How to Backflush a Hayward Pool Filter


If you own a Hayward pool filter, then it is important to know how to backflush it to keep it in good working condition. By backflushing your pool filter, you can remove all the debris that has accumulated in it, which will help extend the lifespan of your filter and improve the overall quality of your pool water. In this article, we will go over the steps on how to backflush a Hayward pool filter.


What is Backflushing?


Backflushing is the process of reversing the flow of water through your pool filter to dislodge any trapped debris that has built up on the inside. When you backflush your pool filter, it forces the accumulated debris out of the filter and through the backwash valve, which will then be directed to your waste line. By doing so, your pool filter is cleaned out and ready to operate at maximum efficiency once more.


Step 1: Shut off the Pool Pump


Before you begin to backflush your Hayward pool filter, it's crucial to make sure that the pool pump is turned off. If you don't turn off the pool pump, it can lead to damage to your plumbing system, which can be expensive to repair. You can switch off the pool pump using the circuit breaker or the pump switch.


Step 2: Turn the Valve to Backwash


Locate the multiport valve on your Hayward pool filter and turn the handle to the "backwash" position. If you have a slide valve, then pull up the handle and turn it towards the backwash position. Doing this will divert the water flow, allowing you to backflush the filter.


Step 3: Turn on the Pool Pump


Once you've turned the valve to backwash, turn on the pump, and let it run for about two to three minutes. During this time, the dirty water will flow out of the waste line.


Step 4: Keep an Eye on the Backwash Water


While backwashing, keep an eye on the color of the backwash water as it flows out of the waste line. If the water is still dirty after two to three minutes of backwashing, you may need to keep backwashing for another minute or two.


Step 5: Rinse the Pool Filter


After you've completed backwashing the pool filter, it's essential to rinse the filter. Set the valve to rinse, and let the water run through the filter for approximately 30 seconds to one minute.


Step 6: Turn Off the Pump


Once you've rinsed the pool filter, turn off the pump, set the valve to its original position, and turn the pump back on. Your pool filter is now ready to function again.


Conclusion


Backflushing a Hayward pool filter is an essential maintenance step in any pool owner's routine. It ensures the optimal performance of your pool filter and helps keep your pool water clean and clear. By following the simple steps outlined above, you can keep your pool operating at maximum efficiency for as long as possible. Make sure to backwash your pool filter regularly, and always keep an eye on the quality of your pool water.
