Help Please!! My kitchen sink is clogged. I have a disposal on one side. Both sides back up. I’ve used Liquid Plumr and it hasn’t worked. When I start the disposal the water seems to go to the other side of the sink but then comes back when I stop the disposal. Has anyone had this problem and how do you fix it.
Undo the waste trap under the sink and the garbage disposal unit and clear the blockages. Check the drain pipe from the traps to the end outlet is free from blockages – use a flexible wire drain cleaner from the outlet end.
