The MUELLER STREAMLINE 5215 is a 1-1/2-inch PVC DWV hub union P-trap without a cleanout, designed for non-pressurized drain, waste, and vent applications. It is manufactured from ASTM D2665, F1498, D331, and D1784 compliant PVC, delivering strong chemical resistance and dimensional consistency. Hub-by-hub end connections allow for standard solvent-weld installation. The smooth interior wall minimizes scaling and promotes unobstructed flow. Licensed plumbers install this fitting in residential and light commercial drain systems as part of code-compliant DWV assemblies.
This P-trap is suited for non-pressurized DWV piping systems at a 1-1/2-inch pipe size, which is a common size for lavatory, utility sink, and similar fixture drains. The union feature allows for easier trap removal and service access without cutting into the drain line. This fitting meets NSF 14 and UPC standards, making it acceptable in jurisdictions that require listed DWV fittings for permitted work. It is appropriate for both new construction and repair-and-replace plumbing projects.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2-inch non-pressurized PVC DWV piping systems meeting ASTM D2665, F1498, D331, and D1784 material standards.
Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off the water supply and verify the drain line is clear before beginning work. Use only PVC solvent cement rated for DWV applications; prime and cement hub connections per manufacturer and code requirements. Do not use this fitting in pressurized supply lines or above its rated non-pressurized DWV application.
