The boiler has been working fine for the last 5 years. I replaced all the radiators 3 years ago and put 2 towel rails in the bathroom this summer. Inhibitors also replaced this summer. The boiler has started to make a Knocking/Clicking noise for a couple of seconds when any of the hot water taps are turned on (when the CH is also on). The hot water heats up fine. I did notice some drips of water from the front cover a couple of weeks ago, but this has now stopped, so I have not removed the front panel. ANY IDEAS/POINTERS? is it the flow priority valve?
