Before you start replacing the sand in your pool filter, you will need to gather some necessary items that will make the process more comfortable. Here's a list of the things you will need.

• Sand - you will need enough sand to fill your filter.

Step By Step Guide: How To Put Sand In A Pool Filter

Now that you have everything you need to replace the sand in your pool filter let's discuss how to put sand in a pool filter.

Step 1: Prepare the filter for sand change

Start by turning off the pump that is connected to the pool's filter. Then drain the water out of the system by opening the bottom drain plug. If you have a multiple-pipe system, you can use a hose to drain it out. You can also use a wet/dry vacuum to remove the water.

Step 2: Remove the top of the pool filter

Using a Phillips screwdriver, remove the screws that hold the top of the pool filter into place. Once removed, lift the top off and remove the old sand.

Step 3: Clean the filter

The next step is to clean out the inside of the filter. You can use a hose with a spray nozzle attachment, or a wet/dry vacuum to remove the dirt and debris. Be sure to clean the filter thoroughly to ensure that all impurities are removed.

Step 4: Replace the lateral assembly

Before putting new sand into the pool filter, carefully check the lateral assembly and replace all damaged parts if necessary. The lateral assembly is a set of tubes that directs the filtrate (water) through the sand bed.

Step 5: Add the new sand

Now it's time to add the new sand. Start by pouring about a third of the sand into the filter then add water to the filter. This will help to prevent too much sand from being stirred up.

Step 6: Repeat step 5

Now keep pouring the sand into the filter and adding water until the filter is filled.

Step 7: Close the filter and turn on the pump

Once the filter is filled with sand, it's time to put the top of the filter back on. Make sure the gasket o-ring is in place before closing the filter. Secure the top of the filter with the screws, then turn on the pump. The filter should start working immediately.


If you own a pool, then maintaining it is crucial to keeping the pool water clean and safe for swimming. One important part of maintaining the pool is to replace the sand in the filter. It may seem like a daunting task, but by following the above step-by-step guide, you can change the sand in your pool filter and keep your pool water looking and feeling great!
