Bubble Column and Wall Pump Non Return Valve

The air from the pump of your Water Bubble Tube and/or Bubble Wall must only flow in one direction. This valve is to prevent the backflow of water from the Bubble Tube/Wall into your air pump system. This product should be replaced yearly as part of your maintenance and cleaning routine.

Includes 2 valves- replace after 12 months of use.

Please attach the black end of the valve facing towards the pump and the clear end facing towards the bubble tube/wall.
