Prepare the new plumbing connections. Wrap the threads of all new brass fittings with Teflon tape to ensure a watertight seal. In this video, a new assembly is created using a T-fitting, a nipple, a 90-degree elbow, and a small ball valve. The ball valve is added to make future switch replacements easier. Assemble these fittings tightly using wrenches.

Goal: Create a new connection point for the switch

  • Wrap Teflon tape in the same direction you will be tightening the fitting (clockwise) to prevent it from unwrapping.

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.

Now, I'm going to be doing something a little different. Rather than having a short stubby here, I'm going to build this up over and up. Right here, I made a little model of it here. This is what I'm making right here. It's going to come up. I'm going to have a valve here so I can shut this off so I don't have to empty the whole system on. Next time I do this, and then the pressure switch is going right up here. Another thing is when you're changing these, when you're changing these, always use brass. Never use galvanized steel. It's garbage. When it water and steel, it just doesn't mix. It just rusts and corrodes. Always use brass when you're doing any kind of plumbing like this. Always use a teflon tape made for plumbing. The first piece we're going to put on there is this one here. All right, I decided to go this route.
