Sump pump failed in Leduc or Beaumont? 5 things to do before the basement floods
Power, prime, and discharge — the three reasons a sump pump suddenly stops moving water. Here's what to check, in what order, before water reaches the floor joists.
What to do, in order
Check the breaker and the outlet first
Most "dead" sump pumps aren't dead — they tripped a GFCI or shared-circuit breaker. Find the outlet the pump is plugged into (usually right above the pit) and reset the GFCI button. If it pops again immediately, stop and unplug; you have a moisture or motor short and pushing the reset will burn the pump out.
If the breaker holds, give the pump 30 seconds. A working pump should kick on as soon as the float rises.
Look at the float and lift it manually
Pumps don't run unless the float tells them to. Reach in (with the pump unplugged) and lift the float arm to see whether it moves freely. Common failures: the float gets pinned against the pit wall, the tether wraps around the discharge pipe, or sediment locks the float at the bottom.
Free the float, plug back in, and listen for the pump to cycle.
Check the discharge line outside
If the pump runs but no water is leaving the pit, the discharge line is the next suspect. Walk outside to where the pipe daylights — almost always the side or back of the house. In a dry pit it's an obvious blockage; in spring melt it's often the discharge frozen solid or buried under ice from the previous freeze-thaw cycle.
If you can clear the outlet (a careful kettle of warm — not boiling — water poured around the buried section will usually free it), the pump should immediately start emptying the pit.
Bail or shop-vac to buy time
If the pit is already filling faster than you can troubleshoot, get water out of it any way you can. A 5-gallon shop-vac is the fastest tool most homes have. Empty into a tub or laundry sink, not back near the foundation.
This isn't a fix — it's how you keep the basement dry while you wait for help.
Start a job if water is still rising or the pump is dead
A failed pump on the high water table belt isn't a tomorrow-morning problem. The OnCall Pros network routes Leduc and Beaumont sump-pump emergencies on RED-lane priority to plumbers carrying replacement pumps and fittings on the truck — typical on-site under 30 minutes.
What not to do
- Don't pour boiling water into a frozen discharge line — it can crack the pipe.
- Don't reset a GFCI more than once if it keeps tripping (you have a short).
- Don't run an extension cord across a wet floor to power the pump.
- Don't assume a working backup pump means you can ignore the primary — they share the same float and pit.
When it becomes urgent
- Water is within 6 inches of finished flooring.
- The pit is filling faster than your shop-vac can empty it.
- The pump is running but you can hear the motor labouring.
- There's a burning smell from the outlet or pump body.
Edmonton context
Leduc, Beaumont, and the southern fringe of the Edmonton metro sit on a higher water table than the river-valley core, which is why sump-pump failures here are dramatically more time-sensitive than in north Edmonton. Spring melt (late March through April) and any sustained rain event push pit-fill rates we don't see anywhere else in the network. If your sump alarm has gone off twice in the same season, it's worth asking the responding plumber to quote a battery-backup secondary pump while they're on-site — the install cost is small relative to a single basement-flood claim.
Frequently asked questions
- How fast can a basement flood after a sump pump fails?
- On the high water-table belt around Leduc and Beaumont, an active spring-melt sump pit can refill in under 5 minutes once the pump quits — basements have taken on 2-3 inches of water within an hour in the worst recorded calls.
- Should I have a backup pump?
- On this side of the metro, yes. A battery-backup secondary pump (or a water-powered backup if your home has municipal pressure) costs a fraction of a single flood-restoration claim and runs automatically when the primary fails or the power's out.
- Can I install a replacement pump myself?
- Mechanically, yes — it's a swap. But Alberta plumbing code requires the discharge connection and any check-valve work to be done by a ticketed plumber if it's tied into the home's drainage system. For an emergency replacement, the time cost of a permitted install is what you're paying for; the part itself is the cheap part.
- Why does my pump cycle on and off constantly?
- Either a stuck check-valve letting water flow back into the pit (most common), an undersized pump for the water volume, or a cracked discharge line letting water re-enter. A 15-minute on-site check usually identifies which.
