pressure regulator all together. He said he does not think they are needed in our area. I don’t have a warm and fuzzy feeling about that. I figure it was there for a reason. Besides, my neighbors still have theirs. So that’s what I got. Any input would be greatly appreciated.
