How to Clean an Inground Pool Sand Filter Tank

Cleaning an inground pool sand filter tank is an essential task that pool owners need to perform regularly. The sand filter tank is responsible for removing dirt and debris from the pool water, so it's crucial to keep it clean to ensure that your pool stays clear and safe to swim in. Here's a step-by-step guide on how to clean an inground pool sand filter tank.

Step 1: Turn off the pool pump and close the valves

Before cleaning the sand filter tank, turn off the pool pump and close the valves that lead to and from the filter. This will prevent water from flowing into the tank while you're cleaning it.

Step 2: Release the pressure

Next, release the pressure from the sand filter tank. To do this, locate the pressure release valve on the top of the tank and turn it counterclockwise. This will release any built-up pressure in the tank.

Step 3: Remove the sand filter tank cover

Once the pressure has been released, remove the sand filter tank cover. This can usually be done by unscrewing the bolts that hold the cover in place.

Step 4: Remove the sand

Using a sand filter scoop, remove the sand from the tank. Be sure to dispose of the sand properly, as it may contain dirt and debris that could contaminate your yard or garden.

Step 5: Clean the tank

With the sand removed, use a hose to clean the inside of the tank. Pay special attention to the laterals, which are the small tubes that run from the center of the tank to the edges. These can become clogged with debris, so be sure to clean them thoroughly.

Step 6: Inspect the laterals

While you're cleaning the laterals, inspect them for any signs of damage or wear. If you notice any cracks or other damage, they will need to be replaced before you can put the sand back in the tank.

Step 7: Replace the sand

Once the tank is clean and the laterals are inspected, it's time to replace the sand. Be sure to use the correct type of sand for your filter, as using the wrong type can damage the filter and reduce its effectiveness.

Step 8: Reassemble the tank

With the sand in place, it's time to reassemble the sand filter tank. Replace the cover and tighten the bolts to secure it in place.

Step 9: Open the valves and turn on the pump

Finally, open the valves that lead to and from the filter and turn on the pool pump. Check for any leaks or other issues, and make sure that the filter is working properly.

Cleaning an inground pool sand filter tank can be a bit of a chore, but it's an essential task for any pool owner. By following these steps, you can ensure that your filter is working properly and that your pool stays clean and safe to swim in.
