Tools and Materials:
– New filter sand
– Shovel or bucket, Industrial vacuum cleaner (recommended for safeguarding internal filter components)
– Garden hose
– Duct tape or plug (optional)
– Allen wrench (if required for your specific filter)

Steps:
1. Switch off the pool and filter pump: Ensure the power to the pool is disconnected to prevent accidents.
2. Relieve pressure: Open the relief valve on top of the filter to reduce pressure within the system. Expect some water to escape, so be prepared.
3. Remove the filter valve or housing: Depending on your filter type, remove the valve on top or open the housing to access the filter sand.
4. Extract the old filter sand: Use an industrial vacuum cleaner, which we highly recommend, to safely and cleanly remove the old filter sand, ensuring the internal filter components remain undamaged.
5. Rinse the filter: Thoroughly rinse the inside of the filter with a garden hose to eliminate any remaining sand residue and other debris. Be cautious while rinsing to avoid damaging the internal filter mechanism.
6. Add new filter sand: Pour the new filter sand into the filter. Refer to your filter’s manual for the correct amount of sand suitable for your specific filter.
7. Seal the filter: Replace the filter valve or seal the filter housing securely according to the manufacturer’s instructions.
8. Backwash or Rinse the filter: Set the six-way valve to “Backwash” or “Rinse” before restarting the filter pump. This step is crucial to direct all dust and debris from the new sand to the sewer and prevent it from entering the pool.
9. Build pressure and test: Close the relief valve and restart the filter pump. Let the pump run to establish normal pressure within the system.
10. Check for leaks: Thoroughly inspect for any leaks around the filter housing and ensure everything is properly sealed.
11. Restart the pool: Switch the pool back on and verify that everything is functioning correctly. Regularly monitor water quality to ensure the new filter sand is working effectively.

Replacing filter sand is a crucial aspect of pool maintenance. Ensure strict adherence to your specific filter manufacturer’s instructions for optimal results.
