Your very welcome.
About “invasive architectural changes” God do I know where your coming from.
Here in the big apple a lot of my accounts are brown stones well over 125 years old with works of art like inlaid wood ceilings and marble bathroom floors.
The name of this game is try to keep everything in the original condition.
OK now in this case get Hercules Propoxy and using water while working it you can fill small voids and also build up a large gap with no chance of doing any smoke or chemical damage.
The key is removing as much scale build up as possible.
I have seen “jobbing” plumbers use this product on lead/steel/cast Iron and all ferrous and non ferrous piping including steam systems.
The epoxies of today are a lot stronger then the base materials and do not shrink or peel or burn.
If you want our more then welcome to send me a private E mail as I a lucky to have on my list not only chemists working in the plumbing field but several Licensed plumbers who are also professional engineers.
We kick these kinds of problems around constantly looking for the best possible approach for each job.
Working and keeping these older systems going is a real challenge and fun as it keeps you active.
The best heating job I have worked on was a steam system in NYC with 15″ steam mains and get this 7″ condensate piping.
Talk about trying to keep a system going.
TRY securing 7″ pipe today.
You have to call these older houses on a per job basis and knowing you don’t have the luxury of simple replacement.
Good luck and the main thing is be happy
