If you own a swimming pool, it is crucial to maintain its cleanliness and safety by ensuring that the water is always clear and free from debris. One way to achieve this is by installing a quality pool filter such as the Hayward pool filter. The Hayward filter has been designed to trap dirt and debris, ensuring that your pool water stays clear and safe. However, as you continue to use your pool, the filter will become clogged with debris, which will reduce its efficiency. To restore its efficiency, you will need to backwash the filter. In this article, we will show you how to backwash a Hayward pool filter video.

What is backwashing?

Backwashing is a process that involves reversing the flow of water through a pool filter to flush out any debris and dirt that has been trapped in the filter. When you backwash your filter, the water is forced through it in the opposite direction, which dislodges any dirt or debris that may be clogging it. This process ensures that the filter is clean and that the water in your pool is free from debris, making it safe for swimming.

Why is backwashing important?

When a pool filter becomes clogged with debris, it will not be able to filter the water effectively, leading to cloudy or green water. This can, in turn, lead to health problems as bacteria and other harmful microorganisms can thrive in stagnant water. Additionally, a clogged filter will strain your pool pump, leading to increased energy costs, and it may even cause the pump to fail. Therefore, it is essential to backwash your Hayward pool filter regularly to maintain your pool's cleanliness and safety.

Subheading 1: Preparing to backwash your Hayward pool filter

Before you start the backwashing process, you need to turn off your pool pump. This is important as it will prevent any new debris from entering the filter during the backwashing process. Once you've turned off the pump, you should locate the backwash valve on your filter. This is typically located near the filter's main control valve or on top of the filter tank.

Subheading 2: Setting up your Hayward pool filter for backwashing

Once you've located the backwash valve, you should turn it to the backwash position. This will redirect the water flow from the pool to the filter in the opposite direction, causing the debris to be flushed out of the filter. Next, you should attach a backwash hose to the waste port on the backwash valve. This hose should be long enough to reach a safe area where the dirty water can be discharged, such as a storm drain or a flower bed.

Subheading 3: Backwashing your Hayward pool filter

After setting up your filter, you can turn your pool pump back on. This will cause water to flow in the opposite direction, dislodging the dirt and debris from the filter. You should allow the pump to run for about two to three minutes or until the water in the backwash hose runs clear.

Subheading 4: Rinsing your Hayward pool filter

After backwashing, you should turn the backwash valve to the rinse position. This will direct the water flow back to the filter, flushing out any remaining debris. You should allow the pump to run for about one minute or until the water in the backwash hose runs clear.

Subheading 5: Returning your Hayward pool filter to the filter position

Once you've finished rinsing the filter, you can turn the backwash valve to the filter position. This will restore the normal water flow through the filter, and your pool pump will resume its normal operation. You should also make sure that you remove the backwash hose from the waste port and store it away safely.


Backwashing your Hayward pool filter is an essential part of maintaining your pool's cleanliness and safety. By following these simple steps, you can ensure that your filter is free from debris and working efficiently. Backwashing your filter regularly will also prolong its lifespan, save you money on energy costs, and prevent pump failures.
