Please read this manual thoroughly before beginning installation or use, and retain it for future reference. Proper installation and care will ensure optimal performance and longevity of your product.
2. Safety Information
- Always turn off the main water supply before attempting any plumbing installation or repair.

3. Package Contents
Verify that all components are present before beginning installation:
- Moen 21313 Multi-Function Shower Head (Chrome)
- Washer/Gasket (pre-installed or separate)
Note: Additional plumbing fixtures, such as a shower arm, are typically sold separately.
4. Setup and Installation
Installation of the Moen 21313 shower head is a straightforward process. No specialized tools are typically required beyond a wrench for removing an existing shower head, if applicable, and plumber's tape.
Tools You May Need:
- Adjustable Wrench (for removing old shower head)
- Plumber's Tape (PTFE tape)
- Soft Cloth
Installation Steps:
- Prepare the Shower Arm: If replacing an existing shower head, turn off the water supply to your shower. Unscrew the old shower head from the shower arm. Clean any debris or old plumber's tape from the threads of the shower arm.
- Apply Plumber's Tape: Wrap plumber's tape clockwise around the threads of the shower arm 3-4 times. This helps create a watertight seal.
- Attach the New Shower Head: Ensure the washer/gasket is properly seated inside the shower head's connector. Screw the Moen 21313 shower head onto the shower arm by hand.
- Tighten: Hand-tighten the shower head until it is snug. Avoid overtightening, as this can damage the threads or the shower head. A wrench may be used for a final quarter-turn if necessary, but excessive force is not recommended.
- Test for Leaks: Turn on the water supply and check for any leaks around the connection point. If leaks occur, tighten slightly more or reapply plumber's tape.

5. Operating Instructions
The Moen 21313 Multi-Function Shower Head features three distinct spray patterns to customize your showering experience.
Changing Spray Patterns:
To switch between the available spray patterns, locate the lever or dial on the face or side of the shower head. Gently rotate or click this mechanism to cycle through the three settings. Each setting provides a different water flow and sensation.
- Setting 1: Typically a concentrated, invigorating spray.
- Setting 2: Often a wider, full-coverage spray for a relaxing experience.
- Setting 3: May be a combination spray or a targeted massage spray.
Experiment with each setting to find your preferred water delivery.
6. Maintenance
Regular cleaning and maintenance will help preserve the finish and functionality of your Moen shower head.
Cleaning the Finish:
- Clean the chrome finish with a soft, damp cloth and mild soap.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Avoid abrasive cleaners, harsh chemicals, scouring pads, or brushes, as these can damage the finish.
Cleaning the Spray Nozzles:
Over time, mineral deposits from hard water can accumulate in the spray nozzles, affecting water flow. The flexible rubber nozzles on this shower head are designed for easy cleaning.
- Gently rub the rubber nozzles with your finger or a soft brush to dislodge mineral buildup.
- For more stubborn deposits, you can soak the shower head in a solution of equal parts white vinegar and water for a few hours, then scrub and rinse. Ensure the shower head is fully dry before reinstallation if removed.
7. Troubleshooting
Refer to the table below for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water pressure | Mineral buildup in nozzles; partially closed water valve; low household water pressure. | Clean spray nozzles (see Maintenance); ensure water supply valve is fully open; consult a plumber for household water pressure issues. |
| Leaking at connection point | Loose connection; insufficient plumber's tape; damaged washer/gasket. | Tighten connection slightly; reapply plumber's tape; inspect and replace washer/gasket if damaged. |
| Difficulty changing spray patterns | Mineral buildup in the selector mechanism. | Soak the shower head in a vinegar solution to dissolve mineral deposits, then operate the selector repeatedly to free it. |
