How do I know if I need a water pressure regulator?

If the water pressure level coming into your home from the city exceeds 80 psi, you need a water pressure regulator. Reducing the system pressure 10 to 20 psi can save thousands of gallons a year in the typical home.

What do you need to know about a water pressure regulator?

A water pressure regulator is a device that attempts to keep building water pressure at a consistent level. As you can see in the sketch above, the key parts inside a typical water pressure reducing valve are: an adjustment screw & lock-nut that permit changing the spring pressure.

Why are control valves called low pressure regulators?

We notice that in low pressure regulation applications such as on steam heating systems and on residential water supply systems, control valves are referred to as low pressure regulators (Watts 123LP low water pressure regulator for example – sketch at left).

Why do two stage regulators have two safety valves?

Two stage regulators may have two safety valves, so that if there is any excess pressure between stages due to a leak at the first stage valve seat the rising pressure will not overload the structure and cause an explosion. An unbalanced single stage regulator may need frequent adjustment.

What do you need to know about an irrigation regulator?

The closing of the area between the seat and the t-stem reduces the water pressure on the diaphragm. The balance between the force on the diaphragm and spring resistance establishes the outlet pressure. Irrigation pressure regulators need outflow and back pressure to regulate the pressure within your irrigation system.

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.
