Locate your home's main water supply shut-off valve, which is typically found outside near the water meter. Turn the valve to the 'off' position to stop the flow of water to the house. This is a crucial safety step to prevent water from spraying inside your bathroom during the replacement.

Goal: Shut off water to the house

  • The last thing you want in your bathroom is the Trevi Fountain. Make sure the water is completely off.

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.
