POP-UP DRAIN VALVE STOPPER WITH STRAINER CUP

摘要

A pop-up drain valve stopper has a lower portion that is retained in a drain pipe through which liquid passes while exiting the bowl of a sink, and an upper portion that is easily disconnected from the lower portion and withdrawn from the drain pipe so a strainer cup carried by the upper portion can be cleaned or replaced as needed. In one embodiment, the strainer cup is an integral part of the upper portion. In another embodiment, the strainer cup can be detached and cleaned or replaced when it has caught a volume of hair and foreign matter. A threaded connection or equivalent may be used to releasably couple the lower and upper portions. A twist connection or equivalent may be used to releasably couple the strainer cup to another part of the upper portion.
