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.

bit more and that fixed the problem next I used one of these snapped them apart and installed them on the hoses just to cover the big holes and give it a nice finished look I then took the knob apart by unscrewing this little piece then pulling out the cap remove the cover and unscrew the last cover this way I only have this brass piece left that I can actually use a wrench and tighten it nice and snug next I disassembled the faucet and made sure to have a bowl nearby as it will have water after your leak test I then place the faucet into Ziploc bag so that the greased up O-rings can be kept nice and clean I stuck a little piece of paper towel to prevent from more leaks and so that the pipe can stay clean next I took some measurements to know exactly where the knobs and the faucets are so that I can transfer them into the drywall and make some more holes I used my hole saw again that I have as part of the set and drilled out the three holes this last hole didn't cut all the way through so I had to use the blade to cut off the paper on the drywall I then used the sharp blade on my utility knife and cleaned up all the corners on the drywall so that it's easy to install the drywall without any problems it's also a good idea to Mark the center of the studs so you know where to screw in the drywall I then installed the board with two drywall screws I made sure to tape the knobs with some blue tape before beginning the messy part of the drywall
