Why is it not recommended?
2 questions really...but still about incompatibility. I'm putting in a new drain and popup in a bathtub. ABS drainage at this place, chrome plated brass drain.
Why does typical pipe dope say do not use on plastic pipe yet the drain makes no mention of it. They just say coat the threads with pipe dope, put a bead of putty on the tub under the flange and screw the flange into the drain trap. They must know that both ABS and PVC are commonly used in DWV systems.
I see both Oatey and Rectorseal make dope specifically for ABS...so guess I'll pick some of those up.
Also, will regular putty be bad on a FG tub? I see the same type of warning on that. Use the non-staining oil free they say. Of course that's almost twice as much.

I had a similar thing happen last week. Fiberglas shower stall base. Instructions say use Silicone to seal the drain to the base, then the rubber washer underneath. It came with a yellow sheet stating NOT to use silicone, but to use an acrylic sealant. SO hopefully doing as the yellow warning sheet said will give good service.

Plumbers putty can degrade certain plastics over time, it can also permanently stain granite.
I wouldn't be concerned using it on ABS pipe, although it's not needed. Teflon paste on the threads is better.
The most important place to avoid putty is on a pop-up in a Cultured Marble sink.
The area around the sink drain will start to get spider cracks and veins over time.

Yeah, I knew about the marble and natural stone thing. I wound up using RectorSeal T PLUS 2 and Oatey non-staining putty. Which is all HD had.
Whoever originally did it didn't have the ABS drain lined up exactly with the hole in the tub. I imagine they got around it by screwing the drain body in, THEN attaching the surround and tub to the walls. Little harder after the sheetrock is up and the house is finished. On a a slab so no going in a crawlspace to push it over a bit. 1/8" can be a real pain in the rear sometimes. Gawd I hate plumbing, esp old work.
