How to Backwash a Jandy Pool Filter

Jandy pool filters can be a great option for homeowners who want to keep their pools clean and clear. However, even the best pool filters need to be cleaned and maintained regularly to ensure they work at maximum efficiency. Backwashing is an essential part of this maintenance process, as it helps to remove built-up debris and contaminants that can clog the filter and reduce its effectiveness. In this article, we'll go over everything you need to know about how to backwash a Jandy pool filter.

Why Backwash?

Jandy pool filters, like other types of pool filters, work to remove debris and contaminants from pool water. As the filter traps more and more of this debris over time, it becomes clogged and less effective at its job. Backwashing is the process of cleaning the filter by reversing the flow of water through it. This helps to dislodge built-up debris and flush it out of the filter, so it can continue to operate effectively. If you don't backwash your Jandy pool filter regularly, it can become clogged and stop working correctly, leading to cloudy, dirty water and potentially costly repairs.

When to Backwash?

The frequency with which you should backwash your Jandy pool filter depends on a variety of factors, including the size of your pool, how often it's used, and the type of filter you have. In general, most pool experts recommend backwashing your filter every few weeks, though this can vary.

One helpful tip is to keep an eye on your filter's pressure gauge. As the filter becomes more clogged with debris, the pressure in your pool's plumbing system will increase, and the gauge will indicate this. When the gauge's reading is 8-10 psi higher than its normal reading, it's time to backwash the filter.

How to Backwash a Jandy Pool Filter

Step 1: Turn off the filter and pool pump.

Before you begin, make sure the filter and pool pump are turned off. This will ensure that no water flows through the system and that you can safely access and manipulate the filter.

Step 2: Turn the multiport valve to "backwash."

Next, turn the multiport valve located on the top of your Jandy pool filter to the "backwash" setting. This will redirect the water flow through the filter and out of the waste line.

Step 3: Turn on the pump.

Once you've set the multiport valve to "backwash," turn on the pool pump. This will begin the backwashing process, and you'll begin to see the dirty water being flushed out of the system.

Step 4: Run the pump until the water runs clear.

Continue to run the pump until the water being discharged from the waste line runs clear. This may take a few minutes to achieve, depending on the level of debris in your filter.

Step 5: Turn off the pump.

Once the water runs clear, turn off the pool pump and turn the multiport valve back to its original position.

Step 6: Turn on the pump and rinse the filter.

After you've switched the multiport valve back to its original position, turn on the pool pump again and run it for a few minutes. This will rinse out any remaining debris from the filter and ensure it's clean.

Conclusion

Backwashing your Jandy pool filter is an essential part of keeping your pool clean and clear. By following these simple steps, you can keep your pool filter working at maximum efficiency and avoid costly repairs down the line. Remember to backwash your filter every few weeks or as needed, and keep an eye on the pressure gauge to ensure everything is running smoothly. Taking care of your pool filter will help ensure you can enjoy a beautiful and healthy pool all season long.
