When you flush the upstairs bathroom toilet there is what seems like bubbles of air coming up through the water in the basement toilet. Then when the basement toilet is flushed water leaks around the base of the toilet - a lot of water.
any ideas what is happening?
When you had the upstairs toilet removed, did you plug the hole with a rag or something?
If so, maybe you forgot to remove the plg and when you first flushed the new toilet, the plug washed down and plugged the downstairs toilet!
