How to Install a Touchless Kitchen Faucet

In this video, This Old House plumbing and heating expert Richard Trethewey helps a homeowner install a new, no-touch kitchen faucet.

Steps:
1. Close the hot- and cold-water shutoff valves underneath the sink.
2. Use a basin wrench to disconnect both water-supply lines from the underside of the sink.
3. Twist off the hand sprayer from the spray hose, then pry off the retainer clip with a narrow screwdriver or a pocketknife.
4. Pull the sprayer base off of the spray hose, then push the hose down through the sink deck and into the cabinet below.
5. Drain the water from the spray hose into a bucket.
6. Pull out and discard the old faucet.
7. Place the new faucet’s mounting plate and gasket onto the sink deck.
8. Set the faucet in place by feeding its hoses and data cable down through the hole in the mounting plate.
9. From below, slide the ends of the hoses and cable through the support bar and mounting washer.
10. Thread on the hex nut and tighten with the supplied wrench to lock the faucet to the sink.
11. Feed the soap dispenser through the old hand-sprayer hole in the sink deck, then tighten the mounting nut from below.
12. Push the retractable spray hose into the gooseneck faucet and down into the cabinet.
13. Fasten the battery-powered control box to the inside of the cabinet with two screws.
14. Plug the water-supply lines, power line, and data cable into the push-to-connect fittings along the top and bottom of the control box.
15. Install the control-box battery, then adjust the water-temperature setting.
16. Snap the counterbalance weight onto the hose that’s connected to the retractable faucet spray head.
17. Open the shutoff valves, then test the faucet.
