Keep your water circuit primed with a non-return valve for 10mm or 12mm hose

Are you fed up with your water pump losing its prime or water backing up in your sink? This is a common problem in van water installations, and it can put your pump under severe strain. This non-return valve is the simple solution to make your circuit reliable. 

Thanks to its back-pressure mechanism, it instantly blocks any liquid backflow, ensuring unidirectional water flow. It protects your pump (submersible or pressure group) from losing prime and prevents unwanted backflow.

Easy to install, it is essential after the pump or before the water heater. For optimal installation, use it with our extra flexible 10mm drinking water hose.
