Minor sewer backup - how to clear clog between shower and toilet
This past week, while using the basement shower, the toilet would bubble but I didn't know what that meant. Well, this morning, same thing, but then the shower wouldn't drain so I stopped the water - then continued my shower but noticed a rotten egg smell - the sewer line backed up! We have run water through the basement bathroom sink, the kitchen, and the main floor bathroom and kitchen - all of those are okay so we don't think the issue is in the main house drain. We think it's between the toilet and the shower in the basement. Is there a homemade approach we can use to get rid of this problem before we call Roto Rooter? We've run industrial strength drain cleaner down the shower and the bathroom sink and have flushed the toilet but it still backs up.
I saw that another reply suggested putting bleach in the shower drain overnight, and then flushing it with hot water the next day. Is that a good approach? Any suggestions would be great! Thank you!
