i will explain as briefly as i can
remodeled an old bathroom, top floor, directly over dining room - no walls available to run pipes. the main outside wall down below is a 15' wide french door/window combo
added a bigger tub (used to have standard size), explanded bathroom into closet next door to "bump" tub back a few feet give some more room.
now main stack is in one corner far corner from tub, right next to toilet. so the drain for the tub must run all along the floor, collectting the sink drain as it goes, hang a 90 turn in the wall and continue along to the main stack. total run from tub to stack is probably 12' (8' run + 4' after the 90 degree turn). i added a vent at the sink, a vent at the tub and a vent at the 90 degree bend in the pipe. the drain pipes and vent pipes are all 1 1/2" abs.
after the 90 degree bend the pipe turns into cast iron, i think it is 1 1/2 inch, the main stack is cast iron as well.
the main drain is also low slope, as this entire span must fit in the floor - all of about 8" of space.
now the bathroom is finished, tiles are down and the tub drains like crap. takes forever to empty the tub, and the sink flows back into the tub. the toilet works great, but its only a foot from the main stack.
i have no idea what to do
HELP!
