Protect Your Plumbing from High Water Pressure

City water can reach your home at a higher pressure than your plumbing is built to handle. A pressure reducing valve, or PRV, sits where the water line enters the house and brings that pressure down to a safe level. When a PRV wears out, pressure can climb high enough to cause leaks, banging pipes and early failure of your water heater and fixtures, or it can drop and leave you with weak flow.

Mountain Vista Plumbing tests, repairs and replaces pressure reducing valves across Mesa, Gilbert, Chandler, Queen Creek, San Tan Valley, Apache Junction and Gold Canyon.

Signs Your Pressure Reducing Valve Is Failing

  • Banging or hammering pipes when faucets or appliances shut off.
  • Faucets and showers that blast when you turn them on.
  • Toilets that run or fill valves that keep failing.
  • A dripping water heater relief valve.
  • Repeated leaks at supply lines, hose bibs or fittings.
  • Pressure that jumps around or suddenly drops.

What We Do

  • Test your water pressure with a gauge
  • Adjust, repair or replace the pressure reducing valve
  • Check that thermal expansion is handled at the water heater, since a working PRV can create a closed system
  • Repair leaks and damage caused by high pressure

Most homes do best between about 40 and 80 psi, and plumbing code calls for a pressure reducing valve when incoming pressure is over 80 psi.

PRV FAQs

How long does a pressure reducing valve last?

Many last 10 to 15 years, but Arizona hard water can shorten that.

Can high water pressure damage my water heater?

Yes. Constant high pressure strains the tank, fittings and relief valve. See our water heater page.

Is a PRV the same as a backflow preventer?

No. A PRV controls pressure, while a backflow preventer keeps water from flowing back into the drinking water supply.
