Sump Pump Repair for Homes Across the GTA

A sump pump usually fails in one of four ways: the float sticks, the switch dies, the check valve leaks back, or the motor gives out. Each has a tell.

  • Pit, pump, float and check valve tested together
  • Backwater valve options for the main drain
  • Water poured through to prove it works

Signs it is time to call

A pump that hums but moves no water, one that runs constantly, one that cycles every few seconds, or a pit filling to the rim while the pump sits silent all need attention. So does a loud clunk every time the pump shuts off, which usually means a failing check valve letting the column of water drop back.

Pour a bucket in the pit before the storm, not during it.

On the job, step by step

We test the outlet and breaker first. Then we lift the float by hand to see whether the pump starts. If it does, the float was hung up on the pit wall or a cord. If it hums, the impeller may be jammed with gravel. If nothing happens, the switch or motor has failed. We also check the check valve, the discharge for ice or crushing, and the pit for silt that chokes the intake.

Hums, no waterJammed impeller, frozen discharge

GTA houses and what they change

Pumps in GTA basements work hardest in spring thaw and summer storms. Pits that collect fine silt from clay soil wear impellers faster. Old pumps installed with flexible hose and no union are hard to service; we often replace that plumbing at the same time. A pump past about ten years of hard work is usually better replaced than repaired.

Before you pick up the phone

Ask whether the plumber carries replacement pumps on the truck so you are not left without one overnight. Call (365) 387-8531.

Common questions

What lifespan should a sump pump have?

Run time decides it. Many last seven to ten years; a pump in a very wet pit may wear sooner.
