Just sprang a leak with my hotwater system (gas type).

Its a bit odd, seems to be a decent trickle down the side from the very top of the unit next to the exhaust vents, gathering on the top of the unit outside and streaming down the side of the exterior.

First tried operating the pressure relief value which gets very hot the longer its operated, but the trickle from the leak is same strength of barely warm water..

So I assume theres some fresh water fitting entering near the top of the tank thats leaking? I do have a solar unit on the roof but dont think that really maters.. no leak coming from the roof piping, joining to the unit.

Any suggestions or system is toasted and get a new one.
