Jack up the sink???? the pipes hold it up???? my goodness...this is all wrong...all wrong...(I say pacing the floor trying to think of a way to help)...OH I no call a plumber one that knows how to fix this problem...
how old is your house/plumbing....if its old you can make the clog worse with drainOH No I have ruined the plumbing!
try a plunger...it will work on sinks too....put water in the sink first to push some into the drain...if you know how to get the stopper out do that first...
Did all that already.
I need to take the pipes apart at the U. That's where my problem is.
