How to Put New Sand in Pool Filter

If you own a swimming pool, maintaining its cleanliness is important to ensure the safety of your family and friends. One of the essential pieces of equipment that you need to maintain is the pool filter. Sand filters are commonly used in swimming pools to keep the water clean and clear. However, over time, the sand inside the filter may become clogged and need to be replaced with new sand. In this article, we will guide you on how to put new sand in a pool filter.

Understanding Sand Filters

Sand filters are a popular type of pool filter as they are efficient and cost-effective. They work by passing water through a layer of sand, which traps dirt and debris in the filter media. The clean water then returns to the pool. Sand filters typically require backwashing, which involves reversing the flow of water to clean the sand and remove any trapped debris.

When to Replace Sand

Over time, the sand in a pool filter can become clogged with dirt and debris, which can impact the filter's efficiency. In general, sand filters need to be replaced every five to seven years. However, if you notice that the water flow is reduced, or the water is not as clear as it used to be, it may be time to replace the sand.

Preparing for the Replacement

Before you start replacing the sand in your pool filter, ensure that you have the following tools and supplies:

- New pool filter sand

- Screwdriver

- Socket wrenches

- Shop vacuum

- Garden hose

- Teflon tape

- Safety glasses

Submerge the Sand

The first step in replacing the sand in your pool filter is to submerge the new sand in water. Place the new sand into a large container filled with water and let it sit for at least an hour. This will remove any dirt, dust, or debris from the sand.

Drain the Filter

Before you can remove the sand, you need to drain the pool filter. Start by turning off the power to the pump and closing the valves on the inlet and outlet pipes. Use a screwdriver to remove the drain plug at the bottom of the filter to drain any remaining water.

Remove the Old Sand

After draining the filter, use a socket wrench to remove the top of the filter. Carefully remove the old sand using a shop vacuum, making sure to avoid damaging the laterals or fingers at the bottom of the filter. After removing the old sand, use a garden hose to rinse out the filter to remove any remaining debris.

Replace Laterals or Fingers

Inspect the laterals or fingers at the bottom of the filter for any cracks or damage. If they are damaged, replace them before adding the new sand to prevent any leaks.

Add New Sand

Now that the old sand has been removed, it’s time to add the new sand. Using a funnel, slowly pour the new sand into the filter, taking care not to damage the laterals or fingers. Fill the filter with water until the level of the sand is above the laterals or fingers.

Reassemble and Test

Once the new sand has been added, it's time to reassemble the filter. Ensure that all the air is removed from the filter and that the O-ring is properly seated. Use Teflon tape on the threads of the filter to prevent any leaks. Turn the pump back on and check for any signs of leaks. After 24 hours, backwash the filter for two to three minutes to remove any fine particles from the new sand.

Conclusion

Replacing the sand in your pool filter is a simple process that can significantly improve the efficiency of your pool filter. By following the steps above, you can replace the sand in your pool filter quickly and easily. Remember to replace the sand in your pool filter every five to seven years to keep your pool clean and clear.
