If you are a pool owner, then you know the importance of keeping your pool clean and maintained at all times. One crucial aspect of pool maintenance is changing the sand in your pool filter regularly. This ensures that your pool water remains crystal clear by removing debris, particles, and contaminants from it. In this article, we will guide you through the process of changing sand out of a pool filter, step by step.

What is a pool filter made of?

Before we dive into how to change sand out of a pool filter, it's essential to understand what your pool filter is made of. It comprises of three essential parts: the filter tank, the standpipe, and the lateral assembly.

The filter tank is the large cylinder-shaped tank that houses the sand media. The standpipe is a central pipe that runs down the center of the filter tank and is connected to the laterals at the bottom of the tank. Finally, the lateral assembly is a group of thin, horizontal tubes that branch out from the standpipe and allow water to pass through the sand.

Why should you change your pool filter sand?

Over time, the sand in your pool filter can become clogged with debris, particles, and contaminants that the filter has trapped over time. This can cause a few problems:

• The filter will become less efficient at removing debris from your pool water.

• This debris can create a breeding ground for harmful bacteria.

• Overworking to reduce the efficiency of the filter can lead to higher energy costs.

When should you change your pool filter sand?

There isn't a straightforward answer to this because it depends on various factors such as the size of your pool, frequency of use, climate, and more. As a general rule of thumb, however, you should aim to change your pool filter sand every three to five years. You can also monitor the pressure gauge on your filter system, which will let you know if the filter is becoming less efficient.

How to change sand out of a pool filter.

Step One: Turn off the pool system

Before you start, it's crucial to turn off the pool system to avoid any accidents. You can do this by shutting off the electricity at the breaker or switch or by simply unplugging your pool filter pump.

Step Two: Remove the old sand

Now you need to remove the old sand from the filter tank. To do this, carefully remove the filter drain cap at the bottom of the tank and allow the sand to drain out. You might need to use a wet/dry vacuum to get rid of any remaining sand.

Step Three: Inspect your lateral assembly

We suggest taking this opportunity to inspect your lateral assembly for any damage, wear or tear. If you find damage, replace it before installing the new sand.

Step Four: Add the new sand

This is the most crucial step in the process. Once the old sand is removed and the assembly is inspected, you can add fresh sand. Make sure to choose the right type of sand as pool filter sand is not just any sand. You can find pool filter sand and sand alternatives at your local pool supply store.

Step Five: Reassemble the filter

After you have filled the tank with new sand, you can reassemble the filter. Ensure that the laterals are properly seated and that the standpipe is not clogged. Finally, replace the cap at the bottom of the tank.

Conclusion

Changing the sand out of a pool filter is not a complicated process. It just requires a bit of attention to detail and some patience. By following the steps outlined above, you'll be able to keep your pool crystal clear all year round while saving yourself some money on energy costs. Remember to change your pool filter sand every three to five years or as needed based on the pressure gauge reading.
