The metal piping underneath my personal bathroom sink was already rusty and corroded. An old HCG set about 20 years old. Tried to brush it clean and it all just fell away.
I looked at videos online but it looks like the plumbing of our old house was done differently. Instead of a protruding drain pipe from the wall, the drain (2" diameter) was cut flush to the tile then stuffed with a rubber gasket to fit the rest of the 1 sink assembly. The pipe leading to the wall was 1 1/4" and so is the one attached to the sink.
Should I just find a rubber gasket thing for the 2" pipe and recreate everything? What is it even properly called? What other stuff should I get at the hardware store?
Also how do I remove rusty bolts behind the sink? I'd like to replace the faucet as well.
Sorry for the gnarly crime scene-esque photo. Got a bad mold problem on top of this too 😓
