Me again with another theorical question...
Please take a look at the drawing...
At the end of the 15' drain there is the main stack.
What if at the 'x' mark there would be something blocking the flow... both the shower and toilet would not be able to empty themselves.
The water inside the toilet bowl it at the brim. Now... say I flush the toilet once more... would the water trying to leave the toilet backup inside the shower stall?
Thanks again!
