Begin by turning off the water supply and draining the pipes to prevent spills. Remove the old faucet by unscrewing the mounting nuts and carefully lifting it out. Clean the sink receptacle thoroughly, then install the new faucet by aligning it with the mounting plate and securing it with nuts—ensuring a snug, leak-resistant fit. Reconnect supply lines securely and restore water flow to test for drips before finalizing installation.

If your sink drain is clogged or corroded, replacement offers lasting improvement. Start by removing the old drain assembly, including the P-trap and trap arm. Inspect the drain pipe for damage and clean debris thoroughly. Install a new drain with a corrosion-resistant material like ABS or PVC, ensuring a tight seal to prevent future leaks. Reconnect the supply lines and verify proper drainage by running water and checking for slow flow or pooling.

Always turn off water before starting, use plumber’s tape on threaded connections, and handle seals gently to avoid cracking. If unsure, consult a licensed plumber to ensure code compliance and long-term reliability. A well-executed replacement enhances both performance and bathroom aesthetics.
