Before you begin, safety first! Locate the hot and cold water supply valves under your sink. Turn them clockwise to completely shut off the water supply. Turn on the faucet briefly to release any remaining water pressure in the lines. Place a bucket or absorbent towel beneath the sink to catch any drips.

Using an adjustable wrench and, if necessary, a basin wrench (for hard-to-reach nuts), carefully disconnect the water supply lines from the old faucet. Then, remove the mounting nuts securing the faucet to the sink. Take photos as you proceed to assist with reassembly.

Clean the sink surface thoroughly. Carefully follow the manufacturer's instructions for installing your new faucet. This will typically involve connecting the water supply lines (ensuring a tight seal), installing the faucet body, and securing it with the mounting hardware. Once installed, slowly turn the water supply back on and check all connections for leaks.
