This blog post will provide a comprehensive guide on how to backwash sand filter Hayward, ensuring your pool water stays crystal clear and healthy.
Understanding Backwashing
Backwashing is a critical process that reverses the flow of water through the sand filter. This process helps to remove dirt, debris, and accumulated impurities that can clog the filter media over time. By backwashing, you restore the filter’s efficiency and prevent premature wear and tear.
Step-by-Step Backwashing Instructions
1. Preparation
- Turn off the pool pump.
- Set the filter valve to the “Backwash” position.
- Open the air relief valve located on top of the filter to release any trapped air.
2. Backwashing
- Turn on the pool pump.
- Allow the water to flow through the filter in the reverse direction for approximately 2-3 minutes, or until the sight glass shows clear water.
3. Rinsing
- Turn off the pool pump.
- Set the filter valve to the “Rinse” position.
- Turn on the pool pump and run it for about 30 seconds to remove any remaining debris.
4. Resetting
