Step-By-Step Guide to Changing Your Pool Filter Sand

Now that we've outlined the importance of changing your pool filter sand let's go over the steps that you can take to make it happen.

1. Turn Off the Pool Pump

Before you start changing your pool filter sand, you want to make sure that your pool pump is turned off. You do not want to work on a running pump.

2. Locate the Pool Filter

Your pool filter is likely located somewhere near the pool, often attached to the pool motor. It's a large cylinder with a removable lid on top. Be sure that you know how to access your pool filter before you begin changing the sand.

3. Remove the Old Sand

To remove the old sand, you'll need to take off the pool filter lid. Then, use a pair of pliers to remove the lateral tubes located in the pool filter. If your pool filter is old, these tubes may be brittle, so be careful not to snap them.

Next, take out the old pool filter sand using a hack saw, making sure not to damage the lateral tubes. You will want to remove as much sand as possible and dispose of it properly.

4. Clean Out the Pool Filter

After removing the sand, use a garden hose to thoroughly rinse out the pool filter's inside. This will remove any remaining dirt and debris that may be lingering.

5. Replace the Lateral Tubes

Next, reinstall the lateral tubes back into your pool filter. Make sure they are correctly aligned and that you don't damage the lateral edges during the process.

6. Adding the New Pool Filter Sand

Once the lateral tubes are back in place, it's time to add new pool filter sand. Begin by pouring the sand into the pool filter, making sure to distribute it evenly around the lateral tubes. Fill the pool filter to about two-thirds of its capacity.

7. Replace the Pool Filter Lid

Now that your pool filter is filled with sand, it's time to replace the pool filter lid. Tighten the lid to secure it in place.

8. Backwash Your Pool Filter

Finally, it's time to start your pool pump and backwash your pool filter. Backwashing means flushing the pool filter sand with water to remove any remaining dirt and debris. Backwash for two to three minutes, or until the water runs clear. Then, turn off your pump and let it settle for a few minutes.

In conclusion, replacing your pool filter sand is an essential part of maintaining your swimming pool. By following these steps, you will ensure that your pool filter stays effective at keeping your pool clean and safe for swimming. Remember, safety always comes first, so make sure that you turn off the pool pump before performing any maintenance tasks, including changing your pool filter sand.
