Technician arrived to gather measurements on existing sink. Decided to give installation of the pop up a go. Was able to remove existing pop up assembly and installed new. Existing p-trap for sink was cross threaded so technician had to replace p-trap and trap adapter with new. Gathered information pertaining to the master bath tub and found that the faucet is a jacuzzi brand faucet. Will reachout to manufacturer on replacement cartridges.
