the general temperature of my britony water heater seems to be deteriorating over a period of time in as much as it is difficult to run a hot bath with a resonable temperature of water. can you offer any help re this problem. thanks.
Similar problem. Change Diaphragm (£15) or thereabouts. Will probably find a small hole or deterioration of the rubber in the old one.

If you have thermostatic mixer taps on baths the problem can be there.
