sink in garage
i installed a sink next to my washer , tied drains together, i think i did right, but i get water in the sink and some times i get water that comes up in kitchen sink, can someone please tell me what i might have done wrong.
we fixed this by going to the main water outlet pipe on the side of the house. we opened it up, cleaned out all the vegie scrap that didn't get chopped up properly by our garbage disposal & the back ups stopped. our garbage disposal, at times, doesn't do what it's supposed to do or the human operators don't do what they are supposed to do so all of the refuse just clogs up the pipes.
