The 5 litre EXP5 Surejust tank suitable for use as a domestic water expansion tank.

Expansion tanks (used on the hot water side) need to be set above the maximum pressure of the pump but below the pressure of the pressure relief valve (PRV).

This 5 litre Supa Surejust expansion tank is supplied with mounting brackets and connections for 15mm ID flexible plumbing. It is also possible to remove the 15mm hose tail to reveal a 1/2" BSP male thread.
