About the PondXpert ElectroAir 4mm Check Valve
Manufacturer: PondXpert
This non-return check valve helps to control the flow of air into your pond or aquarium.
This check valve protects your pump from damage caused by back-siphoning as a result of accidental power loss. It also prevents water from siphoning through the airline. It has low resistance which means it will not affect the air flow of your air pump and can be easily installed anywhere along the airline.
PondXpert ElectroAir 4mm Check Valve Features
Fits 4mm airline
Reviews for PondXpert ElectroAir 4mm Check Valve

Not sure they are needed but better to be safe than sorry for what amounts to a few pennies per line.

It works. Air goes one way and not tother.
4th July 2022
Bought to extend air line whilst also providing anti siphon protection. Seem to work well, low cost and easy to fit.
22nd April 2022
get these for end of pipe, saves water passing up the tube when aerator switched off which can then provide a barrier to air flow to the stones
