Most pumps only require a maintenance check once or twice a year.

Learn the seven core sump pump maintenance steps and how to spot problems in advance.

What Is a Sump Pump?

A sump pump is an electric pump that moves water from the basement to the exterior.

When the water level reaches a pre-determined height, the pump automatically turns on and expels the water.

When the water level drops, the pump turns off.

The best way to test is to pour water into the sump pit.

You will need to pour a generous amount to cause the pump to turn on.

After the pump activates, stick around to verify that the water is discharged.

You may have to scrape the sludge and grime away to get it fully clean.

If the power must be on or connected while you’re working on it, take precautions.

Pay careful attention to the areas around the battery, the float switch, and the inlet screen.

If you see any components of your sump pump that look particularly worn, be sure to replace them.

Lubricate Bearings

Lubricate the bearings during your annual maintenance routine if you have unsealed bearings.

Your manufacturers recommendations should indicate whether or not this needs to be done.

you’re able to test to see to it your battery is working by unplugging the pump.

Or you mighthave a blown fuseor tripped circuit breaker on the service panel.

If not, replace the switch.

Look at the discharge pipe and clear any obstructions.

Also, a sump pump that constantly runs might be undersized for the job.

Stepping up to a higher-level pump with greater discharge is the only solution.

But often, the solution is simply that the discharge pipe might have an obstruction that causes backflow.

Thus, water that tries to discharge is prevented from doing so.

The water runs backward, filling the sump pit, and causing the sump pump to start up again.

Expect to pay about $150 to $250 yearly for professional sump pump maintenance.

If the sump pump runs frequently, increase the service schedule to twice yearly.

Experts typically recommend replacing a sump pump once every 10 years, even if it’s still working.

you’re able to dump water in your sump pump to test it.

However, do not introduce large volumes of water.

This can shorten the life expectancy of your sump pump.

You do not always need a sump pump in your basement.

Many basements have no groundwater issues, so there is little to no need for a sump pump.
