Why It Matters

A failed sump pump can lead to catastrophic basement flooding during heavy rain. Regular testing ensures it will activate when you need it most.

Before You Start

  • Ensure your hands and feet are dry and you are not standing in water when handling electrical cords.
  • Ensure you have the right tools and a safe workspace.

Step-by-Step Guide

1

Inspect the Pit

Remove the cover and check the pit for debris. Ensure the pump is upright and the float switch moves freely.

2

Test the Pump

Slowly pour a bucket of water into the pit until the float switch triggers the pump to turn on.

3

Check the Discharge Line

Go outside and verify that the water is discharging properly and flowing away from the foundation.

Common Mistake to Avoid

Not checking the backup battery system (if you have one). The primary pump is useless during a power outage without it.

Frequently Asked Questions

What do I do if the power goes out?

If you have a battery backup system, it will automatically take over. If you don't have a backup, you run a high risk of flooding during severe storms. It's highly recommended to install a battery backup or a water-powered backup pump.

What is a check valve?

It's a one-way valve on the discharge pipe just above the pump. It prevents water left in the pipe from flowing back into the pit after the pump turns off.
