A couple of weeks ago, I noticed reduced water flow. I had it checked by water company. The indicated all is fine on their side. About 8 gallons a minute, as tested through my meter. On my side I see about 4 gallons a minute. Rep told me that it could be pressure control valve. My neighbor has PCV close to meter box. So I dug around a little, but did not find valve on my side.
Q:If indeed I have one of these valves where else might it be installed?
Q:If I don’t have one of these PCV’s, what else could be the problem?
