Always call in a certified plumber for serious drain issues, plumbing repairs and replacements. Some plumbing problems look like a quick fix, but even the avid DIYer may end up doing more harm than good. If you have any doubts about how to proceed with a plumbing issue, seek professional help. Using improper equipment or even proper equipment without the technical know-how can exacerbate a minor blockage into a damaged or broken drain system.
