How it Works
How it Works
The Runxin F56A1 Manual Valve allows operators to manually initiate backwash and rinse cycles.
By rotating the handle, water reverses through the media bed, flushing out trapped dirt and sediment. This restores flow rate, prevents channeling, and prolongs filter media life.
