Hello helpers and others like me(in need of help),
The attached diagram will explain the general situation but the core question is this: I am concerned there is a possibility of toilet waste making its way into the basement floor p-trap, if the wye it's connected to is in perfect horizontal allignment with the main pipe.
The main pipe will have a 1/4" per foot drop, but if a piece of solid hangs just past the wye, isn't there a chance some fluid may back up into the trap?
Can the wye be rotated 1/8 from horizontal, then add a 1/8 bend before attaching the p-trap? (this would raise the p-trap slightly but I still have room under the concrete).
Bottom line, what's the right way to do this?
Regards, Greg
