The MUELLER STREAMLINE 5222 is a 2-inch PVC DWV hub-by-hub P-trap designed for non-pressurized drain, waste, and vent systems. The fitting uses a solvent weld joint for a secure, leak-resistant connection and is manufactured from ASTM D2665/F1498/D331/D1784-compliant PVC. Smooth interior walls reduce scaling and support consistent flow. This trap does not include a cleanout. Dimensional integrity and consistent material quality make it suitable for rough-in and finish plumbing work in residential and light commercial applications. Licensed plumbers and qualified plumbing contractors are the typical installers.
The 5222 is intended for non-pressurized DWV piping systems. Hub-by-hub configuration accepts standard 2-inch PVC pipe on both ends via solvent weld, making it compatible with conventional schedule 40 PVC DWV rough-in installations. It meets NSF 14 and UPC standards, confirming suitability for potable-water-adjacent drain and waste applications in jurisdictions that recognize these certifications. Typical install locations include under kitchen sinks, lavatory sinks, and similar fixture trap applications.
Designed as an OEM-style replacement or new-installation fitting for 2-inch PVC DWV piping systems using hub-style solvent weld connections in non-pressurized drain, waste, and vent configurations.
Installation should be performed by a licensed plumber in accordance with the applicable plumbing code, including IPC or UPC as adopted locally. Shut off the water supply and ensure the drain system is not under pressure before cutting into existing lines. Use appropriate PVC primer and solvent cement rated for DWV applications; allow full cure time before restoring flow. Do not use this fitting in pressurized supply lines.
