We just purchased a home and it needed a new garbage disposal. I called and had one installed and it worked fine for the first few times, then suddenly the sink backed up on both sides. Also, when the dishwasher runs, it backs up. The other drains in the house seem to be fine including the washer which is next to the kitchen. The garbage disposal drips under the sink when this happens too. I called the people that installed it and they said I must have a clog in the pipe so they came out and used a ballon looking thing to “clear” the pipes. Well, again the disposal seemed to work and after 1-2 times, it’s all backed up again. They only “balloned” the line that has an “outlet” under the sink, not a part of the sink pipes. Could it be something in the pipes directly under the sink? Why is this only happening now that the new garbage disposal has been installed? Any help/idea is appreciated! Thanks!
