Fabricated DWV Fittings

Fabricated DWV (Drain, Waste, and Vent) fittings are custom-built components designed to handle non-pressurized drainage and venting applications in large-scale or specialized plumbing systems. Unlike molded fittings, fabricated DWV pieces are made to order, providing flexibility in unusual configurations or larger diameters not always available off the shelf. These fittings ensure smooth wastewater flow, proper venting, and compliance with plumbing codes in municipal sewer lines, commercial buildings, and industrial drainage systems. Because they are made from high-quality PVC, they resist corrosion, scaling, and chemical attack, making them a long-term solution for critical drainage infrastructure. Ray Lewis offers locally stocked standard DWV fittings and access to fabricated options, backed by expert support to help contractors select the right components for complex layouts or large-diameter installations.
