Washer Drain Plumbing Diagram - New 2" Drain with Studor Vent & Clean Out Plug

This is a simple hand-drawn plumbing schematic (not an automotive document) showing a proposed modification to a household washer drain system. The drawing depicts, in blue, an existing vertical vent pipe and an existing washer drain that includes a P-trap at the bottom, plus a clean out plug (marked with a black plug symbol) at the low point of the horizontal run. In green, a proposed new 2-inch drain line is shown rising vertically and topped with a Studor vent (an air admittance valve, drawn as a boxed fitting at the top of the new riser). The new 2" drain connects horizontally near the top to another green stub and ties into the existing horizontal drain line at the bottom. Two horizontal brown lines appear to represent floor/joist or wall framing levels that the pipes pass through. A reader can learn the intended routing of a new 2-inch drain with an air admittance (Studor) vent relative to the existing vent, existing washer drain and trap, and where the clean out plug is located. Despite being filed in a 2010 Hyundai Genesis gallery, the document contains no vehicle-related information whatsoever.
