Hubby was using his electric auger to clean out our kitchen sink drain. We have a clean out opening under the sink. So that is where he ran the auger. He got it about 5 feet down the drain, and it got stuck. He thinks the snake kinked while in the pipe. He pulls with all his might and some of it comes out, but won't go any farther. As soon as he lets go, it zips right back into the pipe. I did some research online. A plumber was saying that when this happened he used a come along. The line snapped and nearly killed him. Years ago we had a plumber replace some of this same line. He put in the clean out for us. I watched what he did. He replaced about 3-4 feet of rusted metal pipe with PVC. Where he joined up the PVC with metal, he used one of those rubber sleeves held in place with hose clamps. I suggested to hubby that we open the wall where this repair was made. Remove that rubber sleeve. It should put us very close to where the auger is stuck. Does anyone have any suggestions that don't involve tearing out drywall?
