Step-by-Step Instructions
Turn off water supply
2-5 minutes
Find the hot and cold shut-off valves under the sink. Turn both clockwise to shut off. Open the faucet to release pressure and confirm water is off.
Disconnect the sprayer (if applicable)
5 minutes
If you have a separate sprayer, disconnect it from the faucet assembly. Some are threaded, others have a quick-connect fitting.
Disconnect supply lines
5-10 minutes
Place bucket under connections. Disconnect supply lines from the faucet using an adjustable wrench. Let remaining water drain into bucket.
Remove the old faucet
10-20 minutes
Use a basin wrench to reach up and remove the mounting nuts. Kitchen faucets often have a large center nut or two smaller nuts. Remove any mounting hardware and lift out the faucet.
Pro Tip
Kitchen faucets are often held with a single large mounting nut. A basin wrench makes this much easier.

5 minutes
Scrape away old caulk and putty. Clean the area around the mounting holes thoroughly.
Install the new faucet
15-20 minutes
Thread supply lines and any other components through the mounting holes from above. Apply sealant as directed by manufacturer. Tighten mounting hardware from below.
Pro Tip
Many modern kitchen faucets have a mounting bracket that makes installation easier. Follow your faucet's specific instructions.
Connect supply lines
10 minutes
Apply plumber's tape to threaded connections. Connect hot to hot (left) and cold to cold (right). If you have a sprayer hose, connect it according to manufacturer instructions.
Test for leaks
5-10 minutes
Turn on water slowly. Check all connections for leaks. Test the faucet and sprayer functionality. Check again after running water for several minutes.
Common Mistakes to Avoid
- Not having a basin wrench (makes the job much harder)
- Forgetting to connect the sprayer hose before mounting
- Over-tightening plastic fittings
- Not testing the sprayer function
Safety Warnings
- Turn off water before starting
- The space under a kitchen sink is cramped - work carefully
When to Call a Professional
If you find corroded pipes, water damage, or if the sprayer requires drilling a new hole in your sink or countertop.
