Multi-port valve is the best option for connecting to the sand file tank. It is a type of valve that normally has more than two ports.
The multiport valve has 6 settings:
- Filter – Water enters through the top of the filter, flows through the filter media, and exits at the bottom, returning to the pool.
- Waste – Water enters the multiport valve and exits through the backwash pipe, bypassing the filter media.
Filter - Closed – This setting blocks off all entrances to the filter. No water can enter or exit the filter. This setting is used when changing the filter media.
-
Backwash - Backwash – Water enters the bottom of the filter through the filter fingers, disrupting the filter media to remove the dirt and debris, and exits through the backwash pipe.
- Bypass/circulate – Water enters and exits the multiport valve, flowing back into the pool without going through the filter media.
- Rinse – Water enters at the top of the filter, flows through the sand, exits through the filter fingers at the bottom, and out through the waste pipe.
