Install New Faucet & Secure Base

What happens here

If your sink has multiple faucet holes but the new faucet is a single-hole design, place the provided mounting plate (escutcheon) over the holes on the countertop. Carefully insert the new faucet assembly, including its pre-attached supply lines and sprayer hose, through the center hole in the countertop. From underneath the sink, align the large mounting nut onto the threaded shaft of the faucet. Have a second person firmly hold the faucet in the desired position from above the sink, ensuring it is straight and centered. Begin hand-tightening the mounting nut from below. Once hand-tight, use a basin wrench or the manufacturer's provided tool to give it a final snug turn, securing the faucet firmly in place without overtightening.

Goal: Place the new faucet onto the countertop and securely tighten it from underneath the sink.
