How Do You Change Pool Filter Sand?

As a pool owner, the maintenance of the pool is crucial. One of the important aspects of pool maintenance is to make sure that the pool filter is working properly. The pool filter helps to keep the pool clean by trapping dirt, debris, and other particles in the pool water. Over time, the pool filter sand becomes dirty and clogged and needs to be changed. In this article, we will provide a step-by-step guide on how to change pool filter sand.

1. Determine the Type of Filter You Have

The first step in changing pool filter sand is to determine the type of filter you have. There are three common type of pool filters: sand filters, cartridge filters, and diatomaceous earth filters. Sand filters are the most common type of pool filter. In this article, we will be focusing on how to change pool filter sand in a sand filter.

2. Drain the Pool Filter

The next step is to drain the pool filter. To do this, turn off the pool pump and the valves that control the flow of water. Then, open the air relief valve on the top of the filter to release the pressure. After that, remove the drain plug and let the water drain out.

3. Remove the Sand

The next step is to remove the sand from the pool filter. To do this, use a gravel vacuum or a shop vac to remove as much of the sand as possible. If the sand is too hard to remove, you may need to use a garden hose to break up the sand.

4. Clean the Pool Filter Tank

Once the sand is removed, it is important to clean the pool filter tank. Use a hose to wash down the inside of the tank and remove any debris. Be sure to clean any spider webs or other debris that may have accumulated in the filter.

5. Replace the Filter Sand

The last step in changing pool filter sand is to replace the sand. To do this, pour the new filter sand into the pool filter tank slowly. Be sure to fill the tank up to the recommended level. Once the sand is in, you can replace the drain plug and the air relief valve.


Changing pool filter sand is an important part of pool maintenance. By following the step-by-step guide above, you can change the pool filter sand quickly and easily. Remember to always follow the manufacturer's instructions and use only recommended filter sand for your pool filter. With proper maintenance, your pool filter will continue to work properly and keep your pool clean for years to come.
