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.

Can a pressure regulator cause a water leak?

Ultimately, such pressure can damage water-using appliances and may even lead to leaks and the problem known as water hammer. Fortunately, you can keep your water pressure within a safe range by installing a pressure regulator valve on your main water line.

How does a pressure regulator work on a faucet?

A water pressure regulator valve works in much the same way as an outdoor hose faucet. A screw at the top allows you to increase or decrease the flow of water through the valve. Tightening the screw restricts water flow and hence places a tighter limit on the maximum water pressure.

What’s the difference between a water pressure reducer and a pressure regulator?

A water pressure reducer or pressure reducing valve is a device that lowers high incoming water pressure to a safe level in a building. A water pressure regulator is a device that attempts to keep building water pressure at a consistent level.

What is a water pressure regulator and why do I need one?

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. This valve brings down the pressure to a safe level before the water reaches any plumbing fixtures inside the home.

How do you test a water pressure regulator?

To determine if you need a water pressure regulator test the water pressure of the main water supply to your house. You can buy a pressure gauge for local hardware or home improvement store. Screw the pressure gauge onto any hose bib or washing machine bib and turn the water on to measure the water pressure.

What does the water pressure regulator do?

A water pressure regulator is a plumbing safety feature which is designed to prevent water pressure from climbing too high while also ensuring that the pressure remains high enough for consistent flow from faucets, taps, and shower heads. This device is often located near the water main on the outside…

Why does a home water pressure regulator go bad?

There are several reasons that a pressure regulator goes bad. One common cause is age. As the regulator is severely tested over the years by pressure fluxuations, it can end up suffering from stress and decay. This natural aging process makes it necessary to replace it as soon as possible.
