If you have a pool, it's important to keep the water clean and safe for swimming. One of the essential components of maintaining a pool is the use of a pool filter. A sand filter is a common type of pool filter that is often used to remove dirt and debris from the pool water. But over time, this filter can become clogged and dirty, leading to poor filtration and potential issues with your pool. In this article, we will show you how to clean out a sand pool filter.

Understanding Sand Pool Filters:

Sand pool filters work by using special sand to trap dirt and debris from the pool water. The filter will typically have a layer of sand that is several inches thick, which acts as an effective filtration medium. When the water passes through the sand, the dirt and debris are trapped, and the clean water flows back into the pool.

Over time, the filter will become clogged with dirt and debris, making it less effective at filtering out contaminants from your pool water. This is why it's essential to clean out your sand pool filter regularly.

Materials You Will Need:

Before you start cleaning out your sand pool filter, make sure you have the following materials handy:

• A garden hose

• A bucket

• A replacement sand filter

• A sand filter cleaner

• A Phillips head screwdriver

Steps to Clean Out Your Sand Pool Filter:

Step 1: Turn off the pump

Before you start, make sure you turn off the pool pump to prevent damage to the filter system.

Step 2: Remove the sand filter

Next, locate the sand filter and remove the top valve cover. This will expose the sand filter and allow you to access the sand inside.

Step 3: Remove the sand

Use a scoop or a bucket to remove the sand from the filter. You can also use a wet/dry vacuum to suck the sand out.

Step 4: Inspect the sand filter

Once you’ve removed the sand, inspect the sand filter for any cracks, chips or other damage. If you find any damage, you'll need to replace the filter.

Step 5: Clean the sand filter

Using a sand filter cleaner, follow the manufacturer's instructions to clean the filter. This will help remove any remaining debris from the sand filter.

Step 6: Rinse the sand

Rinse the sand thoroughly with clean water to remove any remaining dirt and debris.

Step 7: Refill the sand filter

With the sand filter completely cleaned out, pour new sand into the filter, filling it about two-thirds of the way full.

Step 8: Reassemble the sand filter

Reassemble the sand filter, making sure you tighten all the parts and replace any damaged components.

Step 9: Restart the pool pump

Once you’ve reassembled the sand filter, turn the pool pump back on and make sure it's running correctly.

Tips for Maintaining Your Sand Pool Filter:

1. Clean out your sand pool filter regularly. How often you need to clean your filter will depend on how often you use your pool, but a good rule of thumb is to clean your filter at least once a month.

2. Check the sand filter's pressure gauge regularly to ensure it’s working correctly. If your pressure gauge is reading high, it's a sign that your sand filter may be clogged and needs cleaning.

3. Replace the sand in your filter every five years. Over time, the sand in your filter will break down, leading to less effective filtration. Replacing the sand will help keep your filter working efficiently.

4. Keep your pool clean. Preventing dirt and debris from entering your pool in the first place is the best way to keep your sand filter clean and clog-free.

5. Hire a professional. If you’re not comfortable cleaning out your sand pool filter yourself, it's always a good idea to hire a professional pool service to do the job for you.


A sand pool filter is an excellent way to keep your pool water clean and safe, but it's essential to keep it maintained and clean to ensure its effectiveness. Follow these simple steps to clean out your sand pool filter, and you can enjoy crystal clear pool water all summer long. Remember to maintain your filter regularly, replace the sand every five years, and check the pressure gauge to ensure your filter is working correctly.
