Mansfield Mansfield 3106 Toilet Tank Cover 1.28 Gpf

Product Description

The MANSFIELD mansfield 3106 is a replacement toilet tank and cover assembly designed for the Barrett toilet model. Built from vitreous china in a standard white finish, this tank delivers a 1.28-gallon-per-flush (GPF) performance, meeting WaterSense efficiency thresholds common in residential and light commercial applications. The integrated 3-inch flush valve supports a strong, complete flush cycle. At 19 inches wide and 8.75 inches deep, it fits the proportions of the Barrett bowl platform. This assembly is installed by licensed plumbers during toilet repair, renovation, or fixture replacement work.

This tank and cover assembly is suited for residential bathroom installations requiring a 12-inch rough-in measurement. The 12-inch rough-in is the most common toilet rough-in dimension in North American construction, making this tank a practical fit for standard residential bathroom layouts. It is used when the original Barrett tank is cracked, damaged, or missing, and a direct OEM-style replacement is needed without swapping the bowl.

Key Features

• 1.28 GPF flush volume meets current low-consumption plumbing standards
• 3-inch flush valve opening supports high-volume flush performance
• 12-inch rough-in compatibility aligns with standard North American bathroom framing
• Vitreous china construction provides a non-porous, stain-resistant surface

Compatibility

Designed as an OEM-style replacement tank and cover for the MANSFIELD Barrett toilet series with a 12-inch rough-in configuration.

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 at the stop valve and flush the existing tank fully before removal. Inspect the tank-to-bowl gasket and bolts and replace them if worn or damaged during the swap. Do not overtighten tank bolts, as vitreous china can crack under excessive torque.
