Correct Installation

**NOTE: The gray bearing washer has a small gap. The spout will nearly bottom out at the base plate of the faucet. You will notice that just a small portion of the washer will be showing once the spout has been reinstalled over the valve body.

  1. K9Installation1.pngLoosen the faucet from underneath the sink by using a 5/8” socket wrench or the installation tool on the mounting nut.
  2. Then, with one hand lift up the valve body.
  3. As the photo to the right shows you will want to place the bearing washer below the bottom O-ring into the groove and use both hands to squeeze the bearing washer into place.

  4. K9Installation3.pngOnce the bearing washer is set into position re-tighten the faucet mounting nut with your 5/8” socket wrench or installation tool.


INCORRECT INSTALLATION: The gray bearing washer in this photo has a much larger gap than the correct installation shows.
