triton opel water coming out of shower overflow next to shower outlet, wate?

I think the pressure relief device has 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.
