In a nutshell
Twice a year, before the spring thaw and before autumn storms, pour a pail into the pit and observe a full cycle. It takes five minutes and needs only a bucket.
Working through it
1. Check it has power
Plug firmly seated, outlet live, breaker on.
2. Lift the lid and look
Clear out gravel, silt and anything that has fallen in.
3. Give it water
Tip in a pail or two, gently, until the float rises.
4. Watch it cycle
The pump should start, drop the level quickly and shut off cleanly.
5. Go outside
Confirm the outlet pipe is spitting water and it is running off, away from the walls.
6. Try the standby
Pull the main pump's plug and run the drill again. The battery or water-powered unit should take over.
Clues worth noticing
- Humming with no water moving.
- A float that catches on the pit wall.
- A thud in the pipe when it stops.
- Running constantly in dry weather.
Signals that it needs a licensed plumber
If anything above shows up, book a repair before the next storm. See sump pump repair.
Calls we field, answered plainly
How long should a pump last?
Many go seven to ten years. Hard-working pumps less.
Is the alarm worth it?
Yes. A cheap high-water alarm warns you before the floor gets wet.
