Frequent toilet stoppages can indicate a couple of things: 1) there are one or more members of the family who don't know what NOT to put into the toilet, or 2) a partial blockage exists somewhere down the line in your sewer that has a tendency to easily clog. Without having someone perform a thorough cleaning you might never find the problem. Sewer cleaning doesn't require removal of anything (flooring, walls, etc.). Ordinarily, it can be done at an opening known as a "cleanout". Unscrew the cleanout cap and pressure wash or "snake" the entire line with a tool of the same name _ a plumber's snake. You can do this job yourself but a snake that is large enough to do the job is also big enough to destroy your sewer system in the hands of a novice. We suggest a professional. In the long run you'll save. Once everything is operating properly, give your whole family a lesson in toilet hygiene. Nothing, absolutely nothing should go into a toilet except waste and toilet paper.
