OT: plumbing epoxy liner (instead of replacement)
we have a 2nd-floor drain-pipe from bathroom sink that has failed. 50 year old house, the 3" copper drain pipe now has very thin walls. a prior repair used a rubber splice w/ hose-clamps and the walls eventually thinned enough from corrosion that they crushed after 17 years.
i tore into the ceiling and cut out 6" of copper to see what i had to work with and the side-walls are pretty thin, something like 0.5mm left. if i were to do a similar splice fix, if it didnt collapse immediately i'd only kick the can down the road a couple years.
to replace the entire horizontal 8' run of copper w/ PVC, would require ripping out ALOT of plaster ceiling and wall. ALOT. not keen on that.
but i've learned about this epoxy pipe lining...seems like the perfect solution...clean out the drain-pipe, maybe solder in a copper stub where i've cut to give it some strength for the hose-clamps, apply the epoxy seal-coating, then install the rubber splice w/ hose-clamps as before.
anyone had this epoxy stuff done? i have a couple contractors coming out tomorrow...it'd be nice to go in with a bit of intel/experience.
