How to Change Sand in a Swimming Pool Filter

Swimming pool filters need to be maintained regularly in order to keep the pool clean and functional. One of the most important aspects of maintaining a swimming pool filter is changing the sand inside of it. Over time, debris and contaminants can build up in the sand, making it less effective at cleaning the water. In this article, we will take a closer look at how to change the sand in a swimming pool filter, step-by-step.

Understanding Your Swimming Pool Filter

Before we get into the actual process of changing the sand in your swimming pool filter, it’s important to understand a few key things about the filter itself. The filter is responsible for removing debris and contaminants from your pool water in order to keep it clean and clear. There are three main types of swimming pool filters: sand, cartridge, and diatomaceous earth (DE). Sand filters are the most common type of filter, and are typically the easiest to maintain.

Choosing the Right Sand

When it comes to changing the sand in your swimming pool filter, the first step is to choose the right type of sand. The most commonly used type of sand for swimming pool filters is called #20 silica sand. This type of sand is specifically designed for pool filters, and is available at most pool supply stores.

Preparing the Filter

Before you can change the sand in your swimming pool filter, you’ll need to prepare the filter itself. Start by turning off the pump and releasing the pressure from the system. Next, remove the drain plug at the bottom of the filter to drain out any remaining water. Once the filter is completely drained, you can remove the top of the filter and access the sand inside.

Removing the Old Sand

To remove the old sand, you will need to use a sand removal tool. This is a specialized tool that is designed to scoop out the old sand without damaging the filter itself. Slowly start removing the sand from the filter, being careful not to damage any of the internal components.

Cleaning the Filter

Once all of the old sand has been removed, it’s time to clean the inside of the filter. Start by using a garden hose to rinse out any remaining sand particles. Next, use a filter cleaner to remove any built-up debris or contaminants that may be stuck to the inside of the filter. Rinse the filter off again with the garden hose to remove any remaining debris or cleaning solution.

Adding the New Sand

With the filter cleaned and prepped, it’s time to add the new sand. Start by pouring in a layer of sand that is about 1/3 of the way up the filter. Use a scoop to spread the sand evenly across the bottom of the filter. Continue adding sand in layers until the filter is full. Be careful not to overfill the filter, as this can cause damage to the internal components.

Closing Up the Filter

Once the new sand has been added, it’s time to close up the filter. Replace the top of the filter and make sure it is securely fastened. Reattach the drain plug and turn the pump back on. It’s important to check the filter for any leaks or cracks before starting the pump to ensure that everything is working properly.

Conclusion

Changing the sand in a swimming pool filter is an important part of maintaining your pool’s cleanliness and functionality. With the proper tools and a little bit of know-how, it’s a relatively simple process that can be done in a few hours. Following the steps outlined above will ensure that your filter is working properly and that your pool stays clean and clear.
