Slowly turn the main water supply back on. Carefully inspect all the new plumbing connections around the thermostatic mixing valve for any signs of leaks or drips using a flashlight if needed. If any leaks are found, immediately turn off the water and reseal the connections. Once confirmed leak-free, go to the bathtub. Turn on the faucet and let the water run, checking that the temperature is tempered. Test the diverter to switch water flow to the handheld showerhead and ensure it works. Finally, press the buttons to activate the air and water whirlpool jets to confirm all tub functions operate correctly with the new plumbing.

Goal: System Testing

  • Turn the water on slowly to pressurize the system gradually, which can help identify small leaks before they become major problems.

FAQs

Beyond a screwdriver and Teflon tape, what other tools or materials might I unexpectedly need for this shower diverter installation?

While a multi-screwdriver and Teflon tape are essential, it's wise to have an adjustable wrench or pliers on hand for securely tightening the new diverter. You might also find a utility knife useful for cutting away old caulk, and a flashlight to better see into tight spaces.

What should I do if I can't find the shut-off valves for my shower or entire house?

If you can't locate local shut-off valves for your shower, you'll need to turn off the main water supply to your entire house. This is typically found near your water meter or where the main water line enters your home. Always ensure the water is completely off before starting work to prevent flooding.

I've installed the new diverter, but it's leaking when I turn the water back on. What's the most common reason for this?

The most common cause for leaks after installation is insufficient tightening or improper application of Teflon tape. Ensure you've wrapped the Teflon tape clockwise around the threads 3-5 times, and gently but firmly tighten the diverter valve with a wrench or pliers until snug, without over-tightening.

Is this really a beginner-friendly project, and can I realistically complete it in 3 hours?

Yes, this project is generally beginner-friendly as it primarily involves unscrewing and screwing parts. The 3-hour estimate is reasonable for someone with basic DIY skills, but prepare for potential delays if old parts are stuck or if you need to locate a main water shut-off.
