I was using the waste disposal in the kitchen and when I went to the bathroom a few minutes later I had water coming up the drain.
The tub is now completely clogged. I have used drain and liquid plumber, but nothing is working.
I also noticed that if I use the sink in the bathroom, it is very slow draining and I have more water coming up into the bathtub.
Can this be fixed without calling a plumber? What has happened?
