In this video

After the supply lines are detached, the mounting nuts holding the faucet are exposed. The presenter demonstrates how to use the basin wrench: position its head straight up to reach the nut, then slide the jaw over the nut. The spring-loaded jaw clamps onto the nut when you apply turning force to the handle. This allows you to grip the nut securely and turn the handle to break it loose, enabling the removal of the faucet.

Goal: Remove faucet mounting nuts.

FAQs

Why do I need a basin wrench specifically for this project, and can I use a different wrench instead?

A basin wrench's swiveling head and long shaft are uniquely designed to reach and grip faucet mounting nuts in the confined space behind a sink basin. Standard wrenches, like adjustable or pipe wrenches, are usually too bulky or lack the necessary angle and reach, making the job nearly impossible. Using the correct tool prevents frustration and potential damage to components.

What are the most important safety precautions when working in a tight space under a sink with a basin wrench?

Always wear safety glasses to protect your eyes from debris or drips. Ensure the area is well-lit (a headlamp like the Husky PVL-HLP-0004 is ideal) to clearly see the nuts and avoid injuries. Crucially, turn off the water supply to the faucet before starting to prevent unexpected leaks or sprays.

How long does it typically take for a beginner to successfully use a basin wrench, especially if nuts are corroded?

For a beginner, expect 30 minutes to an hour for removal and installation under typical conditions. If nuts are severely corroded or the space is exceptionally tight, it could take longer, potentially requiring repeated application of penetrating oil. Patience is key to avoid stripping the nuts and ensure a successful outcome.

What should I do if the faucet nuts are severely corroded and won't budge with the basin wrench?

Apply a generous amount of penetrating oil like KROIL and let it soak for at least 15-30 minutes, or even longer for stubborn nuts. Reapply and try again, using short, firm, counter-clockwise turns. For very stuck nuts, gently tap the wrench or nut (if accessible) to help break the corrosion bond after applying oil.

wrench. Once you remove the supply lines the nuts that are actually holding the faucet on the bottom of the sink they'll be exposed then you'll be able to get up in there and loosen those so you can remove the faucet and that's where you're going to use the basin wrench. It swivels right here so you can actually use it like a regular wrench but it also swivels right here too so you can like push it straight up back behind the sink and this you could just like a regular wrench it's just going to clamp onto the nut and once you've got it clamped on to your nut it springs into place. It gives it tension when you're turning it it clamps shut so you can actually just grab a hole in the nut and you can break it loose. That's the most often reason that you're going to need
