| Water Pressure | June 16, 2010 @ 9:27am | I have received a number of calls this year regarding water drips and leaks from faucets. As originally plumbed, houses in LaVista Park would not have had Pressure Reductions Valves (PRV's) installed. My house being one of them, I have also experienced leakage at my water heater Pressure and Temperature Valve (P&T) and noticed that closed faucets will drip a few drops of water for a minute or 2 after use.
I'm not sure of the cause but it appears that county water pressure has increased to our area. Unconfirmed, maybe a sales pitch, but one LVPCA homeowner was told by plumber that house pressure was at 130psi.
PRV's should be set at 70psi or less to maintain faucet seals, obviously if you have one in your plumbing (usually just after whole house shut off valve), you can adjust it or replace it if damaged. If you have the above problems, you might consider adding a PRV (not easy if you have rusty original galvanized piping). Retrofit is not a code requirement, but would help conserve water and save your fixtures. Replacing seals, fixture, or P&T will not solve high pressure leak problem, as least not for long.
