Signs your pressure regulator is failing

  • Pipes that bang or hammer when a faucet or appliance shuts off
  • Toilets that run or refill on their own, or faucets that drip
  • A water heater relief valve that drips or discharges
  • Pressure that suddenly drops very low, or surges
  • Washing machine or icemaker hoses that burst

Why water pressure matters

Water often reaches homes in our area at high pressure. A pressure regulator (also called a PRV or pressure reducing valve) sits where the water line enters your home and brings that pressure down to a safe level. California's plumbing code calls for a regulator when street pressure is above 80 psi, and most homes do best between about 50 and 70 psi.

Regulators wear out, often after 10 to 15 years. When one fails, the full street pressure goes straight into your plumbing, and every faucet, toilet valve, supply line and water heater pays the price.

Testing and replacement

We test your water pressure with a gauge, so you'll see the number for yourself. If your regulator has failed, we replace it, set it to the right pressure and test again. When the main shutoff valve next to it is old or stuck, we can replace both together so you have a reliable shutoff in an emergency.

Frequently asked questions

What should my home's water pressure be?

Most homes do best between about 50 and 70 psi. California's plumbing code calls for a pressure regulator when incoming pressure is over 80 psi.

How long does a pressure regulator last?

Often 10 to 15 years, though hard water can shorten that. If your home is older than that and has never had it replaced, it's worth having the pressure tested.

Can high water pressure damage my water heater?

Yes. High pressure strains the tank and can make the relief valve drip. A working regulator, along with an expansion tank where needed, protects it.
