A 40 litre underslung water storage tank in black, designed for campervan conversions. It is made from WRAS (Water Regulations Advisory Scheme) approved polyethylene, so the material is suitable and safe for storing potable (drinking) water.
The tank mounts underneath the vehicle, which saves space inside the campervan and keeps the centre of gravity low. Eight moulded brass M8 threaded inserts let you mount it securely, and two moulded brass vents allow ventilation and pressure regulation within the tank. There is a moulded inlet for filling and a choice of three outlets, one of which includes a sump.
Designed for campervan conversions and to fit a wide range of vehicles. Check the space under your vehicle before ordering: the tank measures 170mm high, 370mm wide and 750mm deep.
