Patent ID: 7793679

Claim:
A method for assembling a drain valve, the method comprising: (a) providing a pipe that includes first and second opposite ends, a pipe bore extending from the first end to the second end, and a transverse hole extending through a side of the pipe and communicating with the pipe bore; (b) providing a valve assembly comprising a body having a body bore, and a rotatable mechanism within the body and having a mechanism bore and means for rotating the rotatable mechanism, the rotatable mechanism being rotatable via the means for rotating within the body to selectively align and misalign the mechanism bore with respect to the body bore; (c) inserting the valve assembly into the pipe bore with the means for rotating being accessible through the transverse hole; and (d) forming a first reduced diameter portion in the pipe bore to create a substantially water-tight seal between a portion of the valve assembly and the first reduced diameter portion; and (e) forming a second reduced diameter portion to provide a thrust bearing surface to resist sliding movement of the valve assembly toward the second end of the pipe; wherein step (e) is performed prior to step (c); and wherein step (c) includes abutting the valve assembly against the second reduced diameter portion in the pipe bore prior to step (d).
