As part of a larger kitchen renovation project, a homeowner wants to start with the simple replacement of the kitchen faucet with a new model that he has already purchased. The original faucet is a single tap and lever model. As part of the faucet retrofit, we install shut-off valves and then update with a single tap and individual water valves.

Turn off the hot and cold water supply to the kitchen faucet--we found the shutoff valves that controlled the first floor in the basement. Open the kitchen faucet to bleed off the water and any remaining water pressure.
Remove the sink drain, starting with the dish washer hose and PVC plastic plumbing to provide more room and easier access. Removal is simple and reinstallation will be, too.
Cut the copper water lines with a pipe cutter to detach the lines from the faucet. You will install new shutoff valves beneath the sink so the water supply can be shut off without disturbing the rest of the house.
Use a basin wrench to loosen cut water lines from the faucet and loosen the retaining nut that holds the faucet base. Lift out the old kitchen faucet and remove the old plumbers putty without scratching the stainless steel sink.
Install new shutoff valves on the incoming water lines below the sink. Slip the valves over the ends of the copper pipes and tighten the compression fitting with two wrenches to avoid spinning the fitting and twisting the pipe.
Place a rubber O-ring on the new kitchen faucet base and insert it into the precut hole in the sink. Secure the mounting plate beneath the sink and secure it with a retaining nut and the plastic socket provided.
Insert the spray nozzle hose into the end of the faucet, pushing it through and out the bottom. Push the hose all the way through and out the bottom side of the faucet base.
Apply plumbers putty to water valve bases. Insert the valves upwards through the sink, add C-rings, and hand-tighten the nuts beneath. Finish with the basin wrench. Clip on the hose that connects the valves to the faucets.
Connect the new water supply lines to the kitchen faucet and new shutoff valves. Screw the valve handles and trim on top of the valve bodies. Install the pump housing and pump for the liquid soap dispenser.
Replace the drain plumbing beneath the sink, including the P-trap assembly and the dish washer hose. Lay paper towels on the bottom of the cabinet to test for leaks before you turn on the water at the shutoff valves.
