POP-UP Waste Coupling 32 mm (Full Thread)

Description

A pop-up waste coupling is a type of drainage mechanism commonly used in bathroom sinks. It consists of a stopper or plug that can be raised or lowered by a lever or a knob on the faucet. When the stopper is lifted, it allows water to drain from the sink, and when it’s closed, it prevents water from flowing down the drain.

Here’s how a pop-up waste coupling generally works:

Stopper Mechanism: The stopper is attached to a horizontal rod that runs through the faucet body. When you push or pull the lift rod (usually located behind or on the faucet), it moves the horizontal rod.

Pivot and Seal: The horizontal rod is connected to a pivot located beneath the sink. As the rod moves, it causes the stopper to pivot, either opening or closing the drain.

Sealing Function: When the stopper is in the closed position, it forms a seal to hold water in the sink. This is particularly useful for tasks like filling the sink with water for washing or shaving.

Drainage: When the stopper is lifted, it pivots to an open position, allowing water to flow down the drain.

Pop-up waste couplings are popular in bathrooms because they offer a convenient way to control water drainage. The design also provides a sleek and streamlined appearance to the sink area, eliminating the need for a separate stopper or plug. Regular maintenance is important to ensure proper functioning, as hair and debris can accumulate around the pivot and affect the drainage system.
