When to Recirculate Pool Filter: A Complete Guide

As a pool owner, ensuring that your pool is in its best condition is very important. One of the things that you need to do regularly is to maintain your pool filter. While there are different types of pool filters, one common question that most pool owners ask is when to recirculate the pool filter. In this article, we will discuss everything you need to know about recirculating your pool filter.

What is Pool Filter Recirculation?

Recirculating your pool filter is the process of running the filter pump without actually running the water through the filter. It is usually done to increase the water flow to clear or remove debris that has been stuck in the pool filter. During recirculation, the water is redirected back to the pool instead of going through the filter. This is typically done for a short time and should not be a regular maintenance practice.

When Should You Recirculate your Pool Filter?

Here are some situations when you should consider recirculating your pool filter:

1. Clearing Debris: If you have noticed that debris, such as leaves or small twigs, have blocked the pool filter's skimmer, you can opt to recirculate the pool filter. This will help to clear the debris without harming the filter system.

2. Low Water Flow: If you have noticed a sudden decrease in water flow from your filter, it may be because of clogging in the filter system. Recirculating your pool filter can help clear the obstruction and restore normal water flow.

3. After Cleaning Cartridges: If you have cleaned the pool filter cartridges, you can opt to perform a recirculation cycle to ensure that the filter's working properly before returning to regular filtering mode.

4. Before Starting Up: If you have not used your pool for an extended period, it is advisable to recirculate the pool filter before starting it up. This will help remove any debris or dust that has settled in the filter during the period of inactivity.

5. To Adjust the Pool Chemistry: If you need to adjust your pool chemistry, recirculating the pool filter can help distribute the chemicals appropriately.

How to Recirculate your Pool Filter

Recirculating your pool filter is a straightforward process. Here are the steps to take:

1. Ensure Everything is Switched Off: Before beginning the recirculation process, make sure that the pool filter, heater, and pump are all switched off.

2. Set the Filter Valve: Move the filter valve to the recirculate position. This will allow water to circulate from the pool and return it back to the pool, without passing through the filter.

3. Turn on the Pump: Turn on the pool pump and allow it to run for about 15 minutes or until the water runs clear. This will help remove any debris or dirt present in the filter.

4. Reverse the Process: Move the pool filter's valve back to its original position and turn on the pump to start the filtering process.

Conclusion

Recirculating your pool filter is a simple process that will help keep your pool in the best condition. Remember that recirculation should only be performed when necessary, and it should never replace regular filter maintenance. Be sure to keep a schedule for regular filter cleaning and maintenance to ensure optimal performance.
