I am getting large bubbles in my toilets. Shortly after the bubbling starts water and sewage begins backing up into my shower stall and bathtubs. What is the problem?:confused:

Is toilet on 1st floor or 2nd floor or basement..

If in basement then most likely your main drain line is clogged and will need to be snaked out (look for main drain cleanout on street side of basement.. here you should unscrew cleannout cover and test by flushing toilet to see if main clogged)

If on 1st or second floor... you will probably need to lift the toilet and snake the drain line through that... clearly the main line to the bathroom battery is clogged. I am guessing that something got down that toilet and you are better off trying to pull it back rather than force it down drain... babyboy did you say... Hmmm??

However, if push forward is all you end up doing then try to force it forward down to the main drain cleanout described earlier. BUT first, try a retrieving head on snake if you rent a snake... hopefully you can pull back with this.

Let us know if you need help regarding lifting/installing toilet and/or how to snake drain, etc. GOOD luck. If this helped please RATE THE ANSWER below. Thank you!
