    Water pressure at 80-85psi, do I need a PRV?

    My water softener got fried (because of a dumb mistake) and before putting in a new one I decided to install a whole house filter and bypass loop to tame the chlorine. Part of that loop includes some pressure gauges and I found that our pressure is pretty steadily 80-85psi on city water. I...

    Is my Pressure Regulating Valve bad?

    I checked my spigot outside with a pressure guage and it's showing a little under 100 PSI. The only symptom I'm noticing is some wooshing sound in lower level, basement, copper pipes when a toilet is flushed or water is running for long period. It's been like that since we moved into this house...

    So I'm installing a new prv valve. My old one had failed and I had no flow. What would be the best way to attach the prv to pvc since it has metal threads. I've read where its best to try and avoid plastic to metal threads. I'm just a diy'er. Also where would be the best place to install a ball...

    Pipes hammer/squealing while water is running

    Water pressure in my home was at 120 psi. I replaced the existing PRV with a new one and my water pressure is currently 45 psi. Now when I run water I get a loud hammering/squealing noise from the pipes while the water is running but it doesn't happen all the time. The most consistent way to see...

    High static pressure, Low flow and low running pressure

    Hi, I recently purchased an older home (1974) that is on county water. Since moving in, we have had fairly low pressure when using any faucet or toilet. When showering and a toilet is flushed, the pressure/flow drops to near nothing. I didn't think much of it but finally got a gauge and checked...

    High initial pressure that tapers off after 10-20 seconds

    I did a quick forum search and I'm not sure I have the same issues others have had with needing to install expansion tanks. When I turn on either hot or cold (or mixed) the initial pressure is somewhere around 150psi (confirmed with a gauge at the hose outside). Then after 10-20 seconds or so...

    New Hot Water Heater Or Prv Valve Issue

    I recently had a new gas hot water heater (apparently the dreaded flame-lock whirlpool) installed with a new thermal expansion tank. On hot-water demand once the gas flame starts the heater makes a popping sound followed by tuning fork ringing sound. After about 10 seconds all sounds from the...
