  • Skill Level & Time to Complete
    • Beginner - 2 to 3 hours
    • Intermediate - 1 to 2 hours
    • Advanced - 1 hour
  • Caution: Always turn water supply OFF before removing existing faucet.

Steps

  1. 1

    Completely clean and dry the faucet mounting area.

  2. 2

    To install the optional sprayer hose, slide the foam gasket onto the hose guide shank and tuck the outer edge of the gasket under the hose guide. Install hose guide through the furthest left or right hole on the sink.

  3. 3

    From under the sink, thread extended locknut on shank of hose guide and tighten by hand. Feed the spray hose down through the hose guide but don't connect it to the faucet.

  4. 4

    When installing a Deck Plate model faucet, do not unbend supply tubes until after the tubes have been inserted through the sink hole. Install the faucet through the deck holes with the threaded shank to the back. Center the faucet on the sink with support plate oriented in the sink holes. Turn the spout sideways to keep the faucet from leaning forward.

  5. 5

    For Deck Ring models, do not unbend supply tubes until after the tubes have been inserted through the sink hole. Place deck ring over supply tubes and threaded shank against bottom of faucet body. Install faucet through deck hole with threaded shank to the back. Turn the spout sideways to keep the faucet from leaning forward.

  6. 6

    For deck holes up to 1 1/8" inch deep, install the mounting bracket open side up. Deck holes greater than 1 1/8" deep – install the open side down. For spray models, a groove on the threaded shanks indicates the minimum amount of exposed thread. For models without a spray, a minimum of ½" of threaded shank must be exposed. Position mounting bracket onto threaded shank and around supply tubes. Do not kink the tubing. Install mounting nut and tighten by hand.

  7. 7

    Making sure the faucet is positioned evenly, make final tightening with mounting tool.

  8. 8

    Carefully straighten each supply tube using two-hands. If using flexible supply lines with compression fittings, thread supply line nuts with fingers. Then while holding one nut with a wrench, tighten nut with another wrench. Rotating one-half turn. Do not over-tighten. Make connections to both hot and cold supply lines. The hot supply line is always on the left when threaded shank is in the rear.

  9. 8b

    Connecting your new Moen faucet to the existing flexible water supply lines will require using a wrench to snug up the connections. Some models will now include flexible supply lines. For these installations, remove the old flexible supply lines from the existing stop valves and attach the new lines directly to the valves. In either case, be careful not to over-tighten.

  10. 9

    If you have the optional sprayer and a Deck Plate model, feed the spray hose through the deck plate hole, and then connect spray hose swivel nut to the threaded shank. Tighten swivel nut by hand plus ¼ turn with pliers being careful not to twist the hose. Do not over-tighten.

  11. 10

    Connect spray hose swivel nut to the threaded shank. Tighten swivel nut by hand, plus ¼ turn with pliers being careful not to twist the hose. Do not over-tighten the nut.

  12. 10b

    Most Moen kitchen faucets now feature a Hydrolock connection to attach the side spray hose to the underside of the faucet. The white clips on the adapter need to be in the full open position. Slide the hose into the Hydrolock connector as far as possible then push in the white clip. There will be a distinctive "click" sound. Repeat the process when attaching the Hydrolock connector to the faucet. Be careful to join these fittings as straight as possible.

  13. 11

    To avoid damages to your new faucet, do not turn on supply valves until following these instructions. Remove the aerator and turn the faucet to the cold position. Turn on the cold supply for 15 seconds. Without shutting the faucet off, turn the faucet to the hot position and turn the hot supply on for 15 seconds. Next, turn the faucet to the mid position and turn on the spray for 15 seconds. Shut off the faucet, re-install the aerator and check the system for leaks. Your new Moen faucet is now ready for normal use.
