The MUELLER STREAMLINE PDWVCOT2 is a PVC test tee with a clean out plug, designed for use in drain, waste, and vent (DWV) piping systems. The fitting connects two hub ends to a cleanout opening, allowing plumbers to access the line for inspection, testing, or clearing blockages without cutting into the pipe. At 2 inches on all three connections, this tee fits standard residential and light commercial DWV installations. Licensed plumbers install this fitting during rough-in or as a service access point in an existing drain line.
This fitting is suited for residential and light commercial DWV applications where code requires accessible cleanout locations. Typical install scenarios include horizontal drain runs, stack bases, and branch drain lines where periodic maintenance access is needed. The included clean out plug seals the opening during normal system operation and during pressure or air testing of new DWV rough-in work.
Designed as an OEM-style replacement or new-installation fitting for 2 inches PVC DWV piping systems following standard hub connection dimensions.
Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Solvent-cement all hub connections using PVC primer and PVC DWV-rated cement, allowing full cure time before pressurizing the system. Ensure the clean out plug is fully seated and hand-tightened before conducting any air or water pressure test. Do not use this fitting on pressurized supply lines or outside its rated DWV application.
