In this video

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

Why is a basin wrench specifically recommended for this project, and are there alternatives?

A basin wrench is essential because its long shaft and swiveling jaw allow you to reach and loosen nuts in cramped spaces under the sink, particularly those securing the faucet. While other wrenches might fit some nuts, a basin wrench is designed for the tight angles and often inaccessible positions encountered when working on faucets.

What are the common issues to watch for when reconnecting the water supply lines to avoid new leaks?

A common mistake is not tightening the connections enough, leading to slow drips, or over-tightening, which can strip threads or damage washers. Ensure the supply lines are hand-tightened, then use a wrench for a quarter to a half turn more. Always check for leaks immediately after turning the water back on and tighten slightly if needed.

What safety precautions should I take beyond just turning off the water supply?

In addition to shutting off the water, place the Unger 6 Gal. Heavy-Duty Plastic Bucket DB02 directly under your workspace to catch any residual water. Wear safety glasses to protect from drips or debris, and consider gloves for a better grip and to protect your hands from grime under the sink, especially in tight, dirty spaces.

My faucet is dripping from the spout, but this guide focuses on supply lines. Will this project fix that type of drip?

This specific guide primarily addresses leaks originating from the water supply lines or their connections to the faucet tailpieces. If your faucet is dripping from the spout itself, the issue is likely with internal components like worn-out O-rings, cartridges, or washers, which would require disassembling the faucet's body, not just inspecting the supply lines.
