Manual Backwash Heads

Manual backwash heads are a simple, cost-effective solution for operating media filtration vessels where automated control is not required. Designed for use with sand, AFM®, Birm, Katalox Light, GAC, and other filtration media, these heads allow users to manually initiate and control backwash cycles—removing trapped sediment and contaminants to restore filter efficiency and extend media life.

Ideal for borehole systems, rainwater harvesting, pre-filtration, and light commercial or residential water treatment, manual backwash valves are typically mounted onto FRP vessels (e.g. 8x35, 10x54, 13x54, etc.) and feature easy-turn levers or rotary dials to switch between service, backwash, and rinse modes. Available in various thread sizes and port orientations to suit different system designs.
