Return to the main water supply valve and turn it back on. Go back inside to the shower and turn on the hot and cold taps to test the new shower head. Carefully observe all connections for any signs of dripping or leaks. If you see a leak, turn the water off and tighten the connection slightly more or add more thread seal tape.

Goal: Test the new installation

  • If you see any drips, just tighten the shower head a bit more, or add more thread seal.

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.

Lastly, turn your water supply back on and give it a test run. Once your shower is running, check for leaks around the connection. If you see any drips, just tighten the shower head a bit more or add more thread seal.
