How to Change Sand in Pool Filter Hayward: A Step-by-Step Guide

If you have a pool, then you know how important it is to maintain it so it stays clean and safe for everyone to swim in. One of the crucial parts of your pool's maintenance is cleaning your pool filter, and if you have a Hayward sand filter, this is what this article will be about.

If you need to change the sand in your pool filter, then you've come to the right place. This guide will walk you through, step-by-step, on how to do it so you can maintain your pool's upkeep.


1. Gather Tools and Materials

2. Turn Off Your Pool's Pump

3. Disconnect Your Filter

4. Remove Old Sand and Clean Filter

5. Add New Sand and Reconnect Filter

1. Gather Tools and Materials

Before you begin, you'll need to gather all the necessary tools and materials for the project. To change the sand in your Hayward pool filter, you'll need:

- A pool filter sand removal tool or a wet-dry vacuum with a hose

- A garden hose

- A Phillips head screwdriver

- A new sand filter

- Lubricant (optional)

2. Turn Off Your Pool's Pump

Next, you'll want to turn off your pool's pump. This is an essential step because you don't want the water to keep flowing while you're changing out the sand. Doing so could cause a lot of problems, including damaging the filter and its components.

3. Disconnect Your Filter

After shutting off your pool's pump, you'll want to disconnect your filter. To do this:

- Use a Phillips head screwdriver to remove the screws that attach the top of your filter to the base.

- Remove the top of the filter.

- Gently lift the filter's "spider gasket" and push it down so it lays flat on the top of the sand. This will prevent sand from getting into the "spider tube."

- Next, you'll want to remove the "lateral assembly" (which holds the sand) by gently lifting it and pulling it out of the filter.

4. Remove Old Sand and Clean Filter

With the lateral assembly removed, you can now remove the old sand. Place the sand removal tool or the hose into the filter, and siphon out the old sand into a container. Be sure not to let sand enter the filter's plumbing.

Once the old sand is removed, you can then clean the filter with your garden hose. Be sure to remove any debris or build-up in the lateral assembly and the filter's interior. If needed, you can also replace the "spider gasket" at this stage.

5. Add New Sand and Reconnect Filter

You've made it to the final step! Once you've thoroughly cleaned the filter, it's time to add new sand. Be sure to read the manufacturer's label to know how much sand is required for your filter size.

Once you've added the new sand, you'll need to lubricate the "spider gasket" and reattach the lateral assembly back into the filter. Then, you can reattach the top of your filter with the screws you removed earlier.

Now that the filter is reconnected and new sand is in, you're almost done! Make sure you turn the pump back on and check for any leaks.


Changing sand in a pool filter like Hayward may seem like a daunting task at first, but this guide has provided you with a step-by-step process to guide you through. By following these tips and being patient through this process, you will surely enjoy the benefits of having clean water in your pool.
