90/217 REPLACEMENT FLUSH VALVE ABSTRACT OF THE DISCLOSURE An assembly is provided for replacing part or all of a toilet flush valve, which facilitates mounting in a variety of toilets and which enables saving of water. The assembly includes an adapter (30, Fig. 6) for mounting on older types of overflow tubes, which includes a ring member (70) having a gap (72) and a leaf spring (80) extending across the gap. After the adapter is moved down along the overflow tube and lies at its base, the spring is pushed in to cause a hook (84) at one end to ride along a ramp (90) from a second tooth (88) to a third tooth (92) and engage the third tooth, to tightly clamp the ring member in place to prevent turning. A closing delay cup (116, Fig. 9) that can be used on a valve member, includes a plurality of holes and at least one plug (126) that is molded to the cup and can be cut off and used to plug one of the holes (120) to adjust the amount of water saved in each flushing. A valve member includes a tank ball having an enlargement (160, Fig. 12) at its top which is received in a yoke, in a universal joint that allow for limited pivoting of the tank ball to seal against valve seats of varying height and tilt.
