Q. Do I really need a pressure reducing valve (PRV) in my home? A. Yes.

In areas with high water pressure such as Draper – because our water comes down from the mountains – a PRV helps protect pipes, fixtures, and water-using appliances from damage or breaks.

PRVs can save you money by reducing the amount of wasted water in your home. A well-adjusted PRV will still give you plenty of water for your home’s needs.

Here are some pointers about effectively installing and using a PRV:

  • Most PRVs are adjustable. A qualified plumber can determine the right pressure for your home.
  • PRVs are not maintenance free. Have yours checked periodically to see if it needs repair.
  • Make sure your PRV doesn’t freeze! If it’s installed in an unheated area of your home, install insulation or heating tape to protect it.
  • If you’re installing or replacing a PRV, look for one that is approved by the American Water Works Association (AWWA) or Underwriters Laboraties (UL).
  • Your PRV protects your home from the high pressures that mainlines in the streets maintain.  PRV’s wear out, and can cause flooding in the home.  Operation, repair and replacement are all the responsibility of the homeowner.  The company cannot cover any damage that may occur from a poorly functioning PRV.
  • Make sure your water heater is next to a drain.  If your PRV goes out, usually the next thing to occur is the temperature and pressure valve (T&P Valve) will open.  This valve is designed to do just that, to prevent damage to the water heater.  There should be a pipe that extends down from the T&P valve towards the floor.  This pipe has to have access to a drain or flooding will occur. Sometimes the floor isn’t sloped properly to direct the water to the drain.  Homeowners should analyze this situation and make correction just in case this scenario happens.
