Today is the FIRST time I have ever experienced this.
This morning I noticed that there was sewage (fecal matter and toilet paper) all over the inside of my downstairs shower and some on the floor. Whatever happened, it must have been explosive! I don't recall noticing this last night!
I worked on clearing this clog all day without any success, except getting more toilet paper to flow out of the shower drain and into the basin. It seems as if the drain will drain VERY SLOWLY over the course of many hours.
If I use the sink in this bathroom, it will back up into the shower. The toilet is also clogged, but if I plunge it, it seems to also come up into the shower. If I plunge the shower, the toilet will bubble and gurgle. The downstairs floor where this particular bathroom is located is on a concrete slab.
I do not believe that this is a main sewer line clog, because the BASEMENT, one floor beneath this bathroom, also on a concrete slab, drains perfectly from the wash tubs. I actually washed a load of clothes today while this clog was in effect and didn't have any backup into the wash tubs in the basement, in which the washing machine dumps into.
Also, the center floor kitchen sink is not clogged, and the upstairs bathroom toilet, tub/shower and sink are also not clogged.
It seems to be limited to this one bathroom.
I live alone, and I am not sure what would have caused this issue to erupt between last night and this morning. I NEVER use the downstairs shower, but I will occasionally use the toilet down there, but not very often. I recall using the downstairs toilet a few days ago without any issues.
Any suggestions or tips? I attempted to snake the shower drain, but my snakes are garbage and I threw them away. I need to upgrade my snaking equipment, but to be honest, I never had to snake a drain before! I also poured about 3/4 gallon of Draino into the tub drain with virtually no result.
I scooped out much of the toilet paper and fecal matter that backed up into the downstairs shower as well. It seems as if the flow of toilet paper is done. Now, only brown water backs up into the shower basis, no more toilet paper.
