Thick, greasy looking, jelly stuff in the drain pipes?
Just a quick question if anyone know the answer. Our house was built in 1998, we bought it about two years ago. The other day, I was installing a garbage disposal under the kitchen sink and had to re-do the drain pipes under there.
Anyway, when I took the drainpipes apart underneath the kitchen sink, they were about 50-60% clogged with a black/brown, greasy-looking, jelly type stuff that was just real nasty. It smelled kind of like sewage, not real strong but definitely stinky.
Is this normal? I dug out what I could and replaced most of the under-sink drain pipes. I just didn't know if this is normal.
