Using an adjustable wrench, loosen and unscrew the nuts connecting the hot and cold water supply lines from the shut-off valves. Next, locate the mounting hardware holding the old faucet in place under the sink. Use a socket wrench or basin wrench to loosen and remove the nuts securing the faucet.

Goal: Detach the old faucet from the sink and plumbing.

FAQs

How challenging is replacing a deck-mount garden tub faucet for someone with limited plumbing experience, and why does it take up to 6 hours?

This project is rated intermediate primarily due to the often tight and awkward access under the tub deck, and the potential for seized or corroded plumbing components. The 6-hour estimate accounts for troubleshooting, the slow process of working in confined spaces, and thorough leak testing to ensure a secure installation.

Why are multiple types of wrenches listed, especially two basin wrenches, and are they all essential for this project?

Multiple wrenches, including two basin wrenches (telescoping and standard), are highly recommended. This ensures you have the correct tool to reach and properly grip various nut sizes and angles, especially the difficult-to-access mounting nuts under the tub deck. Having both types of basin wrenches can be crucial for different space constraints.

What are the most critical steps to prevent leaks and potential water damage during and after this faucet replacement?

The most critical steps include completely shutting off the main water supply before starting and confirming no water is flowing. When installing, use Teflon tape on all threaded pipe connections (not on compression fittings unless specified) and tighten all nuts firmly but without overtightening. After installation, test for leaks thoroughly over several hours, checking all connections for drips.

What should I do if the old faucet nuts or supply lines are seized and won't loosen, or if I encounter heavy corrosion?

If parts are seized, apply penetrating oil like KROIL generously and let it sit for at least 15-30 minutes to work. Use firm, steady pressure with your basin wrench or adjustable wrench. If components are severely corroded or refuse to budge, you may need to carefully cut them away using a hacksaw, taking extreme caution to avoid damaging the tub or surrounding plumbing.

just going to leave that at that self explanatory. Next thing is disconnect the tap from your mines. You can see a few drips here, which is why I've got this little cloth here. So there we go. There we go. There's a bit of water drop it out, completely expected, which you'll have at a cloth down. This price mister has these great little quick disconnects. So I'm just going to turn, I'll show you this first because this is what you can see a little better. There we go, loosen it up. And don't just loosen up, take it off, it needs to come right off. There is this little guy here I need to get rid of too. All right, let's try this little 10 mail. Ooh, a little too small. And then 11 mail is too large. So I'm going to go to a non metric socket. There we go. Let's see if this works. There we go, boys and girls. Now, it's a great idea to not destroy this because I'm going to give this to have a tap for humanity because nothing wrong with this faucet. It's just not the style I want anymore. So let's pull that little retaining bracket off to squeeze these together. There is. And it's off and I'll put it all back together and give it to have a tap. And it'll
