How to Lower Water Level in Pool with Sand Filter?

To lower the water level in your pool using a sand filter, you will need to bypass the filter and pump the water out through the waste line. Here's a detailed guide on how to do it:

Step-by-Step Guide to Lowering Pool Water Level

1. Turn Off the Pump: Ensure the pool pump is completely turned off before proceeding. This is crucial for safety and proper valve operation.

2. Adjust the Three-Way Valve: Locate the black three-way valve, usually positioned in front of the pump. With the pump off, close the skimmer line using this valve. This directs the suction solely from the main drains at the bottom of the pool.

3. Set Filter Valve to Waste: Change the filter's multi-port valve or dial to the "waste" position. This setting allows water to bypass the sand filter and be directly expelled through the waste line.

4. Turn the Pump Back On: With the multi-port valve in the "waste" position, turn the pump back on.

5. Monitor Water Level: Keep a close eye on the pool's water level as it lowers. Be careful not to lower it too much, as this could cause problems with your pump and skimmer operation.

6. Turn off Pump When Done: Once you are finished lowering the water level, turn off the pump.

Important Considerations

• Know Your Waste Line: Ensure that your waste line is directed to an appropriate area for water disposal, such as a drain or other designated location.
• Avoid Over-Draining: Lowering the water level too much can damage your pool equipment. Be cautious and do not drain below the skimmer opening.
• Pump Operation: Never operate your pump with the filter dial in the “waste” position unless you are actively lowering the pool water level. This can damage your pump if left running in this position.

By following these steps, you can effectively and safely lower the water level in your pool using your sand filter system.
