Matco-Norca has expanded its line of DWV (Drain-Waste-Vent) plumbing specialty product offerings by introducing a new DWV Wye and Trap Adapter, both in cast brass. DWV system elements remove sewage and greywater from buildings and regulate air in waste system pipes, facilitating flow. By maintaining neutral air pressure in drains, gravity moves water and sewage flow down drains and waste pipes. Matco-Norca’s DWV Wye is available in 1 1/2” and 2” C x C sizes. Its new DWV Trap Adapter is available in a 1 1/2″ SWT x Slip configuration. The new wye and adapter supplement existing Matco-Norca DWV products such as a Dandy Cleanout Tee (1 1/2″ and 2”) with Plug and similarly sized Trap models, with cleanout and less cleanout options.
