How to Test Your Home Sump Pump Before a Storm

Most homeowners spend very little time thinking about their sump pump. In fact, some have no idea what it is or why it’s so important until it stops working during the middle of a storm.

The good news is a simple sump pump test only takes minutes and could save you thousands of dollars in water damage repairs. Here’s how to test if your sump pump is working.

What Is a Sump Pump?

Sump pumps are installed in a basin at the lowest part of the basement or crawlspace to prevent groundwater from entering your home. When groundwater flows into the sump pump pit, the pump automatically activates, removing excess water through pipes that drain outside the home.

This simple but effective system keeps basements and crawl spaces dry and helps avoid costly cleanups due to floods and heavy rainfall.

Testing Your Sump Pump

To ensure your sump pump is functioning properly, we recommend testing it at least once a year for newer units and once every three to four months for older ones.

Visual Inspection

Begin by inspecting the sump pump pit for any debris that could block the pump. While you’re at it, look for signs of rust or corrosion on the sump pump and note how it is positioned. Sump pumps should sit on a level surface and be far enough away from the walls of the pit that the float can move freely up and down.

Power Source Inspection

Next, check that the sump pump is connected to a ground-fault circuit interrupter (GFCI) outlet. Keep in mind that outlets should be located at a safe height above water levels and protected from moisture. Finally, look for any signs of fraying or wear on the power chord—anything that could impact the pump’s functionality.

Test the Pump Mechanism

The simplest way to test your pump is to simulate a hard rain. Simply fill a five-gallon bucket with water and pour it into the basin. Watch as the float rises with the water, turning on the system and pumping out the excess water.

During the test, listen closely for abnormal sounds indicating that your pump may not be functioning.

Inspect the Check Valve

The check valve (or one-way valve) on the discharge pipe prevents water from reentering the pit once the sump pump has stopped. Inspect it for cracks, leaks, or corrosion.

Troubleshooting Common Sump Pump Issues

Pump Isn’t Activating

If your sump pump does not activate when you pour water into the basin, confirm that you haven’t accidentally triggered a circuit. Next, check the float to make sure it is not caught or tangled.

Producing Strange Noises

Excessive humming is frequently a sign of a failing motor—a clear indicator that it’s time for a sump pump replacement. Gurgling and rattling are common indicators of an issue with your check valve or your pump needing to be leveled.

Stagnant Water

If the pump triggers with rising water but the device does not pump water out of the basin:

• Check for a clogged discharge pipe
• Ensure the check valve is working
• Look for frozen or blocked discharge lines

When It’s Time to Consider Sump Pump Replacement

While lifespan varies, the average sump pump will last between seven and ten years. However, if your sump pump is frequently cycling off and on, running nonstop, not running at all, or requires frequent maintenance, it may be time for a sump pump replacement.
