The WATCO 48500-bz is a push-pull single-hole drain trim kit finished in oil-rubbed bronze, designed for bathroom sink drain assemblies. The kit replaces or upgrades existing drain trim on single-hole sink configurations, using a push-pull mechanism to open and close the stopper without a lift rod. Components include a brass body, brass stopper assembly, 3/8-inch and 5/16-inch brass pins, metal overflow plate, adapter bar, mounting screw, and silicone adhesive. Plumbers and bath fixture installers working on residential bathroom sink drain replacement or upgrade projects will find this kit self-contained and ready to install.
This trim kit is suited for residential bathroom sink drain applications where a single-hole mount is required. The oil-rubbed bronze finish coordinates with a wide range of bathroom fixture finishes. The push-pull stopper operation eliminates the separate lift rod assembly found on standard drain configurations, simplifying the drain system and reducing the number of moving parts in the drain line.
Designed as an OEM-style replacement or upgrade trim kit for residential bathroom sinks with a single-hole drain mount configuration.
Installation is typically performed by a licensed plumber or experienced tradesperson. Shut off water supply and clear standing water from the sink basin before beginning work. Use the included silicone adhesive per the kit instructions to ensure a watertight seal at the overflow plate. Follow all applicable IPC and local plumbing code requirements for drain assembly installation.
