From under the sink, attach the hot and cold water supply lines to the corresponding faucet tailpieces (hot on the left, cold on the right). Hand-tighten the coupling nuts, then use your basin wrench or adjustable wrench to give them an additional quarter to half turn. Do not over-tighten. Connect the other end of the supply lines to the shutoff valves if you are replacing them. Connect the side sprayer hose to its designated port on the faucet body, often a quick-connect fitting.
You're viewing a step from: How to Replace a Two-Handle Kitchen Faucet
This project involves the complete removal of an old two-handle kitchen faucet and the full installation of a new one. The process begins with shutting off the water supply, disconnecting the old hardware, cleaning the sink deck, mounting the new faucet, connecting the new water lines, and finally, testing for leaks and proper operation.
Frequently Asked Questions
Do I really need a special basin wrench, or can I just use a regular adjustable wrench for this project?
While an adjustable wrench is useful for visible connections, a basin wrench (like the TEKTON or Husky models listed) is highly recommended. Its long, telescoping handle and pivoting jaw allow you to reach and loosen nuts in tight, awkward spaces under the sink that a standard wrench cannot access. This tool significantly simplifies the removal and installation process.
What are the most important safety precautions to take when replacing a kitchen faucet?
The most crucial step is to completely shut off the hot and cold water supply lines to your sink before starting any work. Ensure you have a bucket and towels handy to catch any residual water, and use proper lighting (like the listed flashlight) to see clearly in the confined under-sink area. Never try to force connections without proper alignment, as this can cause damage.
The project is rated "beginner." Is it truly manageable for someone with no plumbing experience?
Yes, this project is beginner-friendly because it primarily involves disconnecting and reconnecting parts, not complex pipe cutting or soldering. The most challenging aspect is often working in confined spaces under the sink. Take your time, follow the instructions carefully, and ensure all connections are hand-tightened before a final wrench turn to avoid cross-threading.
What should I do if I can't get the old faucet nuts or supply lines to loosen?
Old nuts can be stubborn due to corrosion or mineral buildup. First, try applying penetrating oil and letting it sit for a few minutes before using your basin wrench for leverage. If still stuck, a hacksaw or oscillating tool might be necessary to carefully cut the old nuts or lines, but proceed with extreme caution to avoid damaging the sink or existing plumbing.
