Step 3 · Remove the Sprayer Assembly
Now trace the sprayer hose up to the underside of the sink deck or countertop. You will find a large plastic or brass mounting nut threaded onto the sprayer's base, holding it in place. Using a pair of adjustable or channel-lock pliers, grip the nut and turn it counter-clockwise to loosen it. If it's hard to reach, a basin wrench may be necessary. Once the nut is completely unthreaded and removed, go to the top of the sink and pull the entire sprayer head and hose assembly up and out through the hole.
