How To Properly Clean And Maintain Your Pool Filter

Essential Pool Filter Maintenance Tips for a Sparkling Clean Pool

A pool filter is one of the most crucial components of your swimming pool. To keep your water sparkling clean and free of debris, regular maintenance is a must. Whether you have a sand, cartridge, or diatomaceous earth (DE) filter, knowing when to clean your filter is key. A general rule of thumb is to monitor your filter's pressure: take a reading when the filter is clean, and when the pressure rises by about 10 PSI, it's time for a cleaning.

Here’s a breakdown of how to properly clean each type of pool filter:

Sand Filter Maintenance

Backwashing your sand filter is essential to keep it working efficiently. The frequency of backwashing depends on pool usage but should be done anywhere from every few days to once a week.

Steps for Backwashing a Sand Filter:

1. Clean the Skimmers: Start by cleaning out your pool skimmers.

2. Turn Off the Pump: This is a critical step! Always turn off the pump before switching the backwash valve to prevent damage to your equipment.

3. Set the Valve to "Backwash": Turn the valve to the “backwash” setting, and then turn the pump on. Most filters have a view glass that allows you to see debris being flushed out. Let it run until the water appears clear.

4. Switch to "Rinse" or "Filter": Turn the pump off again, then switch the valve to the “rinse” or “filter” setting for about 15 seconds.

5. Repeat the Backwash Cycle: Turn the pump off, set the valve back to “backwash,” and repeat the process.

6. Final Setup: Once done, turn the pump off and set the valve to the “filter” position before turning the pump on again.

Tip: Over time, the sand in your filter gets smoother and less effective at trapping dirt particles, which means your filtration system has to run more frequently. It’s recommended to change the sand in your filter every 5 years. If you’re not familiar with plumbing, it’s best to hire a professional to replace the sand.

Cartridge Filter Maintenance

Cartridge filters are easier to maintain compared to sand filters but still require attention.

Steps for Cleaning a Cartridge Filter:

1. Turn Off the Pump: As always, turn off the pump before you begin.

2. Rinse the Cartridge: Gently rinse off any loose debris with a garden hose. Be careful not to use high-pressure water as this could force dirt deeper into the cartridge.

3. Soak the Cartridge: For a deeper clean, soak the cartridge overnight in an alkaline-based cartridge cleaner solution.

4. Rinse Again: After soaking, rinse the cartridge thoroughly to remove chemicals and any remaining debris.

Tip: Over time, your cartridge filter may lose its effectiveness. It’s a good idea to replace the cartridge every 3-5 years to maintain optimal filtration.

Diatomaceous Earth (DE) Filter Maintenance

DE filters are highly effective but require more maintenance compared to sand and cartridge filters. Regular cleaning ensures your DE filter operates efficiently.

Steps for Cleaning a DE Filter:

1. Backwash the Filter: Follow the same steps as sand filters to backwash the DE filter. However, unlike sand filters, the DE powder is removed during backwashing.

2. Clean the Filter Grids: After backwashing, remove the DE filter grids and clean them. The manufacturer’s instructions will provide specifics on how to do this properly.

3. Recoat the Filter Grids: Recharge the grids with fresh DE filter powder. Slowly add 1 pound of DE for every 10-12 square feet of filter space while the filter pump is running.

4. Check Your Owner’s Manual: Ensure you're adding the correct amount of DE, as adding too little can damage equipment or reduce filtration quality.

Tip: Once or twice a year, it’s also a good idea to remove the DE filter grids and wash them for a deeper clean.

When to Replace Your Pool Filter

Filters can wear out over time, and if yours is no longer performing as efficiently, it may be time to replace it. Most filters typically last 3-5 years depending on the type and usage.
