Lavatory Drain

Lavatory drains are plumbing fixtures and accessories that are used in bathrooms or lavatories to remove wastewater from the sink. They are part of the supply class Plumbing Fixtures And Accessories in the supply group Plumbing, Heating, And Waste Disposal Equipment. Lavatory drains typically consist of a drain assembly, which includes a drain pipe, a drain flange, and a drain stopper. The drain pipe connects the sink to the plumbing system, allowing water to flow out of the sink and into the wastewater system. The drain flange is the visible part of the drain that sits on top of the sink and provides a seal to prevent water from leaking. The drain stopper is a mechanism that can be opened or closed to control the flow of water down the drain. Lavatory drains come in various sizes and designs to fit different types of sinks and plumbing systems.
