How to Maintain a Sump Pump (Before You Need It)

4 min read·Updated July 18, 2026

A sump pump sits idle for months, then has one job during the worst storm of the year. Ten minutes of maintenance is the difference between a dry basement and a flooded one.

How often to check it

  • Every 3–4 months: pour a bucket of water in the pit and confirm it kicks on and drains.
  • Twice a year (spring & fall): full clean-out and inspection.
  • Before storm season: test, plus check your backup.
  • Every 7–10 years: expect to replace the pump itself.

The 10-minute inspection

  1. 1Unplug the pump. Clear any debris from the pit and the intake screen.
  2. 2Check that the float moves freely and isn't stuck against the wall.
  3. 3Plug it back in and pour in water until the float rises — it should start promptly and shut off after draining.
  4. 4Go outside and confirm the discharge line is clear and directs water away from the foundation.
  5. 5Make sure the check valve holds (water shouldn't flow back into the pit).

Test it the same weekend you change your clocks — an easy twice-a-year anchor you won't forget.

The backup that matters

Storms cause floods and power outages at the same time — right when your pump goes dead. A battery backup pump (or a water-powered backup) keeps the pit draining when the grid is down. If you have one, test it too; a backup you never check is a backup you don't have.

Put it on autopilot

Add your sump pump to Upkeepery and it schedules the quarterly test and the pre-season check, and reminds you before storm season — so the one appliance you can't afford to have fail is the one you actually maintain.

Never forget this again

Upkeepery schedules this and everything else your home and car need, and reminds you before it's due. Free forever.
