Manual Backwashing Vessels


Our Manual Backwashing Vessels are a cost effective alternative to automated backwashing systems, allowing for installation in remote locations where they may not be access to a power supply. The backwash process is controlled manually by simply turning the handle from the service to backwash position. The Runxin F56A valve included has 1” BSP inlet, outlet and drain connections and can be configured as down-flow or up-flow. These systems are supplied empty and can be filled with your choice of media, such as granular activated carbon, filtration sand or pH correction media.

Manual backwashing valves allow you to change the direction of flow through the media, backwashing it to remove sediment, bacteria and debris. Supplied as a partially assembled kit with Runxin F56A manual backwashing valve, base seal ring, three 1” washers, riser tube, distribution system and an empty water treatment vessel. The empty vessel can then be filled with your choice of media depending on the application. Vessels are available from 38.9L to 250L capacity.

How Often Do I Need To Perform A Backwash?
This depends on the media you choose to fill the vessel with. As an example for carbon, filtration sand and pH correction media we would recommend performing a backwash once every 3-7 days depending on the quality of the feed water.
