I have a swing check valve that is between the water meter and the main ball valve. I have a water pressure booster and noticed that when no faucet is open in the house the pressure drops slowly, making it hard to maintain water pressure. I've tested by turning on the pressure booster with 4 gallon pressure tank and closing the main ball valve. The water pressure held. As soon as I opened the main ball valve the pressure started to drop. I assume it is sending back to my neighbors.
I opened the top nut on the swing check valve and tried cleaning with a toothbrush what I could. The valve does not seem to be corroded since it had been installed 2 years ago and moved pretty freely. After closing everything back up, it's the same. The pressure gradually starts lowering.
My utility water pressure is at 10 PSI and they won't do anything to increase it.
I got the guys that installed it to come back and verify. They managed to take the clapper out and cleaned it, but still was loosing pressure. They told me that I would need to get a 3/4" spring check valve, but in the process would need to get into the concrete to replace. They told me that it is probably due to the hard water here.
Since I don't want to have to replace keep replacing check valves and keep destroying the concrete floor every 2 years what type of check valve do you guys recommend?
