If you own a pool, you know that regular maintenance is crucial in order to keep your pool in tip-top shape. One of the most important aspects of pool maintenance is changing the filter sand in your pool filter. This is something that should be done at least once every five years in order to keep your pool water clean and clear. In this article, we will show you how to change the sand in your Hayward pool filter and provide you with some helpful tips to make the process as easy as possible.

Subheading 1: Prepare Your Pool Filter

Before you start to change the sand in your pool filter, you will need to make sure that you have all the necessary tools and supplies. In addition to new filter sand, you will also need a new pool filter O-ring and some lubricant. You will also need a bucket, screwdriver, wrench, and some towels.

Once you have all your supplies ready, you will need to shut off your pool pump and filter. This will prevent any accidents from occurring while you are changing the sand.

Subheading 2: Remove the Pool Filter

The next step is to remove your pool filter from its housing. To do this, you will first need to remove the bolts that hold the filter in place. Once the bolts are removed, you can separate the filter from the housing. Be sure to keep track of all the bolts and nuts as you will need these when it is time to put the filter back together.

Subheading 3: Remove the Sand

Now it is time to remove the old sand from your pool filter. This may require some muscle as the sand can be heavy and compacted. Begin by scooping out as much sand as you can using a bucket. Once most of the sand is removed, you can use a wet-dry vacuum to remove any remaining sand.

After you have removed all the sand from your pool filter, you will need to clean the filter thoroughly. Use a hose to spray off the inside of the filter and remove any debris that may be left inside.

Subheading 4: Add New Sand

Once your pool filter is clean, it is time to add new sand. Begin by pouring 50 pounds of pool filter sand into the filter. Be sure to use the correct type of filter sand for your filter. Then, use a plastic cup to create a depression in the center of the sand.

Subheading 5: Reassemble Your Pool Filter

Now it is time to put your pool filter back together. Begin by replacing the filter O-ring with a new one, and lubricate it with some pool lubricant. Then, place the filter into the housing and attach it with the bolts and nuts you removed earlier.

Once your pool filter is securely in place, turn your pool pump and filter back on. Allow the pool to run for several hours in order to circulate the new sand and ensure that everything is working properly.


Now that you know how to change the sand in your Hayward pool filter, you can be sure that your pool water will stay clean and clear. Be sure to follow these instructions carefully and take your time to make sure that everything is done correctly. With proper maintenance, your pool filter will last for many years and keep your pool water crystal clear.
