Are you looking to maintain your Hayward pool filter and wondering how much sand goes in it? Having the right amount of sand in your pool filter is crucial for its effective functioning. In this article, we will take a look at how much sand goes in a Hayward pool filter and offer some additional tips for proper pool maintenance.

Understanding Pool Filters

Pool filters play a crucial role in keeping your pool clean and safe for swimmers. They work by removing dirt, debris, and other contaminants from the water before it is circulated back into the pool. There are three main types of pool filters: sand, cartridge, and diatomaceous earth (DE). Each type has its own unique advantages and disadvantages, but sand filters are one of the most popular types.

Why Use Sand Filters?

Sand filters are popular for several reasons. They are relatively easy to maintain and are known for their durability. They can often last for several years before requiring replacement. In addition, sand filters are very effective at removing debris and contaminants from water. They work by forcing water through a bed of sand, which traps dirt and other debris. The clean water is then returned to the pool.

How Much Sand Goes In A Hayward Pool Filter?

The amount of sand that goes into a Hayward pool filter will depend on the size of the filter. A typical Hayward sand filter will have a capacity of between 200 and 600 pounds of sand. The amount of sand you need will also depend on the size of your pool. As a general rule of thumb, you should have 1 pound of sand per square foot of pool area. For example, if you have a 20,000-gallon pool with an area of 400 square feet, you will need around 400 pounds of sand.

Installing Sand In Your Hayward Pool Filter

Installing sand in your Hayward pool filter is a relatively easy process that you can do yourself. Follow these steps to install sand in your pool filter:

Step 1: Turn off the pool pump and drain the water from the filter.

Step 2: Remove the filter clamp band or other connectors that hold the filter together.

Step 3: Remove the old sand from the filter.

Step 4: Rinse the filter and internal components to remove any debris and dirt.

Step 5: Pour the new sand into the filter. Be sure to use the recommended amount of sand for your filter size.

Step 6: Reassemble the filter components and reconnect the filter to the pump and pool.

Maintaining Your Hayward Pool Filter

Once you have installed sand in your Hayward pool filter, you will need to perform regular maintenance to ensure it continues to function effectively. Here are a few tips for maintaining your Hayward pool filter:

1. Backwash Regularly

Backwashing is the process of cleaning the sand in your filter by reversing the flow of water. This helps to remove any debris and dirt that has been trapped in the sand. You should backwash your pool filter at least once a week or whenever the pressure gauge reaches 10 psi above the standard operating pressure.

2. Check The Sand Level

Over time, the sand in your pool filter can become compacted, reducing its effectiveness. You should check the sand level in your filter at least once a year and top it up if necessary.

3. Clean The Skimmer Basket

Make sure to clean out the skimmer basket regularly to prevent debris from clogging up the filter.

4. Maintain Proper Water Chemistry

Maintaining proper water chemistry is essential for the longevity of your pool filter. Make sure to regularly test your pool water and adjust the pH, alkalinity, and chlorine levels as needed.

5. Schedule Regular Maintenance

It's a good idea to schedule regular maintenance with a pool professional to keep your filter in top condition. They can inspect your filter and make any necessary repairs or replacements.


In conclusion, a Hayward sand filter is an excellent choice for keeping your pool clean and safe. The amount of sand you need will depend on the size of your filter and pool. Installing sand in your filter is a simple process, and regular maintenance will ensure it continues to function effectively. By following these tips, you can keep your Hayward pool filter in top condition and enjoy your pool all summer long.
