Why Change the Sand in Hayward S244T Pool Filter

Changing the sand in your Hayward S244T pool filter is essential for maintaining optimal pool water quality. As the filter sand becomes worn, it loses its ability to filter out impurities and contaminants from your pool water. This can result in cloudy or dirty pool water, which is not only unappealing but also potentially unsafe for swimming.

Materials Required for Changing the Sand

Before you begin changing the sand in your Hayward S244T pool filter, you will need the following materials:

- Sand filter cleaner

- Pool filter sand

- Screwdriver or wrench

- Shop vac or hose

- Bucket or container

- Gasket sealant

- Lubricant

These materials can be easily found at your local pool supply store or online.

Steps to Follow When Changing the Sand

Step 1: Turn off the pump

Before you begin changing the sand, make sure to turn off the pump and remove any electrical cords from the outlet. This will prevent accidental electrocution while working on the filter.

Step 2: Backwash the filter

Next, you will need to backwash the filter to remove any loose debris and dirt that has accumulated in the sand. Attach a hose to the backwash valve and turn the valve to the backwash position. Turn on the pump and let it run for about two minutes until the backwash water runs clear.

Step 3: Remove the sand

After backwashing, you will need to remove the old sand from the filter using a screwdriver or wrench to detach the drain plug at the bottom of the filter. Allow the sand to drain out completely, either into a bucket or directly onto the ground.

Step 4: Clean the tank

With the sand removed, it’s time to clean the inside of the filter tank. Use a sand filter cleaner to remove any remaining debris from the filter walls and laterals. Rinse the tank thoroughly with a hose.

Step 5: Add new sand

Before adding new sand, it’s essential to check the laterals and replace any that are damaged or broken. Then, pour new pool filter sand into the filter until it reaches the appropriate level. Refer to the owner’s manual for specific instructions on how much sand to add.

Step 6: Reassemble the filter

After adding the sand, it’s time to reassemble the filter. Replace the drain plug, replace the top of the filter tank, and make sure all the clamps and bolts are properly tightened. Use a gasket sealant and lubricant on any seals and o-rings to ensure a tight seal.

Step 7: Run the filter and check for leaks

Finally, turn on the pump and check for leaks around the filter. Let the pump run for a few minutes to allow the sand to settle before returning the filter to its normal operating position.

Tips for Maintaining Your Pool Filter

Here are a few tips to help you maintain your Hayward S244T pool filter:

- Backwash your filter regularly to prevent a build-up of debris and dirt in the sand.

- Check the pressure gauge and backwash when the pressure is around 10 PSI higher than normal.

- Replace damaged or worn out laterals to ensure proper filtration.

- Add a filter cleaner to the sand every few months to help maintain its effectiveness.

- Replace the sand in your filter every three to five years or as needed.


Changing the sand in your Hayward S244T pool filter is a simple process that can help maintain optimal pool water quality. With the right materials and steps, you can easily replace the old sand with new pool filter sand, ensuring your pool stays clean and clear.
