Clearing sink drain line
Posted by David G. Hood on August 26, 19100 at 22:27:13:
I have used a 25' snake to clear a 20' line from my sink to the point where the drain joins the washing machine drain. The washing machine drains fine, but the sink drain line plugs up as fast as I open it up. In fact, the snake seems to hang up when I pull it out. The line acts line there may be heavy debris in it. Small lumps of white material come out when I pull out the snake from the line. I also tried opening the line with a quart of concentrated sulfuric acid. Please help me with advice.
