How to Thoroughly Clean a Pool Pump Unit

A pool pump works to clear a pool of leaves and other debris which has fallen into the pool. It also helps to mix and maintain the correct chemical levels in the water. However, having a clogged and debris laden pump can seriously affect the working ability of the pump itself. This is usually manifested by a lack of power from the pump, or a pump which struggles to clean the water properly.

Replacement pumps can be quite expensive; the best option is to not only maintain the working parts of the pump by making a regular maintenance program to inspect these parts, but also to regularly clean the pump basket and the diffuser. This article will help you to thoroughly clean these parts. 

The Basket

To clean the internal basket, which collects the debris, start by placing the pump on a suitable table. You should remove the screws from the motor end of the pump. Once this section has been removed, you will be able to peer inside the unit and see the basket. Some models have metal baskets and some have plastic baskets; they do the same job. To remove the basket inside, you will need to lift (or unscrew) the lid off of the unit. Simply remove the basket and empty it. Leave to one side, as the next job is to clean the impeller.

The Impeller

The impeller is located at the opposite end of the pump motor, and can be accessed once you have pulled the diffuser off by hand. You can identify the impeller due to its spiral design. To remove the impeller, you need to secure the shaft (at the back of the motor) with one hand, while unscrewing the impeller with the other. Otherwise, the impeller will turn as you screw, and remain fastened to the motor.

Once you have the impeller off, clear the spiral design with a cloth to remove the debris. Most pool impellers have small, slit rectangles featured in the top side of the impeller; these are great places for debris such as berries or seeds to gather and clog the pump. They affect the working pressure of the pump. Pick the debris out, and clean the slots with a cloth.

Reassemble

To reassemble the pump, reverse the process you took to take it apart. As you assemble the parts back together, inspect the gaskets, rings and screws for signs of wear and tear or damage, and replace if necessary.

Depending on your location, and the kind of features (such as trees) you have surrounding your pool, you may need to clean the pump frequently. It does not take much time to take the pump apart to check for debris, so carry out your cleaning and maintenance of the pool pump as needed; this will extend the life of the parts and the pump considerably.
