A toilet's drain must be run at 1/4 per foot minimum grade when horizontal. A toilet cannot be installed upstream of any wet vented fixture. The maximum vertical fall of the drain is 1 meter(39 inches) and the maximum horizontal run is 3 meters before it connects to a vent. All downstream drainage after the connection of a third toilet on the same horizontal pipe must be 4 diameter or larger.
Bathtub drain rough-in. The standard bathtub/shower combination will require an 1-1/2 drain and p-trap installed to your local plumbing code. The drain must be graded(sloped) at a minimum of 1/4 per foot and must be vented. This can be done in one of two ways, by wet venting the trap arm fixture drain or by individually venting the bathtub.
