If your pool cover pump is sluggish or not pumping, it’s more than just annoying. A slow or clogged pump can lead to standing water on your pool cover, which invites debris, algae, and even damage. Luckily, most issues can be fixed quickly with a few simple steps.
Here’s how to troubleshoot and fix a slow or clogged pool cover pump fast.
1. Unplug the Pump First (Safety First!)
Before you do anything, make sure the pump is unplugged. Even if it looks inactive, it could start unexpectedly. Safety first!
2. Inspect for Visible Debris
Leaves, twigs, and other debris can easily clog the intake of a cover pump. Start with a quick visual check:
-
Remove any large debris from around the pump.
-
Check the intake screen or grate for buildup.
-
Gently rinse off mud or gunk with a hose.
Pro Tip: A pump sitting in a leafy puddle is a clog waiting to happen. Try setting it on a brick or piece of plastic mesh to lift it slightly above debris level.
3. Check the Discharge Hose
A kinked or blocked discharge hose can back up water, making it seem like the pump isn’t working.
-
Detach the hose and flush it out with clean water.
-
Make sure it's not kinked or crushed.
-
Check that it’s long enough to direct water away from the pool area.
4. Clear the Impeller
If your pump sounds like it's running but water isn't moving, the impeller might be jammed.
-
Remove the housing (consult your user manual).
-
Look for small stones, twigs, or sludge.
-
Carefully clean around the impeller with a soft brush or cloth.
Note: Some cover pumps, like the ones available on PoolPartsToGo.com, are designed to make impeller access easy!
5. Test the Power Supply
If your pump is unresponsive:
-
Try a different outlet to rule out power issues.
-
Check the cord for signs of wear or damage.
-
Reset your GFCI outlet if applicable.
6. Consider the Age of the Pump
If you’ve cleaned it, checked the hose, and verified power, but it’s still slow, your pump may simply be worn out. Over time, motors lose efficiency or fail.

Final Thoughts
Most slow or clogged pool cover pumps just need a quick clean. Regular maintenance can prevent bigger issues, like a sagging pool cover or waterlogged debris. When in doubt, inspect it from the outside in. Start with the intake and work your way through the pump system.
