Automatic contactor with non-return valve

0.4 Bar or 1 Bar pressure switch for 10/12 mm diameter hose

A 0.4 or 1 Bar automatic switch (to be chosen according to the pressure of your water pump) with non-return valve is an essential piece of equipment for optimising the water distribution system for your sink in your converted vehicle. It acts as a switch to activate or stop the water pump mechanism.

Installing an automatic contactor with non-return valve

Your pressure switch will be connected by a crystal water hose between your water tap and your water pump. You will need to make the necessary electrical connections for it to work. Once installed, when you open the tap, the pressure will drop, so the pump will start, and conversely, when you close it, the pressure will increase, so the pump will switch off automatically.

The built-in non-return valve will prevent any backflow to protect your distribution system (water pump).
