How to Add Sand to Hayward Pool Filter

If you're a pool owner, you know how important it is to keep your pool clean and healthy for swimming. One of the key elements to maintaining that cleanliness is the pool filter. The sand filter is one of the most popular and cost-effective filters on the market, and the Hayward brand is known for making quality sand filters that are easy to install and maintain.

If you need to add sand to your Hayward pool filter, don't worry. With just a few simple steps, you can have your filter up and running smoothly again. In this article, we'll take you through the process of adding sand to your Hayward pool filter, step by step.

Why Should You Add Sand to Your Hayward Pool Filter?

Over time, the sand in your pool filter can become worn down or contaminated with debris. As a result, your filter won't be able to clean your pool as effectively as it should, leading to cloudy water and potentially harmful bacteria growth. By adding new sand to your filter, you'll improve its ability to capture and filter out unwanted particles, improving the overall cleanliness and safety of your pool.

What You'll Need:

- Hayward pool filter

- Sand (make sure to purchase sand specifically designed for pool filters)

- A wrench or pliers

- A pressure gauge

Step 1: Turn off the pump

Before you begin adding sand to your Hayward pool filter, make sure your pump is turned off to avoid any accidents or injury.

Step 2: Remove the old sand

Using a wrench or pliers, unscrew the drain cap on the filter and let the old sand drain out. Once it's empty, rinse the interior of the filter chamber with a high-pressure hose or water blaster to remove any lingering debris or grime.

Step 3: Add the new sand

Fill the filter halfway with water to stabilize the outlet and then add the new sand through the opening. Make sure you're using sand specifically designed for pool filters and the right amount to avoid overloading your filter. You can find out the correct amount of sand required for your Hayward pool filter in the manufacturer's instructions.

Step 4: Smooth out the sand

Once you've added the sand, use a straight object like a broom handle to level and smooth out the sand bed.

Step 5: Reattach the drain cap

Once you've finished smoothing out the sand bed, replace the drain cap onto the filter.

Step 6: Check the pressure gauge

Before restarting the pump, check the pressure gauge to make sure it's in the appropriate range for your filter. If the pressure gauge is too high, it's an indicator of dirt and debris buildup in the filter, and it's time to backwash the filter.

Step 7: Restart the pump

Finally, it's time to restart the pump and enjoy your newly cleaned pool. Make sure you're checking the pressure gauge regularly to ensure the filter is functioning optimally and backwash the filter as required.


With just a few straightforward steps, you can add sand to your Hayward pool filter quickly and easily. Ensuring your pool filter is functioning at its best is critical to maintaining a clean and safe swimming pool. By following these simple steps, you'll be able to enjoy your pool's crystal-clear water all summer long.
