Know the signs

Signs of a pressure problem.

Too much pressure wears out your plumbing. Too little makes the house hard to live with.

Pinhole leaks

High pressure pushes water through copper fast, which helps pinholes form.

A dripping relief valve

A water heater relief valve that drips can mean the pressure is too high.

Weak flow everywhere

A failing regulator, corroded supply pipe or a leak.

Pressure that comes and goes

Strong one minute and weak the next, as a worn regulator sticks.

How it works

Measure. Diagnose. Fix.

A gauge reading tells us which way to go.

01
Measure
We read the pressure at the main.
02
Diagnose
Too high, too low or unsteady, we find out why.
03
Fix
A regulator, a booster pump or a pipe repair, at an upfront price.

Questions

Pressure regulators & booster pumps, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

What should my water pressure be?

Plumbing code sets 80 psi as the most a house should see, and calls for a pressure reducing valve when street pressure is higher. Pressure that high wears out valves, appliances and pipe. A gauge on the main tells you yours; adding one starts from $541.

How much does it cost to replace a pressure reducing valve?

Replacing a standard 3/4-inch pressure reducing valve starts from $585 at Gold Seal, and a premium one from $831. Adding a regulator where there is none starts from $954.

Why is my water pressure low everywhere?

Usually a failing pressure regulator, corroded or partly closed supply pipe, a main valve that isn’t fully open, or a leak. When only one faucet is weak, the cause is at that faucet instead, most often a clogged aerator.

What does a booster pump do?

It raises the pressure of the water coming into the house when the supply can’t give you enough. A DAB booster pump starts from $2,666 floor mounted, or $2,874 wall mounted.

Do I need an expansion tank?

Often, once a regulator is in. A pressure reducing valve keeps water from flowing back to the street, so when the water heater heats and the water expands, the pressure has nowhere to go. An expansion tank absorbs it. One at the water heater starts from $629.
