Why does the downstairs toilet bubble when the upstairs toilet is flushed?
Right now, sometimes when the upstairs toiled is flushed, the downstairs toilet bubbles. Not like it is going to overflow, just air that causes it to bubble.
Why does the toilet flush down the vent stack?
So, when the upstairs toilet flushes a large volume of water down the vent stack it forces air up through the toilet since it cannot go up through the AAV. The only really good solution is to add a vent to the downstairs plumbing that goes all the way to the attic and joins the house vent stack there.
What should I do if my upstairs toilet is Flushing?
There are several ways to do it; perhaps the plumber can install a Studor vent, an interior vent that equalizes the pressure in an unvented fixture and can only be used where there is a roof vent for the rest of the plumbing. We were unable to load Disqus Recommendations.

Why is water backing up in my Basement Toilet?
Twice I’ve had a blockage in the pipe from the house to the septic tank and water from the floor above backed up in the basement toilet because that’s the lowest fixture in the house. You may not notice anything wrong on the floors above (I didn’t). If it’s not a total blockage the basement toilet will drain slowly (mine did).
