In this video

The first practical demonstration takes place under a kitchen sink. The presenter identifies the plastic mounting nuts that secure the faucet to the sink. He positions the basin wrench head around one of the nuts. He sets the wrench to tighten and shows how to turn the handle to secure the faucet. It is noted that while the basin wrench works, the socket-style tool is often better for these types of plastic nuts because it engages the ears more securely without risk of slipping or damage.

Goal: Secure faucet to sink

  • Be careful not to over-tighten or apply uneven pressure to plastic nuts, as they can break.

FAQs

Do I really need a basin wrench for this project, or can I just use an adjustable wrench?

While an adjustable wrench can sometimes work for easily accessible nuts, a basin wrench (like the Husky Basin Wrench 16PL0127 mentioned) is highly recommended. It's specifically designed to reach and loosen mounting nuts in tight, awkward spaces under the sink, making the removal of the old faucet much easier and less frustrating, especially for beginners.

What's the most crucial step to prevent water damage during the faucet replacement?

Absolutely ensure both the hot and cold water supply lines are completely turned off at the angle stops beneath the sink before you begin any work. Test by briefly turning on the old faucet to confirm the water flow has stopped. Keep the Unger 6 Gal. Heavy-Duty Plastic Bucket ready to catch any residual water when disconnecting lines.

What should I do if the old faucet's mounting nuts are rusted or impossible to loosen?

For stubborn or rusted nuts, first try applying a penetrating oil like WD-40 or Liquid Wrench and let it sit for 10-15 minutes to help loosen them. If they still won't budge, you may need to carefully use a hacksaw blade or a rotary tool with a cut-off wheel to cut through the nuts, taking extreme caution not to damage the sink or supply lines.

The project lists the difficulty as 'beginner', but an estimated 3 hours seems long. What makes it take that much time?

The 'beginner' difficulty refers to the straightforward nature of the tasks, not necessarily the speed. The 3-hour estimate accounts for potential real-world challenges such as tight working spaces, rusted nuts, properly reading new faucet instructions, and thorough leak testing. Rushing can lead to mistakes, so taking your time to be meticulous is key.

Ouch! Okay, let's go underneath our sink and I'll show you some examples of how to use it. Okay, so these plastic fittings up here, there's one on each side. This actually clamps the faucet down and then here's our water supply lines. The basin range can be used on both of them. And we'll do the same thing to this right side. Now the socket style one's actually better for this kind of plastic fitting because it locks onto those ears. Doesn't damage them or anything. If you want to be careful not to break those ears.
