Hi - the Overflow from the Expansion tank has recently started spewing hot water into the garden, at periodic intervals.
On investigating, the vent pipe from the hot-water cylinder is the culprit, with spurts of water topping the expansion tank up.
Any suggestions? Those that spring to my mind are:
(a) thermostat has gone
(b) hot water tank contains too much water initially
(both cases on the assumption there is too much water, so the excess is being fired out through the vent pipe)
Appreciate any advice on most likely cause, and possible solution
Tks
