Hi All, A quick and hopefully simple question: I have recently had to drain down my combi boiler system to re-pressurise my expansion vessel - all done fine now! Of course, now I have refilled with fresh water, I have diluted any additives, protectors that were in the system - and since...

Ok, Certainly after draining down the system and pumping the vessel to 12 PSI I can then drain more water out and repeat, and again, and again... Finally, the system pressure gauge remained at 0 when I had 12 PSI in the vessel. I left the foot pump attached for 10 minutes and the expansion...

:oops: I think I missed this point from the re-pressurising instructions... During this phase it is IMPERATIVE that water or air is allowed to escape from the heating system as it is pumped out of the PV. Otherwise the system pressure will resist your pumping and give a meaningless...

Hi All, My first post but I have observed for quite a while! :) I have a Vokera Linea 24 which I think I have now proved has an expansion vessel problem. The same old symptom - loss of pressure in a short period of time (approx 1 - 2 days now heating is in use). I drained the system...
