Swimming pools are a must-have for any household that desires a private and entertaining outdoor space. It is essential to maintain and clean them regularly to maximize their longevity and prevent water-borne diseases. To accomplish this, you need to backwash your above ground pool filter as part of your routine pool maintenance.

Backwashing pool filters solve issues like chemicals build-up, pool sludge, and dirt, which affect the cleanliness of the water. This article provides a five-step guide on how to backwash pool filter and some tips to keep in mind. Let's dive in!

What is Backwashing?

Backwashing is a process of reversing the flow of water to clean the pool filter of impurities that have collected in its pipes. It involves removing and flushing out accumulated dirt and debris from the filter's media.

Why Backwash Your Pool Filter?

Backwashing your pool filter is a crucial part of maintaining your pool's hygiene. It helps to remove impurities such as dirt, debris, and bacteria accumulated in the filter system to prevent pool water from becoming cloudy and discolored. Backwashing does not completely clean the filter media, but it significantly improves its efficiency.

When is Backwashing Necessary?

Backwashing frequency highly depends on the pool's usage level and types of media used in the filter system. The general rule of thumb is to backwash the filter when the pool's pressure gauge reads a three to five pounds increase from normal operating pressure. If you observe any indications of impurities in the pool water, like cloudy water, a more frequent backwash schedule is necessary.

Step-by-Step Guide on How to Backwash Pool Filter

1. Turn off the pool pump. Safety is always essential, and turning off the pump prevents any accidents while performing maintenance.

2. Adjust the pool filter valve. There are two filter valve options; the push-pull valve and the multiport valve. Set the valve to the backwash position to start the process.

3. Clean the pool filter. After selecting the backwash position, turn the pool pump back on and run it for 3-5 minutes. Ensure that the waste hose is pointed in the right direction, away from the pool area, to avoid re-contamination.

4. Rinse the filter media. After the backwash process, set the filter valve to the rinse position and run the pump for 1 minute to flush out any remaining impurities.

5. Return the filter valve to normal position. Turn off the pump and return the filter valve to its regular position. You have now completed the backwash process.

Tips to Keep in Mind when Backwashing the Pool Filter

1. Ensure the pool pump is turned off before making any maintenance changes.

2. Always wear protective gear, such as gloves and safety goggles, to prevent accidents.

3. Avoid overwashing to prevent damaging the filtration system.

4. Reduce water usage by reusing the backwash water by watering plants around your compound.

5. Repeated backwashing of a sand filter can result in sand loss and increase the need for refilling new sand.

Conclusion

Backwashing your pool filter is a necessary step in pool maintenance. It's a straightforward process that involves reversing the flow of water to flush out accumulated dirt and debris. Frequent backwashing keeps pool water sparkling clean and prolongs the life of your filter system. Remember to take precautionary measures and follow the recommended steps when backwashing your pool filter. Happy swimming!
