Sand filters are commonly used to maintain swimming pool cleanliness. It filters dirt, debris, and impurities that make your pool water cloudy and uninviting. However, the sand filter itself can sometimes become clogged with sand, causing it to lose filtering efficiency. In these instances, it is important to know how to get the sand out of a pool filter.

Over time, sand filters may become clogged and dirty. When you notice a rise in pressure or decreased water flow, it's likely your sand filter needs cleaning. Another way to tell it's time for cleaning is when you notice that the water in your pool is becoming cloudy again, despite running the filter.

2. Turn off the pump

Before you commence cleaning, you'll need to switch off the pool pump. This will prevent water from flowing in your pool and pouring into your filtration system, ensuring your safety while working around the filter.

3. Drain the pool filter

Once you have turned off the pool pump, turn off the valves that control water flow to and from the filter. The goal is to drain as much water from the filter as possible. With the pump off, turn the hand valve to the backwash setting. This will flush water out of the filter and loosen the sand from the interior chamber.

4. Remove the filter's top and inspect

Remove the top portion of the sand filter and carefully place it aside. Use this opportunity to inspect the filter's interior tank for signs of wear and tear, such as broken or chipped parts. Your pool supply store should have replacement parts that you can purchase to repair your system.

5. Remove and inspect the sand

Before you can get the sand out of a pool filter, you'll need to remove it. First, use a trowel or scoop to extract as much sand as possible. Examine each handful of sand, separating the damaged sand from the usable. Replace any broken pieces you find.

6. Clean the filter system

With the sand emptied from the filter, take the opportunity to clean out the filter system. Use a brush to remove dust and debris from the interior of the tank, including the laterals and the underdrain, which the water passes through once it's been filtered.

7. Add new sand

Once the system is clean, add new sand to your filter tank. Check your manufacturer's recommendation to ensure the appropriate amount of sand is used. Distribute the sand evenly to avoid obstructions, and to ensure that water flows easily through the system.

8. Reassemble the filter

After you've put new sand into the filter tank, it's time to reassemble the filter. Replace the top portion of the tank and install the filter's valve. The valve controls the water flow through your filtration system so that it can function correctly. Once you've reassembled your system, turn your pump back on to ensure that everything is working correctly.
