My bathroom tub is constantly plugged up I have had plummers here to run a snake through to clear it out ,this last for about 3or4 months and the same problem is back again.we had new tub insert install 2 years ago I do not know if this the problem or not .the few handymen we had look at thinks the pipe running from tub to main drain is the problem and needs to be relaced how ever this under a ceramic tile floor in the bathroom,or p ossibe acess from bedroom ceiling downstairs. We need help what's your best solution;;

Hey RC,
Before we can find a solution we must know the cause of the problem. Since this has been a ongoing problem I have a hunch that you have backfall on the tubs drain line causing your backups. The only way to tell is to open up the ceiling a way and put a level on the pipe. If you have back fall the pipe may be raised at the tubs trap to give it pitch. That way you wouldn't have to tear up either the floor or the ceiling.
Good luck and thank you for rating my answer. Tom
