Toilets upstairs and on main floor
Posted by Kathleen on December 02, 2003 at 20:53:38:
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?
