I need help in replacing the expansion vessel of my EVC13 home heating system.
The vessel is licking air, each time I refiled it takes just couple of hours and it's empty again.
Firstly, I need a suggestion where to buy a replacement tank here in Sweden, I found one online in the UK but it would be better if I could get it locally.
Secondly,I need some sort of a procedure on how to replace the old with a new working expansion vessel.
Attached are some pictures of the system.
I will deeply appreciate any suggestions.
Thank you all in advanced
