Replace Your Kitchen Faucet: Step-by-Step Guide · Step 2 of 3
In this video
Using a basin wrench, attempt to loosen and remove the plastic mounting nuts that secure the old faucet to the underside of the countertop. If the nuts are stripped and cannot be removed, carefully use an oscillating multi-tool with a metal-cutting blade to cut through the plastic nut. Once cut, use pliers or a screwdriver to pry the pieces off. After the nuts are removed, lift the old faucet assembly off the sink.
Goal: Faucet Removal (Standard)
- Be extremely careful when using a cutting tool under the sink to avoid damaging the countertop, the sink itself, or the water supply lines.
- Standard basin wrenches may not fit all nuts. A larger, more robust model, like the Rigid one shown, may be necessary for better grip and leverage.

FAQs
What's the absolute first thing I should do before even touching my old faucet?
Always prioritize safety by turning off the hot and cold water supply valves located directly under your sink. Then, open the old faucet to drain any remaining water from the lines and relieve pressure, which helps prevent unexpected spills and makes disconnecting easier.
The project mentions an adjustable wrench and a basin wrench. Are these specialized tools, and do I really need both?
A basin wrench is highly recommended as it's specifically designed to reach and loosen the mounting nuts in tight spaces behind the sink, which a standard adjustable wrench often can't access. While an adjustable wrench handles most other connections, the basin wrench can be a lifesaver for tricky spots, especially for beginners working in confined areas.
What are the most common reasons for leaks after installing a new faucet, and how can I prevent them?
Leaks usually stem from improperly tightened connections or insufficient sealing. Ensure all supply line connections are snug but don't overtighten, and always use plumber's tape on threaded connections and plumber's putty or the manufacturer's gasket under the faucet base to create a watertight seal.
How long should this project realistically take for a beginner, and are there any tips to make it go smoother?
For a beginner, plan for 1-3 hours, but it could take longer if you encounter rusty nuts or tight spaces. A great tip is to take photos of the existing plumbing connections before disconnecting anything; this visual reference can be invaluable when connecting the new faucet's lines in the correct order.
