Quick Checks Before You Call

NO POWER

Confirm power & the GFCI

Make sure the pump is plugged in, the GFCI isn’t tripped, and the breaker is on. Test the outlet with a phone charger or lamp. Free the float so it can rise.

RUNS BUT NO DISCHARGE

Check the discharge line & check valve

Inspect the outside pipe for ice, snow, or clogs. Verify the check-valve arrow points away from the pit; a failed or reversed valve sends water right back.

PIT OVERFILLING

Clear debris & free the float

Remove debris around the float and intake screen. Keep cords and the pump handle from blocking float travel so the switch can activate.

ALARM SOUNDING

Switch to backup if fitted

Silence the alarm, confirm water level, and switch to your battery backup if installed. If the primary runs hot or cycles without lowering water, stop and call.

AFTER A STORM

Extend the discharge away from the house

Add a hose/extension so water drains well away from the foundation. Ensure the outlet isn’t buried under mulch or snow.

FROZEN LINE

Thaw only the exterior section

Gently warm the outdoor section, never with flame, and add an ice-guard/freeze relief. If the line is frozen underground, call us for a safe bypass and repair.

Repair vs. Replace: what’s smarter in Hamilton basements?

When a repair makes sense

Most sump problems can be solved the same day by fixing the cause: a stuck float, failed check valve, frozen discharge, or a tripped circuit.

  • Stuck float or debris
  • No power or tripped GFCI
  • Short-cycling or water returning
  • Frozen or clogged discharge
  • Pump runs but moves little water
  • Odour or splash

When replacement is smarter

If the pump is near end-of-life, undersized for your pit, or the housing/impeller is worn, a new, properly sized submersible with a quiet check valve will protect the basement better.

  • Older than 7 to 10 years
  • Undersized for the pit or neighbourhood water table
  • Corrosion or cracked housing
  • Wrong style for the application
  • Upgrade for new features

FAQ — SUMP PUMP REPAIR IN HAMILTON

Typical life is seven to ten years for a quality submersible pump. Heavy water tables and frequent cycling shorten the life. We test cycle count and motor draw to advise.

Most homes use one third to three quarter horsepower. We size to pit volume, vertical lift, and discharge length, then verify with a flow test.

Quarterly: test the float, clear debris, and check the check valve for slam. Annually: clean the impeller, flush the discharge, and test the backup. Call if you smell burning, hear grinding, or see the pump running without lowering the water.

Submersible pumps are quieter and seal under a lid. Pedestal pumps are easier to service but are louder and more exposed. We choose based on pit size and noise goals.

A failed or missing check valve lets water fall back into the pit. A tiny pit or high float setting can also cause short cycling. We reset the float and install a quiet check valve.

Yes if outages or storms are common. A battery backup runs when power fails or the primary pump cannot keep up. We size the amp-hours to your pit and add a charger with alarm.

No. The City requires sump discharge to a storm line or to grade away from the house. We re-route lines and add freeze relief where needed.

Often yes. A spring-loaded or soft-seat check valve, a sealed lid with grommets, and vibration isolation on the discharge reduce noise.
