Disconnect Water Supply Line — Remove Old Faucet Mounting Hardware
Part of project
How to Replace a Deck-Mount Garden Tub Faucet · Step 4 of 9
In this video
Since the cartridge nut on top is seized and cannot be loosened with a socket wrench, the entire valve assembly must be removed from underneath the sink to get better leverage. Use wrenches to disconnect the rigid water supply pipe from both the shutoff valve and the bottom of the faucet valve assembly. Have a rag ready for residual water.
Goal: Remove supply line
- The nuts, especially on older plumbing, can be very tight. Use two wrenches, one to hold the valve steady and one to turn the nut, to avoid damaging the pipes.

FAQs
Is this project truly intermediate, and what are the main challenges I might face?
Yes, this project is rated intermediate due to the tight spaces often found under garden tubs, potential corrosion on old fasteners, and the critical need for watertight seals. Expect to spend significant time gaining access, maneuvering tools, and meticulously checking for leaks. Patience and preparation are key.
My old faucet seems stuck or corroded to the deck. What's the best way to loosen it?
Corrosion is common. Apply a penetrating oil like KROIL directly to the nuts under the tub deck and allow it to soak for at least 30 minutes, or even an hour. Use a basin wrench for extra leverage in tight spots, as it's designed for these hard-to-reach fittings.
What are the most common reasons for leaks after installing a new deck-mount faucet, and how can I prevent them?
Leaks typically occur from improperly sealed connections or loose fittings. Always apply 2-3 wraps of Teflon tape clockwise to all threaded pipe connections before tightening. For the faucet body, ensure you use a generous but neat amount of plumber's putty around the base to create a watertight seal against the tub deck.
My tub's access panel seems too small or is difficult to open. What should I do if I can't reach the plumbing easily?
Gaining proper access is crucial and sometimes the most challenging part. Use a headlamp for visibility and consider temporarily removing any surrounding trim or cabinet components if necessary. If space is extremely limited, you might need to carefully enlarge the access opening, ensuring it can be neatly covered afterward.
