This diagram illustrates a basic installation of a 1.5-inch PVC vent and drain system for a sink, routed within a framed wall. The key components include a 1.5” PVC sweep (long ell) connecting to a trap adapter, which links to the 1.5” santee fitting. From there, the drain continues horizontally, while the vertical branch rises as a 1.5” vent pipe. This clean and compact configuration meets common code requirements for residential sink drainage and venting. The long sweep elbow ensures a smooth transition of wastewater with minimal turbulence. The santee allows a dual connection—one for drainage and one for venting—essential for maintaining the trap seal. This setup is frequently used in bathroom vanities or compact wall cavities where horizontal and vertical transitions must be contained within stud spacing. Its labeled clarity makes it a reliable visual reference for rough-in plumbing work.
