[QUOTE="binky, post: 505754, member: 490"] I had a problem with dirt on the PRV valve many years ago. The expansion vessel had failed, so we topped up system pressure, but as soon as you put heating on, the water has nowhere to expand to, so blows off through the PRV which gets dirt on the seals. If you pressurise the system, without running the boiler for heating or hot water, does it hold pressure? If it's losing pressure and the vent pipe from PRV isn't dripping water, then it would seem a leak in pipework. Not sure about Heat exchanger leak - I would think that would leak water out of the boiler casing itself? [/QUOTE]
