If your pool pump is acting sluggish it may simply be a build-up of debris inside the impeller. Cleaning it is simple if you have the know-how.
Step 1 - Check the Impeller
You can check the impeller for clogs by opening the clear cover that is on the strainer basket. Then place your garden hose into the basket and turn it on high. The water should disappear immediately. If it does not, you may have a clog.
Step 2 - Turn off the Power to the Pump
Before actually removing the clog from your pool pump impeller you will need to turn off the power to it. Remove the basket and use a finger to reach into the hole behind the basket to feel for any debris. If it is clogged, go to step 3.
Step 3 - Disconnect the Pump and Motor
Disconnect the pump and motor from the plumbing. Depending upon the make and model of your pool pump you may be able to skip this step. The motor usually just slides away from the pump.
Step 4 - Remove the Plastic Cover
Take the pump apart by removing the plastic cover over the motor. This cover generally has several small screws holding it on.
Step 5 - Remove and Clean the Impeller
Once the cover is removed you will easily be able to see the clog in the pool pump impeller. Just use your fingers or a coat hanger to clean it out.
Step 6 - Clean
Put everything back together. Once you have it cleaned out you can put the cover back on and put it all back together. Problem solved.
