How to Reset A Sump Pump

Last Updated on by Anthony Brown

If your sump pump is not running quite as good as the day it was installed it might need to be reset. Your sump pump is responsible for pumping ground water that builds up in your basement into the sewer or drain. Most pumps from name brand companies – like Zoeller – are well made and rarely need restarting but every pump needs some maintenance from time to time!

Resetting your pump is easy and only takes a few minutes. Let’s go over the 6 steps so you can reset your pump and clear out and debris that might cause failure and flooding!

Step 1 - Disconnect the Power

Want to avoid a shocking experience – then make sure to disconnect the power before you start. We recommend starting by shutting off the power at the breaker then disconnecting the power cord. Anytime you are working on electrical gear around water it is important to take every precaution!

Step 2 - Remove the Pump

Next, remove the basin cover and take your pump out of the basin. Make sure to disconnect any drainage pipes without damaging or bending the pipes or pump connectors. We recommend setting the pump system on an old towel or tarp since it will be damp and dirty plus water might come out of the check valve!

Step 3 - Clean Dirt & Debris

Third, clean any dirt, debris or small pebbles that have collected in the bottom of the pit. If your pump has a filter make sure to give it a good cleaning! One of the most common causes of stalled motors is small rocks getting inside the pump body and jamming or blocking the motor. Sump pumps and basin pits collect dirt and grime over time, cleaning them will extend their lifespan and prevent future problems.

Step 4 - Check Drain Lines

Before reattaching your pump check that the drain lines and discharge pipe are free of clogs and in good working order. Clogged drains means your pump has to work harder than it needs to – increasing your risk of a smoking pump and causing extra noise (unless you have one of these super quiet pumps)!

Step 5 - Reconnect Everything

The final step in resetting your pump is to put everything back together how you found it! If you can’t remember – or things don’t seem to fit – check your owners manual and installation guide! Reconnecting everything is one of the most important parts of resetting your pump – one wrong step and you could have an expected leak on your hands! Before you are done make sure the float switch can rise and fall with the water level in the pit.
