Maintaining a sparkling clean pool doesn’t just involve removing leaves and debris; ensuring your pool filter is in optimal condition is essential for a clear and healthy swimming environment. Here’s a comprehensive guide to cleaning different types of pool filters:

 

Determining Your Filter Type

Before diving into the cleaning process, it’s crucial to determine what type of filter you have. Each filter type has distinct maintenance requirements. The easiest way to identify your filter is by checking the label on its side.

 

1. Diatomaceous Earth (D.E.) Filter:

Cleaning Method: Backwashing.

Step-by-Step Cleaning Process:

  1. Ensure the pump is off before moving the backwash valve.
  2. Turn off the pump.
  3. Set the valve to backwash mode.
  4. Turn on the pump and let it run for about 1 minute or until the discharge water appears clear.
  5. Turn off the pump.
  6. Reset the valve to its standard position and turn on the pump.
  7. For a thorough clean, you can repeat these steps.
  8. Final Step: Add DE powder to the skimmer while the pump runs. Use 4 one-pound DE scoops for a “Pentair 48 SQ FT Filter” and 6 for a “Pentair 60 SQ FT Filter”. Alternatively, a 32 oz cup can serve as a one-pound DE scoop.

Additional Maintenance:  Annually dismantle and deep clean the filter. This helps in inspecting internal elements and ensures maximum efficiency. – Every 2-5 years, consider replacing the internal filter grids.

 

2. Cartridge Filters:

Cleaning Method: Manual cleaning.

Step-by-Step Cleaning Process:

  1. Switch off the pump.
  2. Detach the upper part of the filter canister and extract the cartridge elements.
  3. Thoroughly spray the cartridge elements until they’re clean, then put them back.
  4. Switch on the pump and release the air via the air relief valve.

Additional Maintenance: Every 2-5 years, think about replacing the internal cartridge elements.

 

3. Sand Filters:

Cleaning Method: Backwashing.

Step-by-Step Cleaning Process:

  1. Like with the D.E. filter, never adjust the backwash valve while the pump operates.
  2. Turn off the pump.
  3. Set the valve to backwash.
  4. Switch on the pump and let it run for 1-3 minutes or until you observe clear water.
  5. Turn off the pump, adjust the valve back to the filter setting, then turn on the pump.
  6. Open the air relief valve to release any trapped air.

Additional Maintenance:

– Every 3-5 years (or annually for painted pools), consider replacing or examining the sand.

– Whenever you remove the sand, inspect filter components like laterals for potential damages.
