Should You Repair or Replace Your Sump Pump?

In many homes, a sump pump is what stands between your basement and outside moisture. For this reason, the pump should work properly.

Constant Cycling

Cycling is a term used when a sump pump is constantly turning off then almost immediately turning back on. The result is an almost cycle of constant on-off operation. Not only is it annoying to hear, but it is also a waste of power and it is damaging to the pump itself. In the event the cycling is occurring during a rain or flood event, it can also mean your home is in danger of water damage since the pump is not running and pumping consistently.

The good news is that often this is a repairable issue. The usual culprit is a malfunctioning float switch or a short in the wiring. Float switches can be replaced and wiring can usually be repaired. If the pump is older and at the end of its expected operational life, or if there are additional mechanical issues, it may make more financial sense in the long run to have it replaced.

Strange Noises

Sump pumps don't typically operate completely in silence, but they shouldn't be so noisy that they interrupt day-to-day life. Generally, a properly functioning sump pump will only produce a gentle hum, as you would expect from any motor-operated device in your home.

Banging, squealing, rumbling, and vibration noises are all signs of trouble. Vibration-induced sounds may only indicate that something is lose, such as the mounting hardware, which is easily repairable. Squealing typically indicates a lubrication issue or a belt failure, both of which can be repaired with a little routine maintenance work. Banging and rumbling noises, on the other hand, can be signs that the motor is wearing out or that a large mechanical failure is imminent. Often, replacement is the best option.

Frequent Malfunctions

Like any appliance in the home, your sump pump should be subjected to routine maintenance about once a year. For the most part, this should all but eliminate unexpected breakdowns because the pump will be properly adjusted and lubricated, and worn parts will be replaced before they fail.

If you have an older pump, a pump with visible issues like rust, or are simply experiencing frequent malfunctions even though the pump has been regularly serviced, then it is reaching the end of its working life. At this point, the best option is to install a replacement sump pump.
