Abstract
Abstract A flush valve is connectable to a vertical wall of a toilet tank. An overflow tubular member is in fluid communication with the flush valve housing and there are clip members mounted on the overflow member for connection with a flapper valve. In a preferred manner, the clip members are mounted on the back side of the overflow member whereby the overflow member acts as a guide, as well as a stop for the flapper valve.

Claim 1
Independent Claim
156 words
A flush valve attachment system for connecting a flush valve to an essentially vertical wall of a toilet tank the tank having an outlet formed in said wall, the system comprising: a flush valve having a housing adapted to extend through the outlet with a projection extending radially outwardly from the housing on the exterior side of the wall; said housing being rotatable between a first position in which the projection can pass through the outlet, and a second position where the projection can catch on the exterior side of the wall; an overflow tubular member in fluid communication with the housing of the flush valve, the overflow member including at least two vertically spaced clip members; said housing having a channel therethrough extending between the overflow member and the outlet; and a flapper valve connected to at least one of the clip members, the flapper valve being constructed and arranged to seat over the channel.
