How cartridge filters work and how to clean them
Getting to know your cartridge filter
Your swimming pool pump contains more than one level of filtration devices. It is designed in this manner for a couple of reasons. Of course, the pump is made to keep your pool clean and sanitary through constant filtration, chlorination and circulation. In addition, the filtration systems included with the pump keep the whole mechanism itself from clogging up and burning out or becoming damaged in some other way. Since the filtration does play such an important role, it is equally important for you to understand how it works and how to maintain it.
How cartridge filters work
Your swimming pool pump contains a cartridge filter. This filter does the same job as an air conditioner filter in your home, an oil filter in your car, or an air filter in the vacuum cleaner. It is designed to catch all the minute little particles of debris that come in with the swimming pool water. This way, the debris is not sent back into the pool and it does not make it to the pump where it can cause clogs. This cartridge filter plays an important role, and because of its role, it can become quite clogged itself.
It is very easy for you to know when the filter needs to be cleaned though. Right on top of it is a pressure gauge. This will let you know when the filter is too clogged and the water pressure is too high. When you first start up your swimming pool pump, check that pressure gauge and get a good base reading. After that, you can use the base reading to determine when the filter needs to be cleaned. Once the pressure goes up ten pounds higher than the original reading, you will know it is time to clean.
Cleaning your cartridge filter is simple. All you need is a water hose and the instruction manual for taking the filter apart. Once it is cleaned, you can replace it and your pool pump will continue to work correctly, keeping your swimming pool clean and clear.
