Gerber av-21-862 Elongated Toilet Bowl 1.28/1.6 Gpf

Product Description

The GERBER av-21-862 is an elongated toilet bowl from the Avalanche series, designed for residential and light commercial bathroom installations. This bowl operates at a dual-flush rate of 1.28 gallons per flush (GPF) for liquid waste and 1.6 GPF for solid waste, meeting WaterSense efficiency thresholds without sacrificing performance. Finished in white, it pairs with compatible tank units to form a complete two-piece toilet system. Licensed plumbers and facilities maintenance technicians are the primary installers of this fixture.

The av-21-862 suits standard residential bathrooms as well as light commercial restroom applications where elongated bowl geometry is preferred for user comfort. The dual-flush mechanism supports water conservation goals in jurisdictions with low-flow plumbing requirements. This bowl is intended to be paired with a compatible Avalanche series tank to complete the toilet assembly. Rough-in dimensions and tank compatibility should be confirmed prior to installation.

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 flush the existing system to relieve pressure before removing any existing fixture. Use a wax ring or approved gasket seal at the floor flange, and confirm the rough-in measurement matches the installation location before setting the bowl. Do not overtighten floor bolts, as this can crack the porcelain base.
