Follow these steps carefully to ensure a smooth replacement.

Step 1: Turn Off the Water Supply

• Locate the hot and cold shutoff valves under the sink

Never skip this step when learning how to replace a kitchen faucet with two handles.

Step 2: Disconnect the Water Supply Lines

Label hot and cold lines if needed to avoid confusion later.

Step 3: Remove the Old Faucet and Handles

Some older faucets may require penetrating oil if nuts are stuck.

A clean surface ensures proper sealing and prevents leaks.

Step 5: Install the New Faucet and Handles

Make sure everything is aligned before tightening.

Step 6: Connect the Water Supply Lines

• Attach hot and cold supply lines to the correct valves
• Hand-tighten first, then gently tighten with a wrench
• Do not overtighten

Overtightening is a common mistake when replacing faucets.

Step 7: Test for Leaks and Proper Operation

• Slowly turn the water supply back on
• Check all connections for leaks
• Turn handles on and off to test flow

If leaks appear, tighten slightly and test again.

Avoid these frequent mistakes:

• Forgetting to turn off the water supply

These mistakes cause most post-installation problems.
