Fixtures & Fittings

Sink drain P-traps are curved sanitary fittings governed by ASME A112.18.2 that maintain a 2-to-4 inch liquid seal barrier to block municipal sewer gases from entering living spaces. Sized in 1-1/4" tubular for bathroom lavatories and 1-1/2" for kitchen sinks, P-traps join via slip-joint compression washers and threaded slip nuts.

Toilet rough-in dimensions under ASME A112.19.2 define the exact centerline distance from the finished rear wall to the closet bolts on the floor flange. While 12.0 inches (305 mm) is the universal modern standard, 10-inch and 14-inch rough-in toilets accommodate legacy plumbing and thick tile remodels, sealing to a 4"×3" closet flange via a wax ring or rubber gasket.
