In Edmonton, your sump pump earns its keep during spring melt and heavy summer storms — the exact moments a failure turns a finished basement into an expensive cleanup. The good news: pumps almost always warn you before they quit. Here are five signs to watch for, ideally before the water table rises.
1. It runs constantly or won’t shut off
A pump that runs non-stop — even when it hasn’t rained — is a red flag. It could be a stuck float switch, an undersized pump, or a high water table overwhelming the system. Constant running wears the motor out fast, so it’s worth checking before it burns out.
2. Strange noises
Grinding, rattling, or loud humming usually means a worn impeller, a jammed component, or a motor on its way out. A healthy pump runs with a low, steady hum — anything harsher is a warning.
3. It cycles on and off rapidly
Short-cycling — switching on and off every few seconds — often points to a faulty float switch or a pump that’s wrong for your pit size. It’s hard on the motor and a common precursor to failure.
4. Visible rust or age
Rusty water or corrosion on the unit signals wear (or bacteria that can clog the works). And age matters: most sump pumps last around 7–10 years. If yours is past that, treat it as living on borrowed time — especially heading into spring.
5. The pit fills but the pump doesn’t kick in
If water is rising in the pit and the pump stays silent, stop and get it checked. This is the failure mode that floods basements. It’s often a stuck switch, a wiring issue, or a seized motor — and it needs attention now, not next month.
When to repair vs replace
- Under ~7 years and a minor fault (switch, check valve) → usually a repair.
- Older than 7–10 years, or repeated problems → plan a replacement.
- No backup and a finished basement → add a battery backup regardless.
- Building or finishing a basement → size the system for the water your home actually sees.
