Metlex Aquatron water heater - overflow problem

I have an Aquatron over-sink water heater (effectively a shower unit). When the water control knob is turned on, water pours out of the overflow pipe and reduces the flow from the tap. Any ideas why this might be happening. Can it be rectified? Any help welcomed.

I think the Pressure Relief Device (PRD) may have blown. 

It’s a safety device on the bottom of the heating tank.

It is fairly easy to replace however there is usually something that causes it to blow, often a kink in the hose or the showerhead is blocked, so check this before fitting the new PRD.

Unfortunately I don’t know which model you have so I can’t advise on your particular PRD
