Swell Non Return Valves allow air to pass through, but prevent water returning down the air line and into the electrics of the pump.

It's essential to maintain safety and performance in all manner of aquatic devices, such as air pumps, so you'll find that this device is really useful. The valve is fitted onto the airline between the pump and air stone or pump.
