A dual flush-volume outflow valve assembly for a toilet tank is provided. The outflow valve assembly comprises a base having an opening configured to pass water out of the toilet tank, a lower outflow tube section extending upwardly from the base, and an upper outflow tube section adjustably coupled to and extending upwardly from the lower outflow tube section. The lower outflow tube has a hollow interior and includes a high-volume flush valve positioned to pass a first, larger volume of water from the toilet tank to the toilet bowl when opened. The upper outflow tube section has a hollow interior and includes a low-volume flush valve positioned to pass a second, smaller volume of water from the toilet tank to the toilet bowl when opened. In some embodiments, the hollow interiors of the upper outflow tube section and the lower outflow tube section are positioned over and in line with the opening.
