Hi there,
I've got a little problem with my boiler. What happened when the hot water suddenly disappeared (whilst being left in charge of my host family's house ). I was told to open some tap to get the pressure back up to 1.5bar. Only not knowing what I was doing, left it too long (until 2bar). I therefore opened another tap to let out the excess water coming out from a rubber pipe. I was able to get back hot water only now there is a constant dribble from the same pipe making the pressure decrease and cutting the hot water. ???? Pleaseee help me!
Thank you very much

From what you say, you have opened the over pressure valve, Which really you should never do.
Replace the valve.
You could try, opening and closing the valve a few times, might stop the leaking, if not, replace the valve. You should of kept a check on it.
