Steps for Properly Cleaning Pool Filters: Your Guide to Maintenance and Efficiency

Understanding Pool Filter Types

When designing a pool’s filtration system, one must consider the three main types of pool filters: cartridge, sand, and diatomaceous earth (DE). Each filter varies in its operation, maintenance requirements, and level of filtration.

Cartridge Filters utilize a fine porous material that traps debris as water flows through. These filters are known for their ease of maintenance. When the filter becomes dirty, pool owners simply need to remove the cartridge and rinse it with a hose. They are also known for their energy efficiency.

Maintenance: Rinse regularly, replace every 1-3 years.
Filtration Level: High; can filter particles as small as 10 to 15 micrometers.

Sand Filters have been a popular choice for decades. They contain a bed of special-grade sand that captures impurities as water passes through. Over time, the sand needs backwashing to clear out the accumulated debris.

Maintenance: Backwash regularly, replace sand every 5-7 years.
Filtration Level: Moderate; can filter particles down to about 20 to 40 micrometers.

Lastly, DE Filters offer the finest level of filtration by using diatomaceous earth powder to coat the internal grid elements. This powder acts like a sponge, catching even the smallest particulates.

Maintenance: Backwash and replenish DE powder regularly, clean grids annually.
Filtration Level: High; can filter particles as small as 2 to 5 micrometers.

Choosing the right pool filter depends on the desired maintenance level and the clarity required for the pool water. Each filter type contributes to a comprehensive pool maintenance program, ensuring a clean and inviting swimming environment.

Routine Maintenance and Cleaning

Proper care of pool filters ensures that pool water remains clean and the filtration system operates efficiently. Regular maintenance is crucial to extend the lifespan of the filter and maintain water quality.

Cartridge Filter Maintenance

Cartridge filters require regular checks and cleaning to prevent clogs and maintain water clarity. Inspect the pressure gauge regularly; a psi increase of 8-10 over the starting pressure indicates it’s time to clean the filter.

Turn off the pool pump and open the air relief valve to release pressure.
Remove the filter cartridge from the housing.
Rinse the cartridge with a garden hose to remove loose debris.
For a deeper clean, use a filter cleaner solution designed for cartridge filters.
Rinse thoroughly and replace the cartridge, making sure all O-rings are intact.
After reassembling, turn the pool pump back on and close the air relief valve once water starts to spray out.

Check for signs of wear or damage during cleaning, and replace the filter cartridge as needed to ensure optimal performance.

Sand Filter Care

Maintenance of sand filters involves backwashing, which reverses the flow of water to clean out trapped debris.

Monitor the pressure gauge for a 5-7 psi increase over the clean starting pressure.
To backwash, turn off the pump and set the valve to ‘Backwash’.
Turn on the pump and let the water run through the backwash hose until it appears clear.
Shut off the pump, set the valve back to ‘Filter’, and turn the pump back on.

Twice a year, the sand filter should be chemically cleaned with a sand filter cleaner to remove oils and deeply lodged debris. Ensure all chemicals are thoroughly rinsed during the backwash before resuming normal operation.

Diatomaceous Earth Filter Upkeep

DE filters provide exceptional filtration and require similar maintenance to sand filters, including periodic backwashing.

When the pressure gauge shows an increase of 5-10 psi, start the backwashing process.
After backwashing, add fresh diatomaceous earth to the skimmer as per the manufacturer’s recommendations.
Inspect the internal grids for damage or tears; replace if necessary.

Periodic disassembly and thorough internal cleaning are recommended at least once a year for DE filters to maintain their efficiency. Always adhere to the manufacturer’s instructions for proper care and maintenance.

Deep Cleaning Processes

Performing a deep clean of your pool’s filter system is crucial for maintaining optimal water quality and equipment functionality. This requires targeted treatments for each filter type, using specific cleaning agents and methods.

Thorough Cartridge Filter Cleaning

Cartridge pool filters trap dirt and debris efficiently, but over time they need a deep clean. Firstly, remove the cartridge from the filter housing and rinse off loose materials with a hose. Prepare a solution of commercial filter cleaning solution or diluted muriatic acid. Submerge the cartridge in this solution for at least 12 hours to break down oil and algae residues; rinse thoroughly afterward. Exercise safety measures by using gloves and eye protection during this process.

Comprehensive Sand Filter Cleaning

For sand pool filters, a deep cleaning extends the life of the sand and ensures better filtration. Start by backwashing the filter to clear out accumulated debris. After backwashing, turn off the pump and drain the filter. Add a commercial sand filter cleaner or a solution that includes bleach to the filter following the manufacturer’s instructions. This targets stubborn debris, algae, and bacteria. Allow the solution to sit for the time specified, then backwash the filter again until the waste water runs clear.

Intensive DE Filter Cleaning

DE pool filters require meticulous care during deep cleaning. After backwashing, remove the filter grids or fingers and hose off loose diatomaceous earth and dirt. Similar to cartridge filters, prepare a mixture of filter cleaning solution or a vinegar and water solution. Soak the items long enough to dissolve oils and grit. Algae and fine particles are particularly persistent in DE filters; therefore, a thorough soak and rinse are imperative. Before reassembling, coat the grids or fingers with fresh DE powder to ensure optimal performance.

Troubleshooting and Replacing Pool Filters
