Before turning on the water supply to test for leaks, you must cap the shower head outlet. Take a threaded pipe nipple and an end cap. Apply Teflon tape to the threads of the nipple, then screw on the end cap and tighten with a wrench. Screw this capped nipple into the drop-ear elbow where the shower arm will eventually go. Once capped, you can slowly turn the main water supply back on and carefully inspect every connection point (at the valve and the drop-ear elbow) for any signs of dripping or leaks.

Goal: Test all new plumbing connections for leaks

  • Do not skip this step. It is critical to identify and fix leaks before closing up the wall.

FAQs

What specific tools and materials are essential for installing a Delta shower head, besides the new head itself?

You'll definitely need an adjustable wrench to remove the old head and tighten the new one. Crucially, have Teflon tape on hand for a watertight seal, and a soft cloth (like a microfiber cleaning cloth) to protect the finish of your new Delta shower head when using the wrench.

What is the most important safety precaution to take before beginning to replace my Delta shower head?

The absolute most critical step is to turn off the main water supply to your shower or, if possible, to your entire home. This prevents unexpected water sprays or potential flooding once you start removing the old shower head from the arm.

My newly installed Delta shower head is leaking around the connection point. What's the first thing I should check?

A leak usually indicates an issue with the seal. First, ensure you applied enough Teflon tape (typically 3-5 wraps clockwise) and that it's seated properly. Then, gently tighten the connection further with your adjustable wrench, making sure to protect the finish with a cloth.

The project mentions 45 minutes for a beginner. Is this realistic for someone who has never installed a shower head before?

Yes, 45 minutes is a realistic estimate for a beginner, assuming you have all your tools ready and follow the steps. Most of the time is spent carefully removing the old head and ensuring a good, leak-free seal with the new one. Don't rush applying the Teflon tape.

Otherwise, we're going to get wet. So I'm using a life of pipe here with an end cap. And I'm going to use some Teflon tape like we did before. And why am I doing this? Because this is how plumbers I work with do this. Okay. They use just a length of pipe and a cap. I'm going to Teflon tape it, get my crescent and tighten it up. They have plastic ones of these, by the way. I will link in the description. They're super cheap. But if you're going to leave it capped for a while, I just like
