this morning went to have a bath and the hot water was just a trickle. checked all other taps, they were the same. taps not blocked, heating works , and can only get hot water when the heating is on. pressure looked a little low on boiler so, went to fill as i have done in the past, nothing happening. mains ok as i tested with cold running taps. it just seems that where the pipe goes into the boiler it is blocked, help please as the pressure drops when i use the central heating, so i guess i have a couple of days until im in trouble.
