Maintaining a crystal-clear pool involves more than just regular cleaning; it requires periodic maintenance of essential components like the sand in your pool filter. Changing the sand in your pool filter is a crucial task that ensures optimal filtration and water quality. In this step-by-step guide, we’ll walk you through the process of changing the sand in your swimming pool filter, helping you keep your pool water sparkling and inviting.

How to Change Sand in Swimming Pool Filter?

Follow this step-by-step process:

Step 1. Get the Right Equipment:
Before diving into the process, gather the necessary equipment. You’ll need a screwdriver, a pipe wrench, a shop vacuum, new pool filter sand, and a replacement O-ring for the multiport valve.

Step 2. Turn the Power Off:
Prioritize safety by turning off the power to your pool pump. This ensures that there is no water flow during the sand-changing process.

Step 3. Drain the Tank:
Release the pressure from the pool filter by opening the air relief valve on the top. Once the pressure is released, use a shop vacuum to remove any excess sand or water from the tank.

Step 4. Remove the Multiport Valve:
Using a screwdriver, remove the screws securing the multiport valve to the filter. Carefully lift the valve off, taking care not to damage the plumbing connections.

Step 5. Remove the Old Sand:
With the multiport valve removed, access the old sand by reaching into the tank or using a scoop. Scoop out the old sand and dispose of it properly.

Step 6. Withdraw the Lateral Assembly and Pipe:
Underneath the sand is the lateral assembly and pipe. Lift them out, taking note of their arrangement. Inspect the laterals for any damage or wear.

Step 7. Wash the Tank:
Thoroughly clean the inside of the tank using a hose to remove any remaining sand or debris. Ensure the tank is free from contaminants before proceeding.

Step 8. Replace the Lateral Assembly and Pipe:
Carefully re-insert the lateral assembly and pipe into the tank, ensuring they are properly seated. Make sure the laterals are evenly spaced and in good condition.

Step 9. Add Fresh Sand:
Pour the appropriate amount of new pool filter sand into the tank. Consult your filter’s manual for the recommended amount. Distribute the sand evenly to promote efficient filtration.

Step 10. Inspect (and Possibly Replace) the O-ring:
Inspect the O-ring on the multiport valve for any signs of damage or wear. If needed, replace the o-ring with a new one to ensure a proper seal.

Step 11. Re-Set the Multiport Control Valve:
Place the multiport valve back onto the filter tank, securing it with the screws. Ensure all plumbing connections are tight and secure.
