Often the hardest part of replacing a faucet is removing the old one. To get at it, you'll need to clear the cabinet jungle and you may need to remove the drain for access. Plan to replace supply lines. Replace defective valves or add shutoff valves if you don't have them. The basin wrench (Step 3) is a must-have tool for getting the job done right.
New faucets are surprisingly installer-friendly. Manufacturers provide good instructions, custom tools and easy-to-use fittings. If you install a faucet with a pull-out sprayer spout (like the one shown), you'll use only three of the four holes in the sink's rim. Cover the extra hole with a blank plate or use it for a soap or filtered-water dispenser. When selecting a faucet, look for solid-brass bodies with durable plating and washerless controls for longevity.
1. Disconnect drain lines and P-trap if they block your access
to the faucet and supply lines. Plug main drain with a rag to block sewer
gases. Use a towel on the bottom cabinet edge as a back cushion.
2. Shut off water supply and open faucet. When possible, open a lower faucet to drain the lines. If replacing or installing shutoff valves, turn off water main and cut pipe below old supply connections.
3. Reach behind sink to fit basin wrench around the locking nuts that hold the old faucet. Disconnect spray-nozzle hose and remove sprayer hose and faucet. (continue ...)

4. Follow manufacturer's preassembly instructions and hand-tighten flange nuts. Check alignment of flange, faucet and sink hole from above.
5. Slip on faucet washer and face-mounting nut. Gently spread supply tubes to make room for the tool and test whether sprayer hose fits through the opening. Tighten the nuts.
6. Thread
sprayer hose through faucet body and attach it. Attach counterweight and test that hose moves freely. Attach shutoff valves and supply lines.
Tip on making it easy:
If you're replacing the kitchen sink along with a new faucet, install the faucet and strainer baskets before setting the sink into the countertop. You'll save yourself a lot of reaching, straining and frustration.
