Can a water pressure regulator get clogged?

A water pressure regulator valve works in much the same way as an outdoor hose faucet. Unfortunately, over time, a regulator valve may develop blockages that restrict flow beyond the intended amount. Such blockages often stem from high mineral content in your municipal water supply.

What causes a pressure regulator to fail?

Contaminants, like dirt, lint, rust, sludge, or even the misalignment of the valve can cause the pressure relief valve to stick. At this point, you might see that your system is above pressure, or you’ll notice other pressure relief valves in the system releasing to make up for this valve’s malfunction.

What do you need to know about a pressure regulator?

Richard Epstein is a licensed master plumber with over 40 years experience in residential and commercial plumbing. A water pressure regulator (sometimes called a pressure-reducing valve, or PRV) is a specialized plumbing valve that reduces the water pressure coming into the home through the main water line.

How often should you test your water regulator?

Test the water pressure with a gauge if there is any question of the regulator’s effectiveness. Testing the water pressure at least once a year is always a good idea.

Where is the regulator on a water meter?

Locate the water pressure regulator on the incoming main water line. This bell-shaped device (usually made of brass) is positioned near the water meter. Note the long screw going through the top center of the bell. Next to the brass housing is a lock nut securing the adjustment screw in place.
