For those of y’all who have been following my bathroom soap (literally) opera, my bathtub is stopped up again. 
What can I be doing wrong? Too much TP? I had a tub installed, could they have done something wrong, not attached the neck pipe to the shoulder pipe? Small rodents climbing up the sewage pipe and dying? Any ideas on what I can do? Would Draino down my toilet hurt anything? Can I get a snake? Do you think it would help?
I guess I’m calling Roto-Rooter. Again.
