Sump water must not go into the sewer. Water in the basement because of grading or downspouts needs a look at the whole path the water takes. Member prices are for Quality Service Club members. Starting prices from our 2026 pricebook. A real person confirms your price before anything is scheduled.

Know the signs

Signs your pump needs work.

Pumps rarely announce a failure. They just don’t start on the night you need them.

Runs constantly

A stuck float, a check valve letting water fall back, or a pump too small for what comes in.

Doesn’t start

Pour a bucket of water in the pit. If the float rises and nothing happens, it has failed.

Alarm sounding

Water or sewage is rising in the basin faster than the pump moves it.

A frozen discharge line

In a hard freeze the outside line can ice shut, and the pump burns out pushing against it.

How it works

Test. Replace. Protect.

Test the pump twice a year: before the spring thaw and before the freeze.

  1. 01

    Test

    We fill the pit and watch the pump start, empty it and shut off.

  2. 02

    Replace

    A failing pump is replaced and tested in place.

  3. 03

    Protect

    A check valve and a high-water alarm so the next failure doesn’t surprise you.

Questions

Sump & ejector pumps, answered.

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

How much does a new sump pump cost?
Replacing a sump pump starts from $862 at Gold Seal. A new check valve starts from $364 and a high-water alarm from $451. Installing a pump you bought starts from $488.
What is a sewage ejector pump?
A pump in a sealed basin that lifts waste from a basement bathroom or laundry up to the main sewer line, which sits higher than those fixtures. Unjamming one starts from $638, and replacing a submersible ejector pump from $1,679.
Why does my sump pump run constantly?
Usually a stuck float switch, a failed check valve letting water drain back into the pit, a pump too small for the inflow, or a high water table after heavy rain or snowmelt. The first three are repairs, and constant running burns a pump out quickly.
Can the discharge line freeze?
Yes, and it is a common failure in the Inland Northwest. When the outside line freezes solid, the pump runs against a blocked pipe and burns out, often unnoticed until the thaw. Check the outlet after a hard freeze.
How often should I test my sump pump?
Twice a year, in early spring and late fall. Pour a five-gallon bucket of water slowly into the pit: the pump should start, empty it and shut off cleanly. Most sump pumps last seven to ten years.
