I went over and looked at a job, (where he needs a new water supply line). He has a 5/8” water meter and the supply line is ¾”, (old and rusted) galvanized line. The distance from the meter to the house is around 40 feet.
When I tested for static pressure, he was getting 92 psi. When the back yard sprinklers came on, (as I was testing for static pressure) the pressure dropped down to 12 psi. I told him that he does need a new supply line, and, (because of the 92 psi) a pressure reducing valve. The only draw back, I told him, is that if the rest of the galvanized pipe that goes into the house is also restricted, and if we do install a prv, (and dial it down to around 65 psi) he may still have really low water volume in the house. He did mention to me that he has other plumbing issues in the house, and I should have had him elaborate on what he was talking about, but didn’t. I will call him on that today.
My question is; at what point is the psi considered, “excessively high water pressure” especially, taking into consideration that the house was built in the early 60’s.
Thanks, Mike
