How to replace a pump impeller
An impeller is a small but important part of a pumping system. It looks like a little three-dimensional propeller. It draws liquid, mainly water, toward it before expelling it through an outlet pipe. Impellers fall into two classes: single and double suction. Single suction impellers pull water from one side, while double suction models attract water from two sides. Impellers are used in pumps for swimming pools, jet skis, outboard motor boats, washing machines and sump pumps. They tend to need replacing when they cannot revolve due to being clogged with dirt, hair and other debris.
Remove the impeller and examine it. If it shows signs of corrosion, replace it with a new one. If it is just clogged, wash it thoroughly under a faucet.
Return the impeller to its casing and secure it.
Put the pump base back and screw it down tightly.
Put the pump back into the sump pit and reattach the outlet pipe.
Turn on the pump and see if the impeller is working. Check that the water level is decreasing.
Keep the manufacturer's instructions in a safe and accessible place.
To find the impeller, you will need to consult the instructions.
To reduce the chances of having the impeller clog again, clean out the sump basin.
Always keep a spare impeller handy in case the existing one is damaged or corroded.
Make a note of the replacement part number for the impeller and keep it safe.
Make sure your hands are dry before touching the switch and electric socket.
Remove the plug after switching off the appliance. Electricity still travels through cable, albeit at a lower charge.
To keep from receiving electric shocks, either stand on a rubber mat or wear rubber-soled shoes.
