Gerber 21-302 Pressure-assisted Round Toilet 1.6 Gpf

Product Description

The GERBER 21-302 is a pressure-assisted toilet designed for residential and light commercial plumbing installations. It features a round front bowl at standard height and uses a pressure vessel flush valve to deliver a forceful 1.6 gallons per flush (gpf). Pressure-assisted flushing relies on compressed air trapped inside a sealed vessel to drive water through the bowl at higher velocity than a standard gravity-feed unit, resulting in a more complete bowl clearing on each flush. Licensed plumbers and experienced DIYers install this fixture as a rough-in replacement or new construction unit.

This toilet is configured for a 12 inch rough-in, meaning the distance from the finished wall to the center of the closet flange measures 12 inches. This is the most common rough-in dimension in North American residential construction, making the 21-302 a practical fit for standard bathroom layouts. The round front bowl profile suits smaller bathrooms where space is at a premium. The standard bowl height is compatible with conventional toilet seat sizing.

Key Features

• Pressure-assisted flushing using a sealed pressure vessel for high-velocity bowl clearing

Compatibility

Designed as an OEM-style replacement or new installation toilet for standard 12 inch rough-in closet flange configurations in residential and light commercial plumbing systems.

Installation Notes

Installation must be performed in accordance with local plumbing codes and the International Plumbing Code (IPC) where adopted. Shut off the water supply at the stop valve and flush the existing toilet to empty the tank before removing any components. A licensed plumber should verify closet flange condition, wax ring selection, and proper supply line connection before setting the fixture. Pressure-assisted units require adequate supply line pressure to function correctly — consult the manufacturer documentation for minimum supply pressure requirements before rough-in.
