3. What's Included
The Moen 6345BL package includes:
- One (1) Moen 6345BL Fixed Rainshower Head
Note: Additional components such as shower arms or extension pipes are sold separately.
4. Installation
The Moen 6345BL Fixed Rainshower is designed for straightforward installation, typically screwing onto an existing shower arm. No specialized tools or plumbing experience beyond basic DIY skills are generally required.
- Preparation: Ensure the water supply to your shower is turned off at the main valve.
- Remove Old Showerhead: Unscrew your existing showerhead from the shower arm. You may need a wrench for this. Clean any old sealant or debris from the shower arm threads.
- Apply Plumber's Tape: Wrap plumber's tape (Teflon tape) clockwise around the threads of the shower arm. This helps create a watertight seal.
- Attach New Showerhead: Hand-tighten the Moen 6345BL Rainshower onto the shower arm. Ensure it is straight and securely attached.
- Final Tightening: Use a wrench to gently tighten the showerhead an additional quarter to half turn. Do not overtighten, as this can damage the threads.
- Test for Leaks: Turn the water supply back on and check for any leaks around the connection. If leaks occur, tighten slightly more or reapply plumber's tape.

6. Maintenance
Regular cleaning will help maintain the appearance and performance of your Moen rainshower.
- General Cleaning: Clean the showerhead regularly with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Silicone Nozzle Cleaning: The silicone nozzles are designed for easy cleaning. If mineral buildup occurs, gently rub the nozzles with your fingers or a soft brush to dislodge deposits. This helps maintain consistent water flow.
- Finish Care: To preserve the Matte Black finish, wipe the showerhead dry after each use to prevent water spots.
7. Troubleshooting
If you encounter issues with your Moen 6345BL Rainshower, consider the following common solutions:
- Low Water Pressure: Check if the silicone nozzles are clogged with mineral deposits. Gently rub them to clear any blockages. Ensure your main water supply valve is fully open.
- Leaking: If water is leaking from the connection point, ensure the showerhead is properly tightened and that plumber's tape was applied correctly. Re-tape and re-tighten if necessary.
- Inconsistent Spray: This is often due to clogged nozzles. Clean the silicone nozzles as described in the Maintenance section.
