As spring and warmer temperatures are just around the corner, now is the best time to start thinking about ways to prep your swimming pool for the upcoming season. With that being said, we want to spend the next few weeks discussing different ways to do that. First, is your pool filter ready to handle the increased load? Whether you own a DE, Cartridge, or Sand Filter we can start with this because a clean filter leads to a clean swimming pool.

Do you own a cartridge filter? If so, let’s continue our discussion with this popular filter….

Is the pressure reaching the cleaning stage (otherwise known as, “Is your filter dirty”)? Have you ever cleaned this type of filter by yourself? At Clark County Pool & Lawn we know cartridge filters are popular but it’s important to know that when the gauge reaches “dirty” that you properly clean them!

How To Clean A Cartridge Filter

One of the biggest reasons why homeowners choose cartridge filters is the lack of continuous maintenance it requires. Unlike sand or DE filter that needs to be backwashed regularly, a cartridge filter only needs to be cleaned a few times per year. When a cartridge filter needs to be cleaned, it can, however, be a tedious process but we want to support you with that. So, if your pressure gauge is 10 – 12PSI above the starting pressure or it reads “Dirty” it’s now time to begin the process. At Clark County Pool & Lawn, we not only offer weekly service but this service also and wanted to give you the step by step process for those that want to do it at home. Please keep in mind, cartridge filters are great for those that are water conscious but to keep it functioning properly you must keep it clean!

The following is a step by step process on how to clean a cartridge filter:

  1. Completely turn off all your filtration equipment and make sure the pool timer is not set to automatically turn on during your cleaning process. If you have access to the breaker box turning it off is also a good idea.
  2. Slowly bleed the air from the filter by opening up the air relief valve. You can typically find this valve on the top of your filter.
  3. Open up the drain plug to let all the water out of the filter.
  4. Remove the tension clamp that holds the filter together. Each brand may have their own release mechanism, so make sure to follow the manufacturer’s instructions and have the proper tools to do it.
  5. There may be some part holding these cartridges in place. If this mechanism is present, it must be removed before taking your cartridge filters out and stored in a safe and dry place.
  6. Carefully and slowly remove all the cartridge filters and set them aside. It is important to inspect each cartridge for cracks, tears or other any other visual damage. If damage has occurred you will need to replace it as soon as possible.
  7. Use a garden hose to rinse debris from between the pleats. Make sure to run the water and clean the inside of the filter, as well.
  8. After they have been rinsed off and no damage is present you will need a large bucket or trash can for the next step. This step will help to remove lotions, oils, and sunscreen. You will need to soak them in a filter cleaner or detergent. This process should take about 8 -10 hours and can be left overnight if you choose. If you use a detergent only use 1 cup for every 5 gallons of water. Do not use more than what is recommended. This is one of those instances where more isn’t better because it can be difficult to remove the soap!
  9. After the soak has been completed make sure to hose them off again extremely well to remove the cleaning agent.
  10. Place cartridges back in the filter, replace the lid and clamp. Make sure clamp is tight and on well before you move on to step #11.
  11. Turn on the system and open up air relief valve to remove all excess air.
  12. Take note of new filter pressure and set clean and dirty numbers to help remind you when it’s time to do this process again. This can be done on filters with newer gauges. If you don’t have a dirty setting take note of initial pressure.
