Abstract
A single-piece flush valve assembly for increasing the flush rate out of a discharge hole in a tank. The kit has an upper portion with an upper cylindrical wall defining an upper bore and a lower portion with a lower cylindrical wall defining a lower bore. The lower bore is smaller than the upper bore. The upper portion defines an inlet and the lower portion defines an outlet. The upper and lower bores are fluidly connected and collectively define a discharge conduit that extends from the inlet to the outlet. The lower portion is inserted into a discharge hole of like or substantially similar diameter. A flapper is swingable relative to the valve assembly from a closed position abutting the inlet to an open position raised from the inlet. The upper bore of greater relative diameter to the lower bore increases the rate of flow out the discharge hole.
