If you are washing your hands, rinsing sink after brushing teeth, etc., the sink fills up with water. Does anyone know why this would happen? The only thing I can think of is that water covers the entire opening to the drain, and air cannot escape when water tries to move in.I have tried liquid de-clogging products, which seem to work a little, but the pipes are PVC, and pretty clean. I disassembled them and checked.Thanks!
The stopper might need adjusting, the over flow might be clogged and sink can't breathe
