The MUELLER STREAMLINE 5825 is a 4-inch PVC DWV hub wye fitting designed for drain, waste, and vent piping systems in residential and commercial construction. The 45-degree angle configuration directs flow smoothly through the branch connection, reducing turbulence and the risk of blockage. PVC construction provides strong resistance to chemicals and corrosion, and the smooth interior walls minimize scaling buildup for consistent, unobstructed flow. All three connections are hub-style, accepting standard 4-inch DWV pipe. Plumbers and pipefitters install this fitting as part of sanitary drainage and vent assemblies where a 45-degree branch takeoff is required.
This fitting is suited for residential and light commercial DWV applications including sanitary drain lines, chemical waste systems, and vent piping where PVC is the specified material. It conforms to NSF 14 and UPC standards and meets ASTM D2665, F1498, D331, and D1784 material specifications, making it appropriate for code-compliant installations in jurisdictions that accept PVC DWV systems. The hub x hub x hub end connections are sized at 4 inches on all three ports.
Designed as an OEM-style replacement and new-installation fitting for 4-inch PVC DWV piping systems conforming to ASTM D2665 standards. Suitable for industrial, sanitary, and chemical-resistance drainage applications where PVC hub fittings are specified.
Licensed plumbers install PVC DWV wye fittings using PVC primer and solvent cement per ASTM D2564 and applicable IPC or UPC code requirements. Shut off water supply and ensure the drain system is depressurized before cutting into an existing line. Do not use open flame near PVC fittings or solvent cement. Allow adequate cure time before restoring flow, following the cement manufacturer's published schedule for the ambient temperature at the job site.
