quick question having got into this plumbing lark I was chatting with a friend he has a combi and the diverter valve was a diagnosed fault.
I thought if you had to take off the boiler casing you had to be rgi and as the diverter is within the boiler this would be the case. He says not as gas is not involved in this part?
