In response to Re: Toilets upstairs and on main floor
If the upstairs toilet was an addon and the lower one was not properly revented during the process, that will happen. The initial flush water will cause a positive pressure that will force air out of the lower toilet, and then as it goes past that toilet's opening it will create a vacuum and suck the water out of the toilet.

: When the toilet upstairs is flushed, the toilet on the main floor gurgles and blurps and basically almost flushes itself. What causes this? My house is over 50 years old and still has cast iron pipes in the basement. Could this be part of the problem? We have a septic tank and well water. Any ideas/suggestions?
