How to Replace a Two-Handle Bathroom Faucet · Step 7 of 10
In this video
From underneath the sink, assemble the mounting hardware onto the faucet shank. The correct order is typically the rubber washer first, then the brass washer, and finally the locking clamp. Hand-tighten the locking clamp to hold the faucet in place. Check the faucet's alignment from above, then use pliers to give the clamp a final quarter-turn. Finish by tightening the two set screws on the locking clamp with a screwdriver to fully secure the faucet.
Goal: Mount the faucet securely to the countertop.
- Before assembling, back the set screws out on the locking clamp to make it easier to install.
- If it's difficult to pass all hoses through the locking clamp, you may need to pull the sprayer hose out from the top temporarily.

FAQs
How long should a beginner expect to spend replacing a two-handle bathroom faucet and drain?
For a beginner, this project typically takes 2-4 hours, assuming no major complications like seized nuts. The difficulty is rated as 'beginner' because it involves straightforward steps, but patience is key, especially when working in tight under-sink spaces.
Are there any essential tools I might not already have that are crucial for this faucet replacement?
Yes, a basin wrench (like the Husky 1-1/2 in. Quick-Release Telescoping Basin Wrench) is invaluable for reaching and loosening nuts in tight spaces under the sink. You'll also want a quality adjustable wrench, tongue and groove pliers (Channellock 442), and a reliable flashlight (Panther Vision FLATEYE F-310) for visibility.
What are the critical preparation steps and safety precautions before I start disconnecting anything?
Always begin by shutting off both the hot and cold water supply valves under the sink, then turn on the old faucet to relieve pressure and drain residual water. Have a bucket (Unger 6 Gal. Heavy-Duty Plastic Bucket) and a rag (Better Trends Hugo Collection Bath Rug) ready to catch any spills and protect your cabinetry.
What are the most common reasons for leaks after installing a new faucet or drain, and how can I prevent them?
Leaks often occur from loose supply line connections or improper sealing of the drain assembly. Ensure all connections are hand-tightened, then given an additional quarter to half turn with a wrench. For the drain, properly apply plumber's putty (Oatey 14 oz. Plumber's Putty) around the flange before seating it.
