Prepare the new shower arm by wrapping the threaded end that goes into the wall with Teflon tape in a clockwise direction. Screw the arm into the wall fitting and hand-tighten. To secure it further without damage, place a rag over the arm and use slip-joint pliers to give it a final turn. Next, wrap Teflon tape around the threads on the other end of the arm. Screw the new showerhead onto the arm and tighten it by hand until it is snug.

FAQs

What additional materials or tools might I need beyond an adjustable wrench and cleaning cloths for this rainshower installation?

You will definitely need plumber's tape (also known as Teflon tape) to create a watertight seal on the shower arm threads. An old rag or towel is also useful to protect surfaces and catch any drips during the process.

What's the most common mistake beginners make when installing a new shower head, and how can I avoid it?

The most common mistake is overtightening the shower head, which can strip threads or crack the fixture. Tighten by hand until snug, then use an adjustable wrench for a final quarter to half turn, ensuring it feels secure without excessive force.

My old shower head is really stuck and won't unscrew. What's the best way to remove it without damaging my shower arm?

Ensure you're turning it counter-clockwise. If it's still stuck, try applying a penetrating lubricant (like WD-40) to the joint and letting it sit for 15-30 minutes. Use an adjustable wrench for leverage, but apply steady pressure rather than sudden jerks.

I installed my new rainshower head, but the water pressure still feels too low. What should I check?

Many new shower heads, especially rainshowers, come with a removable flow restrictor designed to conserve water. Carefully check your shower head's instructions for how to locate and remove this small plastic disc, as it can significantly improve pressure. Also, ensure your main house water valve is fully open.

Then you simply install the new trim kit. To prevent leaking, wrap any threaded ends with Teflon tape. Protect the finishes from scratches by wrapping them with a rag before tightening. Do the same on the tub spout if it's threaded.
