Universal flush valve kit and method of using

摘要

An adapter cup for use in a multi-piece valve assembly, a universal flush valve assembly kit and a method of installing in a flush tank with a discharge hole. The kit has a first adapter cup, an additional adapter cup and a main body valve fitting. The adapter cups have substantially identical upper rims that are configured for attachment to the main body valve fitting. Each adapter cup has a lower cylindrical portion with a different outer diameter than that of the other adapter cup. The lower portion of one of the adapter cups is inserted into a discharge hole of like or substantially similar diameter. The main body fitting with an inlet and outlet is attached to the rim of the inserted adapter cup. A flapper is swingable relative to the main body fitting from a closed position abutting the outlet to an open position raised from the inlet. A single flush tank valve assembly can be installed into toilet tanks with different sized discharge holes.
