Jay R. Smith Mfg. Co 3581 Sanitary Drain

The Jay R. Smith Mfg. Co 3581 is a cast iron sanitary drain built for floor-drain applications. Its Duco-coated body meets the ASME A112 standard and includes a replacement funnel for serviceability. The round shape and screw connection suit commercial and institutional plumbing installations.

Ideal for contractors specifying code-compliant

This drain suits projects that require a ligature-resistant fixture is not needed and where a screw-type connection fits the existing piping plan. Buyers who need a different pipe-size fit, a threaded connection other than screw, or a non-cast-iron material should look at other options.

6-inch overall diameter with 4-1/4-inch height

The 6-inch round body provides a wide inlet for floor-level drainage in high-traffic areas. The 2-1/2-inch overall length and fixed 4-1/4-inch height limit vertical adjustment, so installations requiring deeper rough-in or flexible height settings will need an alternative assembly.

What floor-drain fitting does the 3581 sanitary drain connect to?

The unit uses a screw-type connection designed for standard floor-drain installations.

Will the Duco-coated cast iron hold up next to older brass or plastic drain bodies?

How can I confirm the replacement funnel is seated correctly after installation?

The funnel should sit flush in the 6-inch round opening with no visible gaps around the perimeter.
