Why My Sump Pump Constantly Running?

Your sump pump works around the clock to make sure your basement and property is not overcome with flooding and excess moisture. This does not mean that the sump pump is constantly running though. If your sump pump is running without stop, then you have a problem that needs to be addressed as soon as possible. A constantly running sump pump can wear out its motor and shorten the service life.
At Mr. Rooter Plumbing of New Jersey, we have plenty of experience detecting, diagnosing, and resolving issues with sump pumps, and we are always ready to take your call for an emergency repair. But this article is not a sales pitch. It is an informative one. We hope to give you some insight into why your sump pump is constantly running and offer some tips to troubleshoot and fix the issue. You are always welcomed to call Mr. Rooter Plumbing to speak with a live representative.

Potential Cause #1: Faulty Float Switch

The name is pretty self-descriptive. A float switch sits on the surface of the water in the sump pump and switches the sump pump on when the water level reaches a certain point. Water is pumped out until the float pump reaches its neutral position once again.
Inspect your sump pump and make sure it is not tangled or stuck. Remove any obstructions so that it can freely move. If there is no obstruction, then the float switch may be faulty and need to be replaced. Many home improvement stores have replacements for sale but make sure you buy the correct type for your sump pump model.

Potential Cause #2: Defective Check Valve

The sump pump relies on the check valve to send water away without the same water coming back into the sump pit. A defective check valve will allow water to re-enter the sump pit, creating a loop that will be constantly triggering the pump.
Check to see if the check valve is properly installed. It should be held in place with ring clamps, so it is not very difficult to remove and replace the part. It may also be that the check valve has worn out. Either way, head out to the local hardware store to get a replacement part and swap out the old part for the new.

Potential Cause #3: Clogged Discharge Pipe

The wastewater discharged by a sump pump travels through a discharge pipe. It is common for sediment and debris to clog the discharge pipe. If the discharge pipe is blocked, then water backups will have your sump pump running non-stop.
You can grab a plunger or drain snake to unclog the pipe, but we do not recommend chemical drain cleaners. If the drain snake or plunger does not loosen up the blockage, then consider calling Mr. Rooter Plumbing of New Jersey for a professional cleaning. Our live representatives and qualified plumbers are available around the clock. Do not ever hesitate to call.
