Basement toilet splashes when 2nd story toilet flushes
Posted by Jason on February 06, 19100 at 22:09:12:
Please help! My house is a colonial with 1 bath upstairs and a toilet in the basement. When the upstairs toilet is flushed, air pressure backs up into the drain for the basement toilet, causing water to splash out of the bowl. I've had the house's main drain line snaked a couple of times in the last two years and replaced the basement toilet. Still have the same problem. Does anyone have an idea about what might be causing this?
