Hi,
I have a Main Mersey Super gas fired water heater and don't seem to be getting any hot water.
The pilot light is remaining lit and is not firing up, I have also noticed the pressure seems to be a wee bit higher since developing this fault.
I've checked the instruction booklet in the fault finding section and there is a couple of things that it could be. Advice from more experienced forum users would be helpful.

Thanks

if you have had to relight the pilot recently, check that it is set to main flame and not just to pilot! :wink:
if it's the model i'm thinking off it could be the water governor unit, possibly the diaphram inside it or a blockage in the venturi
