Educate me about taking the water pressure at the water heater.
I test the outdoor faucets and/or the laundry. The highest I ever got was 173 and another at 168. Often I find 120, but that is at a faucet that is also connected to the irrigation system, where we seem to run higher water pressures here.
If there is no irrigation system, I’ll just test one faucet. If that one faucet is high, then I’ll test more.
The seller at the 173 house had disclosed that he regularly has problems with plumbing leaks at the faucets. Well, duh! And one wonders what the hec the plumbers were doing each time they put new faucets in.
