Bsc Preferred LK373 Sink Drain Removable Standpipe 3.5 in

Product Description

The BSC PREFERRED LK373 is a 3.5-inch sink drain with a removable standpipe, built for residential and light commercial plumbing installations in kitchen, bar, and laundry sink applications. The body and tailpiece are fabricated from Type 304 stainless steel, providing corrosion resistance and long service life in wet environments. The standpipe measures 6.625 inches standalone and 5.25 inches in the assembled configuration, allowing a plumber to remove it easily for cleaning or maintenance. An included O-ring rubber stopper creates a reliable seal at the drain opening to prevent leaks during normal use.

This drain is suited for standard residential and commercial kitchen sinks, bar sinks, and laundry sinks where a 3.5-inch drain opening is present. The 1.5-inch outer diameter tailpiece is sized to connect with standard 1.5-inch drain plumbing, making it compatible with typical P-trap and waste arm configurations found in most sink installations. The removable standpipe design is particularly useful in laundry and utility sink setups where periodic drain access is required. A licensed plumber or skilled tradesperson would be the typical installer for this fitting.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and clear the drain line before beginning work. Plumber's putty or a gasket appropriate for stainless steel is typically applied at the sink deck flange to ensure a watertight fit. Do not overtighten the locknut against the sink basin, as this can distort the drain flange or damage the sink surface.
