I’ve got a clogged sink, and have been reading the labels on a bunch of different products lately. I’d always assumed that they were a strong acid of sorts, which would dissolve whatever sort of material was built up in the pipes. But I’ve noticed that a lot of these products specify that they’re non-corrosive, so I’m not sure what other sort of mechanism may be at play here.
You can also unscrew it though.
but why would I if I can just snake it?
unscrewing it I have to clean up everything afterwards. I also have to patch the ceiling or re-cover the access hole.
with a snake, I just snake it. it goes through the plumbing, and I’m done.
unless I’m missing something.
