Hi, I recently purchased an older home (1974) that is on county water. Since moving in, we have had fairly low pressure when using any faucet or toilet. When showering and a toilet is flushed, the pressure/flow drops to near nothing. I didn't think much of it but finally got a gauge and checked my static pressure. It was an amazing 118 psi. When I turned on any other faucet, it dropped to below 10 psi. This occurred at two different outside faucets at opposite ends of the house, one near the water line entry and the other at the far end. I checked the water meter and verified that the valve was fully on and there didn't appear to be any damage. There is a PRV on the house side of the meter. It was completely buried and I didn't see it at first because of the dirt but the adjustment screw stuck out of the dirt slightly. There appears to be 3/4" PVC leading toward the house. There is also a second PVC line split off of it I believe towards either another home site (used to have a trailer) or my barn(not sure where that line comes from). Turning this valve off does not affect my house pressure at all (I didn't check the barn). The house does sit on a hill about 25 feet above the main valve from the street. I suspect the my PRV is bad and needs replacing but just getting confirmation. ****Additional info, there are at least 7 houses on the county line along this road. We recently lost all water to these houses. It is also the primary line to a chicken processing plant, which is likely why the pressure is so high, BUT the county didn't know that we were on the plant's water line until a main break occurred recently at the plant. I was told in no uncertain terms that there were no houses on that line and my water problem could not be caused by the water outage at the plant. It came back on when the main line at the plant was repaired.
