A sump pump keeps moisture and water out of your basement and crawlspaces during heavy storms and inclement weather. If it's not working correctly, however, your basement can be susceptible to water damage, mold, rot, and structural instability. While a professional can minimize any harm caused by a malfunctioning pump, it may be confusing to determine when there's a problem. Here are the answers to a few common questions about malfunctioning sump pumps.

A Guide to Troubleshooting Sump Pumps

Why do sump pumps fail?

Like any mechanical device, sump pumps can simply be overwhelmed by the sheer volume of water. Constantly trying to bail out your basement can burn out the pump, especially if it’s several years old. In these cases, you may need to replace the pump with a higher-capacity model or install a second device on the other side of the basement.

How are sump pumps activated?

Most pumps are switched on automatically by pressure sensors or a floatation device, much like those found in toilet tanks. If there’s a mechanical issue with the flotation arm or the sensor is damaged, the pump may not activate when water levels rise.

A tripped circuit breaker or burned-out motor can also cause your pump to fail. Check your home’s electrical panel for breakers that are in the “off” position. If the problem persists, have a professional examine the pump and the wiring for potential shorts.

Should sump pumps have lids?

Sump pumps rest in pits dug into the basement floor, which should always be protected by a lid. Without a covering, dirt and debris can find their way into the pit and eventually clog the pump. If your device stops working and doesn’t have a lid, there may be an obstruction in the drainage line. 

When the obstruction is removed, find an airtight covering that fits along the basin. Since these lids come in different sizes, measure the area to find the right fit for your equipment.

How do I maintain a sump pump?

Sump pumps are fairly maintenance-free, but they should be turned on briefly every two to three months to ensure everything is running smoothly. Some manufacturers also recommend taking the pump out, lubricating the bearings, and checking the seals before spring every year. You can also add a bucket of water to inspect the float arm and ensure the sump pump turns on.
