Elkay Residential LK373 Sink Drain Removable Standpipe

Product Description

The ELKAY RESIDENTIAL LK373 is a 3.5-inch sink drain with a removable standpipe, constructed from Type 304 stainless steel on both the body and tailpiece. It is designed for kitchen, bar, and laundry sink applications where a reliable, corrosion-resistant drain assembly is required. The removable standpipe measures 6.625 inches standalone and 5.25 inches when assembled, allowing straightforward removal for cleaning and maintenance. A 1.5-inch outer diameter tailpiece measuring 4 inches in length fits standard residential drain rough-in configurations. An included O-ring rubber stopper seats firmly to prevent leaks and maintain drainage performance. Licensed plumbers and qualified installers handle this fitting in new construction and replacement work.

The LK373 is suited for residential and light commercial sink installations including kitchen sinks, bar sinks, and laundry sinks. The removable standpipe design is particularly useful in utility and laundry room applications where the standpipe must be cleared for cleaning or serviced periodically without disturbing the drain body. The 3.5-inch drain opening and 1.5-inch OD tailpiece align with standard sink knockouts and trap arm configurations common in residential plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and ensure the sink basin is empty and dry before beginning work. Do not overtighten the drain locknut against the sink deck, as this can crack sink material or distort the drain flange. Verify the O-ring is seated correctly before completing the assembly to ensure a proper seal at the stopper.
