After shutting off the water, disconnect the flexible supply lines that run from the shut-off valves up to the faucet connections under the sink. Use an adjustable wrench to loosen the nuts connecting the lines. Be prepared for a small amount of water to drip out from the lines. Have a bucket and a cloth or towel ready to catch this residual water.

Goal: Disconnect Water Supply Lines

  • Water will drip from the disconnected lines, even with the valves closed.
  • Place a small bucket or a towel directly under the connections to keep the floor dry.

FAQs

What specialized tools are essential for replacing a kitchen faucet, especially for a beginner?

A basin wrench (like the TEKTON or Husky models listed) is crucial for reaching and loosening nuts in tight spaces under the sink. An adjustable wrench is also a must-have for supply lines. A sturdy bucket will catch drips and keep your workspace clean.

What's the most critical safety step before I start, and what should I do if old connections are corroded and won't loosen?

Always turn off the water supply to the sink, either at the shut-off valves under the sink or the main house valve. If connections are stuck, apply penetrating oil, let it sit, and use a basin wrench with steady pressure. Avoid excessive force to prevent stripping or damaging pipes.

The project estimates 4 hours, but I'm a complete beginner. Is this realistic, and what could make it take longer?

For a complete beginner, it's wise to budget 6-8 hours. Old, corroded parts, extremely tight working spaces, or unexpected plumbing issues can significantly extend the installation time. Don't rush; taking your time prevents costly mistakes.

After installing the new faucet, I'm noticing drips or leaks. What are the most common culprits I should check?

First, ensure all water supply lines are securely tightened to the faucet and the shut-off valves, but don't overtighten plastic nuts. Next, check if the mounting nuts under the sink are snug and that the faucet's base gasket is properly seated and compressed against the sink surface, preventing leaks from above.
