What to Do If Your Sump Pump Stops Working

Written By Breanna Palumbo

If your sump pump fails during heavy rain, your basement can flood within hours — a common issue in Northern Virginia homes, especially in Leesburg, Ashburn, and Sterling.

Here’s what to check before calling a plumber.

1. Check the Power Source

Sump pumps frequently fail because they lose power.
Make sure:

  • The pump is plugged in

  • The breaker hasn’t tripped

  • The outlet has power

2. Look for a Stuck Float Switch

The float switch tells the pump when to turn on and off.

If it gets stuck:

  • Gently lift the float

  • Clear debris

  • Ensure it moves freely

3. Inspect the Discharge Line

Frozen or clogged discharge pipes prevent the pump from releasing water.

Signs:

  • Pump runs but doesn’t move water

  • Gurgling noises

4. Clean the Sump Pit

Debris, mud, and gravel can block the pump inlet.

5. Test the Pump

Pour a bucket of water into the pit.
If the pump doesn’t activate, it may need repair or replacement.
