Sloan 3983402 Regal Flushometer 1.6 Gpf

Product Description

The SLOAN 3983402 is a Regal series diaphragm-type flushometer designed for water closet (toilet) applications in commercial and institutional plumbing systems. Operating at 1.6 gallons per flush (GPF), this valve meets low-consumption flush requirements in compliance with federal and many state water efficiency mandates. The unit weighs 9.374 pounds and is intended for direct installation on flush valve rough-in connections. Licensed plumbers and commercial plumbing contractors are the primary installers for this type of valve in new construction and retrofit projects.

The Regal 940 series flushometer is a standard choice for commercial restroom installations in offices, schools, healthcare facilities, and public buildings. The XL designation and 2-10 3/4 LDIM specification indicate an extended outlet and dimensional configuration suited to specific rough-in and partition depth requirements. This valve is appropriate where a diaphragm-type flushometer is specified for a floor- or wall-mounted water closet in a commercial setting.

Compatibility

Designed as an OEM-style Regal series flushometer for commercial water closet applications requiring a 1.6 GPF diaphragm flush valve. Verify rough-in dimensions, supply stop size, and spud connection specifications against the installation drawing before ordering.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve line pressure before removing any existing valve or making connections. Do not overtighten the packing nut or spud coupling, as this can damage the valve body or the fixture spud. Inspect the diaphragm and relief valve seat during installation and replace any worn components before returning the system to service.
