What is a DE Pool Filter?
A DE pool filter is a type of filter commonly used in swimming pools to keep the water clean and free of impurities. It uses diatomaceous earth, a natural substance, to filter out even the smallest particles from the water, providing superior filtration compared to other types of filters.
When to Backflush a DE Pool Filter?
It is recommended to backflush a DE pool filter when the filter’s pressure gauge rises 8-10 psi above the normal operating pressure. This increase in pressure indicates that the filter is clogged with debris and needs to be cleaned to maintain efficient filtration.
Step-by-Step Guide to Backflushing a DE Pool Filter
- Turn off the pool pump: Before starting the backflushing process, make sure to turn off the pool pump to prevent any damage to the system.
- Locate the backwash valve: Find the backwash valve on your DE pool filter system. This valve is used to redirect the flow of water during the backflushing process.
- Connect the backwash hose: Attach the backwash hose to the waste port on the backwash valve. Make sure the hose is securely attached to prevent any leaks.
- Set the valve to backwash mode: Turn the backwash valve to the “backwash” position to redirect the water flow for cleaning the filter.
- Turn on the pump: Start the pool pump to initiate the backflushing process. The dirty water will be discharged through the backwash hose.
- Monitor the process: Keep an eye on the water flowing through the backwash hose. Once the water runs clear, the backflushing process is complete.
- Turn off the pump: Once the water is clear, turn off the pool pump to stop the backflushing process.
- Rinse the filter: After backflushing, it is recommended to rinse the DE filter with clean water to remove any remaining debris and diatomaceous earth particles.
- Set the valve to filter mode: Finally, turn the backwash valve back to the “filter” position to resume normal filtration operation.
Tips for Effective Backflushing
- Regular backflushing helps maintain the efficiency of your DE pool filter and prolong its lifespan.
- Monitor the pressure gauge regularly to determine when backflushing is required.
- Backflushing should be done at least once a month, or more frequently based on pool usage and environmental factors.
- Always follow the manufacturer’s instructions when backflushing your DE pool filter.
- Consider adding a filter cleaner or degreaser to enhance the backflushing process and remove stubborn debris.
Conclusion
Backflushing your DE pool filter is a simple yet essential maintenance task that helps ensure your pool water remains clean and crystal clear. By following the step-by-step guide outlined in this article and implementing the tips for effective backflushing, you can keep your DE pool filter in optimal condition and enjoy a sparkling pool all season long.
