I just thought I would post this to see if anyone else had run into this problem. I noticed the red dial indicator continuously turning on my water meter , indicating water running even when no faucet or other device was on. Points to a leak. I checked the water pressure and saw it to be 100 psi when the pressure reducing valve is set for 55 psi. This tells me the PRV is bad, so I thought that would be where the leak is. The PRV is 3 feet from the water meter underground. I dug up the PRV only to see it dry. Still, since it is not regulating properly, I replace it. To my surprise, even though the old PRV was not leaking, putting in the new valve stopped the indicator on the meter from turning. To sum it up, the defect in the PRV was somehow causing the water meter to register water running when it was not. This was a Neptune water meter. This amounted to approx. 1000 to 2000 gal. per month on my bill. While not that much money, I still wanted the problem corrected.
