Help! My toilet was clogged but then I unclogged it with the plunger so I thought everything was OK. Then, later, I was running water in the bathroom sink and heard a glob glob sound from the shower. Then, to my horror, the dirty, smelly waste was coming up the shower drain! I went back to the toilet and it is again going down slowly but still goes down. But, dirty water comes up in the shower when I flush the toilet or run the sink water. I ran to the store and bought some Rotor Rooter Clog Remover that says it's safe for all plumbing. I used it but still have the problem. Then, I went back to the store and bought a snake but that didn't work either. Any ideas? I have very little money to work with at the moment. Thank You so very much.
