Described is a wrench comprising a base plate having a generally circular periphery. A plurality of teeth extend radially from the periphery of the base plate and are adapted to engage the indentations in the top of a compression ring of a base assembly. The base plate has a shaft extending upwardly therefrom. Preferably, the shaft includes a handle portion which an installer may use to apply torque to the tool and, thereby, to the compression ring. The shaft may, however, be adapted for engagement with another tool, such as a pipe wrench or electric drill.

[ We claim:] [1.]1. In combination:a drain compression ring for use with a drain assembly that includes an internally threaded drain base and a deformable collar, said drain compression ring comprising an externally threaded ring having a lower end, and an upper end having a plurality of indentations formed therein;said lower end of said ring being adapted to contact and compress the deformable collar;and a compression ring wrench for use with said drain compression ring;said compression ring wrench comprising a base plate having a periphery and a plurality of spaced-apart teeth provided on said periphery, said plurality of spaced-apart teeth adapted to engage the indentations of the drain compression ring; and a shaft mounted on said base plate and extending upwardly therefrom;whereby said compression ring wrench may be engaged with said compression ring and rotated to install said compression ring within the internally threaded drain base and to compress the deformable collar.
