Old Story-New Problem!
This house was built in 1985, in need of many repairs. The kitchen sink has caused problems in draining over the past 5 years. One time, a plumber did come and ran the machine to clear the lines.
Every once in a while, I will see the double drains start to back up as I run the disposal. For the past three days, I have been trying to fix the problem myself. Draino for two days, w/hot water. The drains went down and w/i an hour slowly the sinks started filling up about a 1/4 of the depth.
Finally, purchased the lye product 18 hrs. ago, which I had success with several years ago. Now, the sinks are half-full of water and no success in draining them. I have plunged. I put the cloth in the disposal-attached side.
I cannot use the d/w and I have a counter full of dishes, plus the machine being full. The garbage disposal is not used for food anymore. I just run it to keep it clean.
How, can I fix this sink? What causes the issues? The toilets are flushing w/o back-ups.
