Truma 10mm non-return valve: the solution for a reliable water circuit in your van

Nothing is more annoying in a van than constantly hearing the water pump reactivate, or noticing water flowing backwards to the tank, depressurising the circuit. This unwanted backflow can prematurely wear out your pump, whether submersible or pressure switch type, and disrupt your comfort by creating air pockets.

The Truma 10mm non-return valve (white version) is the essential technical component for securing your fresh water installation. Designed specifically for converted vehicle water circuits, this one-way connector instantly blocks any liquid backflow. Once installed, it ensures water flows only in the right direction, from the tank to your water points (tap, shower), but never in reverse.

Manufactured by Truma, a leading reference in van equipment, this non-return valve ensures perfect sealing and high reliability. It is designed to withstand the pressure of standard pumps (up to 6 bar) and supports hot water up to 80°C, providing lasting peace of mind, even if you have a water heater.

Installation is very straightforward. Thanks to its two barbed fittings (hose tail type), it fits directly onto your existing pipework. For optimal installation and perfect sealing, we recommend combining it with 10/14mm diameter crystal water hose and suitable hose clamps. It's the simple and economical solution to preserve your pump's lifespan and ensure a constant water flow as soon as you turn on the tap.
