How do you fix the problem if even after replacing sand in your pool filter skimmer basket still blows out with water about 8 ft high when turn pump off?

Reason: When it comes to high pressure from the pool filter, the only plausible conclusion is that there is a blockage somewhere in the filter system, thereby inhibiting water flow. To address this issue, consider the following possible solutions.

Possible Solutions:

1. Clogged Impeller: Start by turning off the pool pump and checking if the impeller is blocked by debris. Remove any obstructions or buildup that might be hindering the smooth operation of the impeller. Make sure the pump lid is secure to prevent air from being sucked and causing problems with the pump

2. Blocked Filter Element: If the impeller is clear, inspect the filter element for dirt or debris. Remove anything trapped in the element and clean or replace it if needed. Ensure the element is properly seated to avoid water leaks.

3. Leaking O-rings: Examine the O-rings in your filter system. If they appear damaged or worn, replace them. This can prevent water from bypassing the filter and causing the pressure buildup.

4. Damaged Filter Media: If the filter uses sand, check the media to ensure it is clean and free from impurities. Backwash the filter according to the manufacturer's guidelines to remove any compacted dirt and achieve optimal filtration. Replace the media if it's too dirty or outdated.

5. Check for Blockage: Trace the entire pool plumbing system for blockage or narrow points that may restrict water flow. This can include checking the pipes connected to the filter , the return jets, and the vacuum line.

6. Faulty Pressure Relief Valve: Your filter may have a pressure relief valve that helps regulate high water pressure. If this valve is malfunctioning or unable to open, it can result in excessive pressure. Have it inspected and repaired if necessary.

7. Pump Overpowering the system: If the pool pump is to large for the size of the pool or the filter, it might generate excessive pressure. Consult a pool professional to ensure you have the right pump for your pool setup.

8. Check the Plumbing System: Look for leaks in the plumbing pipes or connections. Address any cracked, damaged, or leaking pipes that could cause water pressure abnormalities.

9. Air Leak: Ensure that there are no substantial air leaks in the system. Air pockets can cause pressure to fluctuate. Inspect all connections and seals to rectify any leaks.

10. Consult a Professional: If none of the above suggestions resolve the issue, it might be time to seek the help of a qualified pool technician or company. They can conduct a comprehensive diagnosis and repair the underlying problem.
