How to Backwash Salt Water Pool Filter

Maintaining a clean and clear swimming pool is essential for enjoying a safe and pleasant swimming experience. One of the ways to keep the pool water clean is by using a salt water pool filter. A salt water pool filter removes impurities and contaminants from the water and keeps it crystal clear. However, to ensure the filter operates at peak performance, it is necessary to perform routine backwashing. In this article, we will discuss how to backwash a salt water pool filter.

Understanding the basics of backwashing a salt water pool filter

Before you start backwashing the filter, it is crucial to understand what it entails. In simple terms, backwashing is a process where you reverse the flow of water through the filter to remove the accumulated dirt and debris. As the water flows backward, it pushes the dirt and debris out of the filter and into the waste line or drain. Backwashing should be done when the pressure gauge reading on the filter rises to about 8-10 psi above normal.

Step-by-step guide on how to backwash a salt water pool filter

1. Turn off the pump

Before you start the backwashing process, it is essential to turn off the pool pump.

2. Locate the backwash valve

The next step is to locate the backwash valve on the filter. The valve could be located on the top or the side of the filter.

3. Connect the backwash hose

Connect the backwash hose to the waste line or the drain. Ensure that the hose is securely attached to prevent any leaks.

4. Turn on the pump

With the hose in place, turn on the pool pump and let it run for about two to three minutes to flush out any debris.

5. Check the sight glass

While the pump is running, check the sight glass on the filter. The sight glass will give you an indication of when the water has cleared of debris.

6. Turn off the pump

Once the water in the sight glass is clear, turn off the pump and the filter.

7. Adjust the valve

After the pump and the filter have been turned off, adjust the valve back to the filter position.

8. Rinse the filter

After adjusting the valve, turn on the pump for about 30 seconds to rinse the filter.

9. Turn off the pump

Finally, turn off the pump, disconnect the backwash hose and replace the filter cover.

Tips for backwashing a salt water pool filter

1. Backwash your filter only when the pressure gauge reading rises to 8-10 psi above normal.

2. Always turn off the pump before you start the backwashing process.

3. Make sure that the backwash hose is securely attached to the waste line or drain to prevent any leaks.

4. Check the sight glass to determine when the water has cleared of debris before turning off the pump.

5. Rinse the filter for at least 30 seconds after backwashing to remove any remaining debris.

Conclusion

Backwashing is a critical process that ensures that your salt water pool filter operates at peak performance. By following the steps outlined above, you can backwash your filter safely and effectively. Remember, proper pool maintenance is essential for enjoying a healthy and clean swimming pool experience.
