I posted about this a number of months ago, but I think I may have
come up with a solution and was wondering a couple things.
First off, the story is this: I have a 1920s-era house with all
original fixtures. The shower in one of the bathrooms has been
leaking badly and I want to replace the valve assembly, which I've
already purchased. The problem is that the steel pipes that were used
are completely corroded and cannot be loosened. Yes, I know the best
solution is to replace it all with copper, but because the only access
to the pipes is through a wall of 1920s antique tile which is *NOT*
replacable, I am not willing, under any circumstances, to rip out the
wall to replace the showerhead line. I had a plumber friend come out
and look at it and he basically said the wall goes or it doesn't get
fixed. I replaced the valves and seats on the current assembly and it
worked for a couple weeks, but it seems clear that there is a crack
within the assembly that cannot be permanently repaired this way.
In the newest issue of Fine Homebuilding though, there was a way to
simply cut all the existing pipes and solder in couplers between the
old pipes and the new assembly. My question though is what is the
best way to couple the new copper assembly to the old steel pipes?
I've seen compression fittings for larger pipes, do they exist for
smaller ones as well? Any idea how well they work? Once I finish the
repair, I'm going to patch up the small hole in the wall with the few
remaining 1920s era tiles I have and don't want to have to open up the
