How to Use Backwash on Pool Filter


Having a clean and well-maintained pool is one of the basic essentials of owning a swimming pool. The health and safety of swimmers depends on the efficiency of the pool filter in keeping the water clear and free of debris.


But how do you keep the pool filter functioning optimally? This is where backwashing comes in. Backwashing is a process you can use to clean your pool filter and remove any dirt and debris that has accumulated.


In this article, we will guide you through the process of using backwash on your pool filter. We will discuss the importance of backwashing, the steps involved, and tips to ensure you get the best results.


Why Backwash Your Pool Filter?


Over time, your pool filter will collect dirt and debris such as leaves, hair, and dirt. If left unchecked, this will reduce the filter’s efficiency in cleaning the water. Backwashing your pool filter is a vital process that helps to remove the debris and dirt collected in the pool filter.


Backwashing helps to maintain the filter’s efficiency, prolong its lifespan, and improve the quality of the pool water.


How to Backwash Your Pool Filter


Now that you understand the significance of backwashing, it’s time to take action. The following steps will guide you on how to backwash your pool filter like a pro.


Step One: Turn Off Your Pump


Turn off your pump before you start the backwashing process. You don’t want to run your pump while the pool filter valve or multiport valve is in transition mode. This will cause the pool filter to break or malfunction.


Step Two: Turn the Valve to the “Backwash” Position


Turn the valve on your pool filter to the "backwash" position. This is typically located on the multiport valve, but you need to check your filter user manual for the full details.


Step Three: Start the Pump


After switching to the backwash position, you can turn on the pump. The water flow direction in the pool will now be reversed, and the dirt and debris will be pushed out of the pool filter.


Step Four: Monitor the Water Flow


The water flow in the backwash position should run with considerable force out the waste line. Observe the outflow of water and check the pressure gauge to monitor the process. When the backwash water is clear, it signifies that the pool filter is clean, and you can then proceed to stop the backwash process.


Step Five: Rinse Your Pool Filter


To remove any residual dirt or debris, rinse your pool filter by positioning the valve to the "rinse" position. Run water through the filter for about 30 to 60 seconds to get rid of the remaining dirt.


Step Six: Restore the Valve Position


After rinsing, turn the valve position to the ‘filter’ setting to restore the normal water flow and operation.


Backwash Tips


Here are some useful tips to follow whenever you backwash your pool filter:


Perform Backwash Frequently: The frequency of backwashing depends on the size of the pool and the usage frequency. It is essential to backwash the pool filter weekly to maintain its efficacy.


Check Filter Pressure: Always check the filter pressure before and after backwashing your filter. If the filter pressure is consistently high, it’s time to clean the filter.


Keep the Pool Skimmer Basket Clean: One of the ways to prevent dirt and debris from entering your pool filter is to keep the skimmer basket clean.


Replacing Filter Sand: If you have a sand filter, you need to replace the filter sand every 3-5 years.


Clean the Filter Pump Strainer: Ensure that you clean the pool pump strainer regularly to keep it clog-free.


Conclusion


Backwashing your pool filter is critical to maintaining clean pool water. It’s a straightforward process that can help restore and maintain the filter's efficiency. By following the tips and steps we have provided, you can keep your pool filter clean, prolong its lifespan and ensure that your pool remains a healthy and enjoyable environment for swimmers.
