Angle the nozzle on the jet you wish to remove so that it points upwards.
Insert the bathtub jet removal tool into the opening on the jet.
Press the removal tool towards the top of the jet until it stops and pull slightly back so the hook at the end of the tool catches on the back of the nozzle.
Pull firmly backwards on the jet removal tool until the jet slides out of the side of the bathtub.
Pry the whirlpool jet out of the side of the tub with alternative methods if you do not have the removal tool. One way to do this is by inserting metal washers in between the edge of the jet and the tub to pry the jet slowly out of the tub plumbing.
