VRLB Drain Pipes sheet M-1.pdf

This document is a technical schematic drawing depicting a plumbing system design, specifically a sanitary drainage and venting system layout.

The drawing illustrates an isometric view of a multi-section piping system with multiple sanitary tee fittings (STTY), long turn tee fittings (LTTY), clean out locations (C.O.), and vents through roof (V.T.R.) connections. The system includes a combined vent run (indicated by dashed lines) that allows multiple vent lines to merge before penetrating the roof. According to the notes, the drain pipe is Schedule 40 PVC with a nominal diameter of DWV (Drain, Waste, Vent), and vents may be combined before roof penetration. The symbol legend identifies all key components: sanitary tee fittings, long turn tee fittings, clean out locations, vent through roof penetrations, and combined vent runs. The schematic demonstrates proper drainage routing and ventilation strategies for a plumbing installation, with measurements and connection points marked throughout the isometric representation. This appears to be a technical specification document or building plan component rather than a procurement solicitation document.
