WHAT IS A PRV? DO YOU HAVE ONE IN YOUR HOME?
Maybe / Maybe Not - Do you need one?
Pressure Reducing Valves - (PRV)
Frequently Asked Questions
Pressure Reducing Valves (PRVs) are a type of valve installed in the plumbing of homes to regulate water pressure. The purpose of a PRV is to reduce incoming water pressure from the water company mains to a pressure that is safe for a home’s plumbing system. PRVs are also a water conservation tool. By avoiding higher than required pressure, water is conserved. The PRV is installed at the water service entry point of homes after the first shutoff valve and before the water meter assembly.
1. Does every house have a PRV?
No. For example, in Highlands Ranch the water standard specifications: a PRV is not required if water main pressure is less than 65 psi.
2. What should the pressure be set at in my home?
Standard specifications state the pressure should be atleast 40 psi and no greater than 80 psi.
3. What pressure range does a PRV have?
Most residential PRVs have an operating range between 25-75 psi, and are preset at
the factory at about 45 psi.
4. Can I move my PRV above the meter and the irrigation tie in to have better pressure for my irrigation system?
No. The PRV is placed before the water meter to protect it. Placing it after the meter
could subject the meter to high pressure causing it to fail, and possibly causing
damage to your home.
5. What are the symptoms of a PRV that is no longer working properly?
A sudden loss of, or a gradual reduction in water pressure within the home for no apparent reason. A banging or high pitched whistling sound coming from the pipes usually when the water is being turned off. PRVs may also fail in the open position providing higher than desired pressures. Typically there is no indication this may have occurred other than noticeably higher pressure at the faucet or toilets that continue to run after the bowl is filled.
6. How do I know if my PRV is working properly?
Perform a pressure check yourself, have a qualified plumber or request the water department to do the test.
7. Will the water company repair or replace my PRV?
No. The PRV is part of the home’s plumbing and is owned by the homeowner. A new PRV can be purchase at most hardware or home supply stores. Another option is to contact a plumber to have a new PRV installed.
So now you know what a PRV is. Do you have one in your home? Maybe, maybe not.
Do you need a PRV? First, you will need to test your water pressure and check with the water company. They may do a free pressure test, try contacting them.
If you have a PRV, your water pressure may be adjusted up or down, but you will need to retest your water pressure after you make the adjustment to ensure the water pressure is within limits of the water company.
