A bathtub drain and overflow assembly diagram, illustrating the installation of a tub drain system. The image shows the plumbing connections that allow water to drain from the bathtub and prevent overflow.
Key Components: Overflow Drain (Top Section): The rotating connection allows adjustment to fit tubs of different depths (17 to 22 inches). The control knob and linkage (E, F) manage the stopper mechanism. Drain Pipe Assembly (Bottom Section): The drain fitting (K) connects to the tub bottom. The waste pipe (horizontal) connects to the main drainage system. Seals and washers (O, I) ensure leak-proof connections. Trap Connection: The lower section connects to the home's drainage system, typically leading to a P-trap. Purpose: Prevents water from overflowing the bathtub. Allows controlled drainage when the stopper is engaged or released. Connects to household plumbing for proper wastewater disposal.
