Really does a great job of saving the old fittings!
This really saved my bacon. The rotted out toilet flange under the floor went directly to a cleanout T, and then directly into 3 other pipes, all under the floor. Being able to ream it out and save it meant not tearing into even more of the floor then I had to. Would definitely recommend it. One proviso: It gets HOT after 5-6 minutes, and needs to cool to continue properly.
Was able to replace a cracked PVC drain line without jack hammering concrete. The house settled and a pipe got squashed right above a clean out T as it entered concrete floor. Would have been major expense to cut away walls and concrete. Thanks
