Toilet valve assembly

A dual flush volume outflow valve assembly for a toilet tank, the outflow valve assembly comprising:

• a base configured to be coupled to the toilet tank, the base including an opening for passing water out of the toilet tank;
• a lower outflow tube section extending upwardly from the base, the lower outflow tube section having a side and a hollow interior;
• a high-volume flush valve disposed on the side of the lower outflow tube section, the high-volume flush valve being positioned to discharge a first, larger volume of water from the toilet tank when opened;
• an upper outflow tube section adjustably coupled to the lower outflow tube section, the upper outflow tube section having a hollow interior and including a low-volume flush valve positioned to discharge a second, smaller volume of water when opened, wherein the hollow interior of the upper outflow tube section and the hollow interior of the lower outflow tube section are positioned over and in line with the opening in the base, wherein the upper outflow tube section is coupled to the lower outflow tube section in a telescopically adjustable manner;
• and
• an overflow tube coupled to the side of upper outflow tube section, wherein the overflow tube includes a lower overflow tube section fixed to the upper outflow tube section and an upper overflow tube section adjustably coupled to the lower overflow tube section, and wherein the lower overflow tube section includes a lower portion that is spaced from the side of the upper outflow tube section and extends to a level below where the lower overflow tube section couples to the side of the upper outflow tube section.

• a lower outflow tube section extending upwardly from the base, the lower outflow tube section having a hollow interior and including a high-volume flush valve positioned to pass a first, larger volume of water from the toilet tank to the toilet bowl when opened;
• an upper outflow tube section coupled to and extending upwardly from the lower outflow tube section in a slidably adjustable manner, the upper outflow tube section having a hollow interior and including a low-volume flush valve positioned to pass a second, smaller volume of water from the toilet tank to the toilet bowl when opened, wherein the hollow interiors of the upper outflow tube section and the lower outflow tube section are positioned over and in line with the opening;
• and
• an overflow tube coupled to the side of upper outflow tube section, wherein the overflow tube includes a lower overflow tube section fixed to the upper outflow tube section and an upper overflow tube section adjustably coupled to the lower overflow tube section, and wherein the lower overflow tube section includes a lower portion that extends to a level below where the lower overflow tube section couples to the side of the upper outflow tube section.

A dual flush volume outflow valve assembly for a toilet tank, the outflow valve assembly comprising:

• a lower outflow tube section, the lower outflow tube section including a base configured to be coupled to the toilet tank, a generally upright tube section extending vertically upward from the base, wherein the upright tube section includes a hollow interior configured to pass water out of the toilet tank and to receive the insertion of an upper outflow valve section, and a side tube section extending horizontally away from the upright tube section parallel to the bottom of the toilet tank, wherein the side tube section terminates in a high-volume flush valve;
• and
• an upper outflow tube section slidably coupled to the lower outflow tube section, the upper outflow valve section including an elongate neck section having opposing ends, wherein one end of the elongate neck section is configured to be inserted into the upright tube section on the lower outflow valve section to slidably couple the upper outflow valve section to the lower outflow valve section, and wherein the other end of the elongate neck section terminates in a low-volume flush valve, the upper outflow tube section also including an overflow tube coupled to the upright tube section in a laterally displaced relationship to the elongate neck section, wherein the overflow tube includes an upper overflow tube section adjustably coupled to a lower overflow tube section, and wherein the lower overflow tube section extends to a level below where the overflow tube couples to the upright tube section.
