Connect Valve to Bathtub Plumbing — Accessing the Plumbing
Part of project
How to Replace a Mobile Home Garden Tub Faucet · Step 2 of 9
In this video
Access the plumbing behind the bathtub through the access panel. Identify the hot and cold water supply lines. Cut the existing CPVC pipes to insert T-fittings. Using CPVC primer and cement, glue the T-fittings into the hot and cold lines. Connect short pieces of CPVC pipe and elbows as needed to route the water from the T-fittings to the corresponding hot (H) and cold (C) inlets of the thermostatic mixing valve. Connect the mixed water outlet (marked 'MIX' or similar) of the valve to the bathtub faucet's water supply line. Ensure all connections are secure and allow the cement to fully cure as per the manufacturer's instructions before turning on the water.
Goal: Install Mixing Valve
- Work in a well-ventilated area when using CPVC primer and cement due to strong fumes.
- Double-check that the hot water line is connected to the 'H' inlet and the cold water line to the 'C' inlet on the valve.

FAQs
What specialized tools, beyond basic pliers and screwdrivers, are crucial for this mobile home garden tub faucet replacement?
A powerful flashlight, like the Panther Vision FLATEYE, is essential for illuminating the confined, often dark, plumbing access area. Husky soft-jaw pliers are also highly recommended to prevent scratching the new faucet's finish during tightening. Don't forget a sturdy bucket, such as the Unger 6 Gal. Heavy-Duty Plastic Bucket, to catch any residual water.
What are the most critical safety precautions I should take before and during this project, especially in a mobile home setting?
Always begin by completely shutting off the main water supply to your mobile home and draining the lines to prevent unexpected water damage. Exercise caution when working in tight, enclosed spaces, ensuring you have proper lighting and ventilation. Have plenty of paper towels readily available for immediate cleanup of spills to protect your subfloor.
The project is rated 'beginner' but has an estimated time of 6 hours. What aspects contribute to this duration, and what common challenges might a beginner face?
While the individual plumbing steps are straightforward, much of the time is spent accessing the plumbing through a potentially tight access panel and meticulously disconnecting old, possibly corroded fittings. A beginner might also spend extra time ensuring proper sealing with plumber's putty and Teflon tape, and then thoroughly testing for leaks, which are critical steps for a successful outcome.
What are the most common mistakes beginners make when replacing a tub faucet, particularly concerning leaks, and how can I prevent them?
A frequent mistake is inadequate sealing. Always apply Teflon tape clockwise to all threaded pipe connections and a generous bead of Oatey Plumber's Putty around the base of the faucet before securing it to the tub deck. Ensure connections are snug—don't overtighten plastic fittings, but make metal ones firm—and double-check all connections for drips during your leak test.
