Installation Steps:
- Prepare the Shower Arm: Ensure the shower arm is clean and free of debris. Apply Teflon tape (not included) to the threads of the shower arm for a secure, leak-free connection.

5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose connections, improperly seated O-rings, incompatible thread type. | Ensure all connections are hand-tightened. Check that O-rings are correctly placed. If leakage persists, verify your shower arm's thread type (standard 1/2" is required). Apply more Teflon tape if necessary. |
| Reduced Water Flow | Clogged filter cartridge, mineral buildup in shower head. | Replace the filter cartridge (M91010-1). Clean your shower head to remove any mineral deposits. |
| No Improvement in Water Quality | Expired filter cartridge, extremely high levels of contaminants. | Ensure the filter cartridge is not past its recommended replacement period (6 months). Replace with a new M91010-1 cartridge. |
