Toilet and bathroom sink backing up into shower.
Hello, first off, my house was built in the 1930s. About four nights ago someone flushed about 6 or 7 nose tissues down the toilet, causing a clog. The following morning when I was taking a shower I noticed that the water was barely going down, if at all. On the same day I went to ace and bought a 20 foot snake; I successfully removed a fair amount of the tissues, and the toilet began to flush normally. However, whenever I flush it some water rushes up the shower drain and enters my shower (dity water). I attempted to snake the shower, and I actually removed a decent amount of hair. However, the shower remained backed up. I also bought a drain cleaner that specialized in hair. This did also not work.
Currently, the toilet is working normally, as is the bathroom sink, however, the shower drains only very, very slowly, and water continues to back up whenever I flush the toilet or use the sink.
Thank you so much for your time.
