A flush system for use in a toilet has a hollow body with an upper valve port and a lower valve port on which are seated an upper valve and a lower valve. The respective valves are attached to a first connecting rod and a second connecting rod. The connecting rods are attached to respective handles which are pivoted to unseat the respective valves. Unseating the upper valve produces a full flush of the toilet using a smaller regulated amount of water and unseating the lower valve produces a full flush of the toilet using a larger regulated amount of water. The handles are collocated on the outside of a water storage tank and the stems of the handles are coaxial. A bend is formed on the second connecting rod such that when the first handle is pivoted, the bend on the second connecting rod engages the first connecting rod and both the upper valve and the lower valve are unseated by the movement of the first handle. The bend portion of the second connecting rod may be broken-away to provide independent control of the unseating of the upper valve and lower valve by the respective second handle and first handle.
