- 1 x Brass Flange

Setup and Installation
Follow these steps for proper installation of your shower arm:
- Prepare the existing shower pipe: Ensure the existing shower pipe extending from the wall is clean and free of debris. Turn off the main water supply to the shower.
- Apply Thread Seal Tape: Wrap the provided thread seal tape clockwise around the threaded end of the shower arm that will connect to the wall pipe. Apply 3-5 layers for a secure, leak-free seal.
- Thread Shower Arm into Wall: Carefully thread the shower arm into the existing shower pipe in the wall. Hand-tighten first, then use the provided Allen wrench inserted into the shower arm outlet for leverage to tighten securely. Ensure the arm is oriented correctly for your shower head.
- Slide Flange Over Shower Arm: Slide the brass flange over the shower arm, pushing it flush against the wall. The flange is designed to cover the wall opening for a finished appearance.
- Secure Flange with Set Screw: Locate the small set screw on the flange. Use the Allen wrench to tighten this screw, securing the flange firmly to the shower arm and preventing it from sliding or spinning.
- Attach Shower Head: Apply thread seal tape to the threaded end of the shower arm where your shower head will attach. Thread your rain shower head onto the arm and tighten securely.
- Test for Leaks: Turn the main water supply back on and check all connections for leaks. If leaks occur, turn off the water, re-apply thread seal tape, and re-tighten connections.

Operating Instructions
Once installed, the HammerHead Showers 16 Inch Extended Shower Arm functions as a fixed extension for your rain shower head. It positions the shower head further from the wall and directly overhead, enhancing the rainfall effect. Operate your shower as usual using your shower valve controls.

Maintenance
To ensure the longevity and appearance of your shower arm:
- Cleaning: Clean the shower arm and flange regularly with a soft cloth and mild, non-abrasive soap.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or chemical solvents, as these can damage the finish.
- Inspect Connections: Periodically check the connections for any signs of loosening or leaks. Re-tighten if necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leaks at wall connection | Insufficient thread seal tape or loose connection. | Turn off water, remove arm, re-apply 3-5 layers of thread seal tape, and re-tighten securely. |
| Flange slides down the arm | Set screw not tightened. | Tighten the set screw on the flange using the provided Allen wrench. |
| Shower arm feels unstable or sags | Inadequate support from in-wall plumbing or improper tightening. | Ensure the shower arm is fully threaded and tightened. If the in-wall plumbing is not secure, professional reinforcement may be required. |
