Types of Kitchen Faucet Installations
Understanding your faucet installation type is critical before you begin.

Single-hole faucets are the most common option in modern kitchens. They install through one opening and often include a deck plate to cover unused holes.

> Three-Hole Kitchen Faucet Installation
Three-hole setups are common in traditional kitchens and support widespread faucets, bridge faucets, or side accessories.
> Wall-Mount Kitchen Faucet Installation
Wall-mount faucets install into the wall rather than the sink deck and require precise plumbing rough-ins.
What to Check Before Installing a Kitchen Faucet
- Sink hole count: Verify the number of mounting holes.
- Countertop thickness: Thick stone may require extended hardware.
- Rear clearance: Pull-down faucets need full spray-head movement.
- Faucet reach: Spout reach should align with sink bowl depth.

-
Shut Off Water and Remove the Old Faucet
Turn off both shutoff valves and open the faucet to relieve pressure. Disconnect supply lines and remove mounting hardware using a basin wrench if needed.
-
Prepare the Mounting Surface
Clean the sink deck thoroughly and remove old sealant. Dry-fit deck plates or escutcheons before final placement.
-
Install the New Faucet Body
Insert the faucet through the mounting hole and seat the gasket or sealant per manufacturer instructions. Align the faucet before tightening.
-
Secure the Mounting Hardware
Tighten mounting brackets evenly from below. Avoid overtightening, especially on stainless or thinner sink decks.
-
Connect Supply Lines and Sprayer Hose
Attach hot and cold supply lines. Install the pull-down hose and counterweight, ensuring free movement inside the cabinet.
-
Test for Leaks and Operation
Turn the water on slowly and inspect all connections. Test spray modes, handle movement, and hose retraction.
Installation Differences by Faucet Type
Pull-Down and Pull-Out Faucets
These require correct hose routing and counterweight placement for smooth retraction.
