SPECIAL ORDER ITEM. Review Returns Policy before purchase. This PVC reducing tee fitting is designed for use in drain, waste, and vent (DWV) piping systems. It enables the transition from a larger main line to smaller branch lines, supporting efficient gravity-flow drainage without the need for pressure sealing. The fitting’s PVC construction provides corrosion resistance and long-term service life in non-pressure applications. Suitable for residential and commercial drainage installations requiring reliable flow direction and reduced piping transitions.
