What is a Pressure Reducing Valve (PRV) and Why Do I Have One?

How Does a Pressure Reducing Valve Work

Should you be looking near your main shut off valve in your home (which we sure happen frequently) and you notice a cone-shaped valve near it, you may ask yourself, “What could that be”?  The answer may (or may not) surprise you.  That cone shaped-valve is called a Pressure Reducing Valve (PRV) and it is sometimes a necessity to control the water volume in your home. They are small, relatively inexpensive valves that are typically located near your water meter.

Does a PRV reduce my sinus pressure? What about the pressure from my job?

Unfortunately, your PRV does neither. Although it does control the water pressure in your home, making it a comfortable pressure to use and keeping your water bill under control. It can help to conserve energy that is being consumed within your home, and it can save you money on maintenance of the other plumbing in your home.   It can also save you money on your monthly bills.

If you hear banging pipes in your home or water appears to be gushing from an open tap, you can determine that you probably have excessive water pressure in your home.  You may also need to replace your PRV if you have low water pressure throughout your whole home.  You can also get your water pressure tested by a plumber or your water company.

Does my PRV last a lifetime?

Your PRV will last approximately 10 years under regular use.  We recommended replacing your PRV after 10 years to prevent it from going out, which can cost you more than just a headache. When a PRV goes bad, it can cause your home to have immediate excess or decrease in water pressure, which can be very symptomatic. Symptoms include banging pipes, no/intermittent water, and/or the valve itself can begin to leak.
