Step by Step Guide
When the filter pressure rise 8-10 PSI over the clean starting pressure, it is time to backwash.
- Turn the pump off and rotate the multiport valve to backwash.
- Turn on the pump and the dirty water will flow out of the waste line.
- Once the water runs clear in the valve’s sight glass, turn off the pump.
- Rotate the valve to rinse.
- Turn on the pump for 20-30 seconds. This will clean out the plumbing lines and reset the sand bed.
- Turn off the pump, rotate the valve to filter position and begin to filter.
- Take a reading of this new clean starting pressure, so you have a reference point for the next backwash cycle.
- Water may need to be added to the pool to replace the backwashed water.
IMPORTANT: Make sure you turn the pump off each time you turn the multiport valve. That valve cannot be turned with pump running.
