When Do You Use Recirculate on Pool Filter?


A pool filter is an essential part of any pool system, and it works by removing impurities and debris from the water. One of the functions of a pool filter is to recirculate water back into the pool. But when should you use the recirculate function? In this article, we will go over what recirculate is, when to use it, and important considerations to keep in mind.


What is Recirculate?


Recirculate is a setting on your pool filter that allows water to bypass the filter system and recirculate back into the pool. Essentially, it is like creating a loop where the water will not be filtered, but instead, it will circulate back into the pool.


When to Use Recirculate?


1. When Sucking in Air: If you notice that the pool filter is sucking in air and creating an air bubble, it may be time to use the recirculate function. This problem can occur if there is too much air inside the pump, or if there is a clog in the suction lines. Using the recirculate function can help work out this air, which can prevent damage to your pool pump.


2. If There is a Clog: If your pool filter is clogged or dirty, it is best to use the recirculate function temporarily while you address the issue. A filter that is clogged will not work effectively, and the recirculate function can help you avoid a sudden pressure change that can damage the system.


3. When Adding Chemicals: In some cases, when you add chemicals to your pool, it can cause the water to become cloudy. This can make it difficult for the pool filter to work effectively. This is where the recirculate function can come in handy. By temporarily using the recirculate function, you can help circulate the water and distribute the chemicals properly.


4. To Heat Up the Pool: If you want to heat up your pool quickly, the recirculate function can help you reach that goal. Because the water is not being filtered, it is allowed to circulate more quickly through the pool, which can help your heater work more effectively.


5. To Test Chemicals: If you have recently added chemicals to your pool or are trying to test the water for pH levels or chlorine levels, the recirculate function can help provide a more accurate reading. By using the recirculate function, you can help distribute the chemicals equally throughout the pool.


Considerations When Using Recirculate


1. Use It Temporarily: While the recirculate function can be helpful for a variety of reasons, it is not something you should use all the time. Recirculating unfiltered water for extended periods can lead to poor water quality and hygiene.


2. Check for Air Leaks: If you notice that the pool filter is sucking in air, using the recirculate function may help in the immediate moment, but it is important to investigate the root problem. Check for air leaks in the system, which could be causing the issue.


3. Clean the Filter: If you are using the recirculate function because your pool filter is dirty or clogged, don't forget to clean the filter as soon as possible. This will help improve the overall water quality and prevent damage to your pool pump.


4. Monitor Chemical Levels: If you are using the recirculate function to help distribute chemicals, it is important to monitor the levels and retest the water once the function has been turned off.


5. Follow Manufacturer Guidelines: Always follow the manufacturer's instructions when using the recirculate function or any other function on your pool filter. This will help you avoid damaging the pump or creating poor water quality.


In conclusion, the recirculate function on your pool filter can be a helpful tool in certain situations. Whether you need to get rid of air bubbles, distribute chemicals, or heat up the pool, the recirculate function can help you quickly reach your goal. However, it is important to use it temporarily and follow the manufacturer's guidelines to avoid any costly damages or poor water quality.
