Why Won’t My Sump Pump Stop Running?

A sump pump is your home’s first line of defense against basement flooding. You want this machine to work properly when it’s supposed to, so it’s important to learn how to recognize issues before they turn into costly problems. One issue that homeowners may run into is a sump pump that runs continuously. Any machine that runs constantly is at risk of overheating and breaking down. Luckily, this is a situation that North Vancouver plumbers can fix easily. Here are the key reasons why your sump pump won’t stop running.

Float Switch Failure

If your pump is running all the time but there’s no water coming out, a failing float switch is the most likely reason. The float switch that sits in the sump pit is designed to float on top of the water. If the water rises past a certain height, the switch triggers the pump. A sump pump that runs non-stop without water coming out likely has a float switch stuck in the on position.

Check Valve Malfunction

Since pumps must be installed below ground level to be effective, the discharge pipe that directs water out of your home runs vertically for the first few feet. The check valve is there to stop water from returning into the pit. When this valve is broken or not working properly, the water constantly flows backwards into the sump pit, causing the pump to run continuously to try and eject the water.

Plumbing and Drainage System Issues

If you have a sprinkler system or a pool, there may be an underground leak that’s causing water to seep into your basement and sump pit. Other plumbing issues like a ruptured sewer pipe could also be the culprit. In those cases, it’s important to investigate the issue without delay, because underground water leaks can wreak havoc on your home’s foundation and result in costly repairs.

Your Home Was Built in the Wrong Place

Some houses are built too close to the water table line or near a rock shelf that directs water back towards the structure. If this is the case with your home, a sump pump that runs non-stop is the only thing stopping the basement from flooding. Consider installing a second pump in case the first one fails.
