Hello there,

I had three quotes to have a combination "Condensing" boiler fitter. First
two looked it and said fine and provided price. However, the last guy and
the one who I liked most said I cannot have a combination condensing boiler
as I have a cast iron waste pipe which is shared with the whole flat (I am
on top floor of three story flat). He said the high acidic content will rot
the sewage pipe and I am not allowed.

No one else mentioned this! Even the inspector (it is an ex authority
property) who visited for other aspects did not mention this (although he
was not particular an expert).

Looked on the internet and cannot find any mention of this. Anyone else
heard this?

Kind regards
Dave
