I have a ferolli HE31C and it has developed a water leak that appears to be from a porous casing in the gas valve. I can not see where water even enters the gas valve as I presume the gas goes in the bottom and out of the top of the valve. To check this out I dried it off and put some sealant over the pourous part of the housing and sure enough the the leaking water turned white. There are no drips above the gas valve at all. It would be great if somebody could tell me if this is possible. I am talking about the valve that has a clear tube at the top which goes up towards the boiler. It is the gas valve on ebay, there are lots of them for sale
