Hello just joined the forum and looking for help in finding my PRV valve. First let me start with the details I live in a 30 year old 1600 sq/ft raised ranch on a concrete slab, copper plumbing inside finished basement, City of Grayson Georgia water. Lived in the house 11 years the problem started when the city hired a contractor to replace the lines from the main to the meter. The day after they replaced the line I lost water volume not pressure IE turn a faucet on OK, turn two on not OK, flush toilet and faucets slow to a dismal trickle.
I had the city water dept come and check on things. Pressure before meter 150 psi flow 30 gal/min, test pressure at house 60 psi flow 3.5 gal/min. Theory the contractor got sediment in the line and it plugged the screen on the PRV valve. Fine only with one exception I cannot find the valve.
I have never seen a water shutoff nor a PRV valve in the house. I have checked the basics nothing at the water tank I knew before I even looked because I changed the tank the first year I lived there. When I changed the tank I had to shut the water off at the curb.
I traced the cold line back ten feet running parallel with the cellar hall but instead of turning ninety and going towards the front of the house it goes towards the back into the back laundry room down the wall and I believe into and then under the slab only to run I suppose towards the front of the house.
I checked down the laundry room wall with a Ridgid, Seesnake optical camera no sign of the valve. I dug up after the meter box no sign of the valve within 5 feet of the box. The line running from the meter to the house is 1" PVC, all the household plumbing is copper.
I have checked the walls with metal detectors, stethoscopes, Seesnake optical devices but have come up empty handed (other than a drywall spatchula to patch the holes).
I do not know where to go next, my thought is to dig the line up from the meter box to the house. If I do not find anything, then shut the water off at the meter and cut the line. Run a fish tape inside until it stops, at least I will know I either hit a elbow or the PRV valve.
The only other thing I can think of is trying to back-flush the entire water system and flush out any debris trapped at the inlet screen to the PRV valve. Any other suggestions are more than welcome. It is very, very, aggravating when you had great water pressure/volume, then along comes a bunch of yoyo's and its gone as well as them and you have to deal with it. Thanks in advance, Sincerely Vic
