The CHARLOTTE PIPE 3751 is a Schedule 30 PVC reducing wye fitting designed for gravity-flow drain, waste, and vent systems. It features a hub end style on all three connections, accepting solvent-welded pipe joints. The fitting transitions a 2-inch branch inlet into a 3-inch main run, making it a standard choice for combining drain lines at a reduced branch diameter. Rated to 140 degrees F, this white PVC fitting is suitable for non-pressure sewer and storm drainage applications. Licensed plumbers and drain installers select this fitting for underground and above-grade DWV rough-in work.
This fitting is used in residential and light commercial sewer and storm drainage systems where a reducing branch connection is required. It is well suited for horizontal drain runs that need to accept a smaller-diameter tributary line without stepping up the entire run. Typical installations include under-slab drain assemblies, vertical stack branches, and site storm drainage piping where flow direction and grade must be maintained. The reducing wye geometry supports proper flow transition and minimizes turbulence at the junction.
Designed as an OEM-style replacement and standard fitting for Schedule 30 PVC sewer and storm drainage piping systems with hub-end solvent-weld connections.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local amendments. Shut off water supply and ensure the drain system is depressurized and clear before cutting into existing lines. Clean and deburr all pipe ends, apply PVC primer and solvent cement per the fitting manufacturer instructions, and allow full cure time before restoring flow. Do not use this fitting in pressure pipe applications.
