6 Reasons Your Sump Pump Is Running Constantly & Ways to Fix

A sump pump that cycles too frequently will wear out the motor prematurely and decrease the system’s lifespan. If you notice that your sump pump is running constantly, it might have one of the following problems:

Why Does My Sump Pump Keep Running?

1. Defective Float Switch

The float switch floats on the water’s surface and signals the sump pump to turn on. It moves up and down with the water level. When the water hits a certain level, the float switch starts the pumping process. The submerged pump pulls water in and moves it through the discharge pipe.

If a float switch is defective, the float and arm could be stuck and fail to pause after releasing water. The float switch might function normally but still be faulty. When looking for a replacement float switch, make sure you purchase the right one for your sump pump model. Contact an HVAC technician at 904-467-9674 with any questions.

2. Malfunctioning Check Valve

The check valve rests on the discharge pump that’s above the sump pump. The valve keeps water from flowing down the discharge pipe and back into the sump pump. If your sump pump keeps running during the day, a defective check valve may be the source of the issue. A malfunctioning check valve could cause the water to constantly move up and down the discharge pipe without being dispelled from the system.

To identify a broken check valve, start by making sure your system has a valve. If it doesn’t, you’ll need to purchase and install one. If your system has a check valve but still runs constantly, the check valve might be worn out from years of use and need a replacement. A check valve is easy to install or replace yourself.

3. Blocked Discharge Pipe

If the float switch and check valve are functioning properly, your sump pump might keep running because the discharge pipe is clogged. Sometimes dirt and other debris make their way into the discharge pipe and build up over time—resulting in a clog that blocks water from exiting the sump pump.

To fix this problem, try removing the clog with a wire hanger or drain snake. WARNING: do not pour a liquid drain cleaner into the sump pump to remove clogs.

4. Undersized Sump Pump

An undersized sump pump can’t expel water at the same rate that it enters the system. As a result, the sump pump runs longer than it’s supposed to as it tries to keep up with demand. If you realize that your sump pump is too small for the amount of water entering the system, you’ll need to get a replacement installed.

5. Clogged Inlet Screen

Some sump pumps require water to pass through an inlet screen before entering the system. This design prevents debris from entering the motor. While this feature is helpful to protect the motor from clogging, sometimes the inlet screen gets clogged. If the inlet screen gets clogged, water can’t flow into and out of the system like it should. This issue can cause the sump pump to run constantly as it tries to remove water.

Fixing a clogged inlet screen is simple:

  • Turn off the sump pump.
  • Remove the sump pump from the pit.
  • Carefully remove any debris from the inlet screen.
  • Return the sump pump to the pit, and turn it on.

If you experience any further issues after cleaning the inlet screen, have a Fenwick technician come take a look.

6. Broken Impeller

The impeller is a motorized fan that brings water into the sump pump and moves it up the discharge pipe. If this piece breaks, your sump pump will run constantly without bringing in or pushing out enough water.

Call us to have an HVAC technician determine whether your sump pump’s impeller is broken or just needs minor repairs.

Ways To Increase the Life Cycle of Your Sump Pump

If you want to save money, check out our five helpful tips to extend the lifespan of your sump pump:

1. Clean & Sanitize

A clean sump pump runs more efficiently, and an efficient sump pump puts less wear and tear on the system. If you don’t want to have to purchase a new sump pump anytime soon, make sure to clean and sanitize it regularly.

2. Inspect & Test

To test whether your sump pump is functioning properly, pour water into the basin and see if the float switch rises and lowers with the water level. If your system functions properly, it will last longer.

3. Clean the Drainage Pipes

Remove any debris or other clogged items from the drainage pipes so water can flow like it’s supposed to. Also, check for any leaky pipes. Following these two steps will protect your sump pump from getting damaged and wearing down too quickly.

4. Level It

If your sump pump isn’t level, the float arm won’t activity. Make sure your system sits on level ground or a level surface.

5. Inspect the Power Source

The easiest way to check for proper functioning and increase its life cycle is to make sure your sump pump is plugged into a power source.
