ABSTRACT:
A tool for pulling faucet handles and flow control cartridges from a faucet housing. A pair of spaced apart jaws are pivotally coupled with a block. A bolt extends centrally through the block and a chuck on the end of the bolt is used for coupling either a shaft or a claw. When pulling a handle the shaft is coupled with the bolt and the jaws are coupled with the handle. Extension of the bolt exerts an upward force which results in removal of the handle. The claw may then be inserted into the chuck and coupled with the cartridge. Retraction of the bolt then exerts an upward force which causes removal of the cartridge.
