Okay, I don't know how common of a problem this is but I need to give it a shot before I call a plumber, because I simply don't have the money to hire one at the time. I've got a 2 story house with one bathroom on each floor. When the upstairs toilet is flushed, stuff is coming up the downstairs toilet. Also, when the downstairs toilet is flushed, some of the time it won't go down, or it will go down very slowly, and it leaks. On a side note, the shower also backs up, and there would sometimes be a good 3 inches or so of standing water in the tub after I'm done taking a shower. I've tried drano and such to no avail :confused: . Much help is needed and appreciated! Oh, and in case it helps, the house is with septic. Not sewer.
