Hi all,
I have a Biasi combi boiler m90f.28s, its slowly losing CH pressure in the last few weeks. The loss in CH water is about 0.4bar per day. The external system is ok, can't find any leaks.
At first, thought it was the heat exchanger because when it had its service back in November, there was green (copper sulphate) on the fins. Its still there, but there isn't a leak, had it off all day to see.
Also in Nov, I serviced the 3 way div valve - it leaked so I dismantled it and re-greased it, it works great and no leaks.
Today, I found, after i put a bottle under the safety discharge pipe, about a cup full of water - it seems to be a leak from the pressure relief valve.
Can anybody describe how this can be fixed?
What are the short term problems with this fault?
Thanks for your help in advance
