The technician reinstalls the now-sealed shower arm into the fitting in the wall. He tightens it by hand initially, then uses the handle of his channel-lock pliers inserted into the arm's opening to get extra leverage for the final turns, ensuring it's snug. He then slides the escutcheon back against the wall, reinstalls the shower head (with fresh Teflon tape on its threads), and tightens it.

Goal: Properly install the sealed shower arm back into the wall

  • Do not forget to slide the escutcheon plate onto the shower arm before installing the shower head.

FAQs

What specific tools are essential for replacing a Delta Monitor shower faucet?

You'll primarily need a Phillips head screwdriver for trim removal and installation. A crucial specialized tool is an Arcan Hardened 3 in. Gear Puller AS3GP, which is often necessary for removing a stubborn old valve cartridge. Have penetrating oil and silicone grease ready as well.

What's the most important safety precaution I need to take before starting this project?

The most critical step is to completely shut off the water supply to the shower. This can be done at the main house shut-off valve or by turning off individual hot and cold water lines if available. Double-check that no water flows from the shower before proceeding to prevent flooding.

I'm a beginner. How difficult is this project, and how long should I expect it to take?

This project is classified as beginner difficulty, meaning it's manageable for those new to DIY. The estimated time for completion is around 3 hours. However, this can vary depending on the condition of your old faucet and any unexpected issues, so allow some extra time.

What should I do if my old shower cartridge is stuck and won't come out?

A common issue is a stubborn old cartridge. First, try applying penetrating oil around the cartridge base and let it sit for a few minutes to help loosen it. If it still doesn't budge, you will likely need to use a gear puller, such as the Arcan Hardened 3 in. Gear Puller AS3GP, to extract it safely without damaging the valve body.

It's okay, super text. No, let me do this. Screw it back down. Get it nice and snug. Put the shower head back on and turn the water on. Oh, don't forget your scutching. Do that before you put the shower head on. How many towels I've done that? Put the shower head on and forgot to put the escutching on. The last few turns can get a little tricky. So what I do is I put the channel lock handle in there and give you a little more leverage. I'm going to have to hold it back here so I'm going to put the camera down. So I'll hold it here and then I'll just turn with my channel locks. I'm going to tighten our own down for you. All right, got it all buttoned back up and shower head back on. I'll let it throw some Teflon around the threads too. Not the pipe, though. You can if you want to, but only time I like to go overboard with the pipe dope and Teflon is when it's behind the wall. I don't want to be returning.
