How to Replace a Deck-Mount Garden Tub Faucet · Step 8 of 9

Slowly turn the water back on at the shut-off valve by rotating the handle a quarter turn until it stops. You will hear the toilet tank begin to fill. As it fills, carefully inspect both connection points for any signs of water drips. Use a towel to thoroughly dry the fittings, valve, and the floor area around them. For a more reliable leak check, place a dry piece of toilet paper on the floor directly under the connections. Any small drip will quickly become visible on the paper. It is a good practice to check again after 20-30 minutes to ensure there are no slow, persistent leaks.
Goal: Verify the new installation is leak-free
- Toilet paper is very absorbent and will show even the smallest drop of water, making it an excellent tool for detecting slow leaks.

- Towel (Material: Fabric, Availability: Commonly found in households) — Drying the work area for an accurate leak check.

FAQs
Why is a specialized basin wrench necessary for this project, and can I complete it without one?
A basin wrench, like the Husky Basin Wrench 16PL0127, is crucial for reaching and loosening the mounting nuts of a deck-mount faucet from underneath the tub deck, especially in tight, awkward spaces. While some might attempt with long-handled pliers, a basin wrench makes the job significantly easier, prevents stripped nuts, and greatly reduces frustration. Attempting without it can significantly increase the difficulty and time spent on the project.
What are the most common reasons for leaks after installing a new faucet, and how can I prevent them?
Leaks often occur due to improperly tightened connections, missing or improperly seated O-rings/gaskets, or insufficient use of Teflon tape on threaded connections. To prevent this, ensure all supply line connections are hand-tightened first, then snugged with an adjustable wrench. Always apply Teflon tape clockwise to all threaded pipe connections and double-check all washer and gasket placements during installation and before leak testing.
The project is rated 'intermediate' and estimated at 6 hours. What makes it so time-consuming, and how can I potentially speed up the process?
The 'intermediate' rating and 6-hour estimate account for potential challenges such as corroded old fasteners, limited access under the tub deck, and the careful process of thorough leak testing. You can speed it up by having all tools and materials, including penetrating oil like KROIL, readily accessible and by applying the penetrating oil to old fasteners well in advance. Good lighting from a headlamp like the Coast HL40 also saves time by improving visibility in tight spaces.
Is it truly necessary to shut off the main water supply to the house, or can I just turn off the hot and cold valves under a nearby sink?
For a garden tub faucet replacement, you must shut off the main water supply to your house. Unlike sink faucets that often have dedicated shut-off valves, garden tubs typically do not have individual shut-off valves for their supply lines beneath the tub deck. This ensures no water flows during the disconnection process and prevents potential flooding.
