Setup and Installation
The Westbrass SAF-07 is designed for easy installation with most standard US 1/2-inch 14NPSM pipe threads, compatible with fixed wall mount and ceiling shower heads.
Required Tools:
- Adjustable wrench or pliers
- Plumber's tape (Teflon tape)
Installation Steps:
- Turn off Water Supply: Locate the main water shut-off valve for your shower or entire home and turn it off to prevent water flow during installation.
- Remove Existing Shower Head: Carefully unscrew your current shower head from the shower arm. You may need an adjustable wrench or pliers.
- Clean Threads: Ensure the threads on the shower arm are clean and free of old plumber's tape or debris.
- 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 Filter Housing: Screw the Westbrass SAF-07 filter housing onto the shower arm. Hand-tighten first, then use a wrench for a final quarter to half turn. Do not overtighten.
- Apply Plumber's Tape to Filter Outlet: Wrap plumber's tape clockwise around the threads of the filter housing's outlet where the shower head will attach.
- Attach Shower Head: Screw your shower head onto the outlet of the Westbrass SAF-07 filter housing. Hand-tighten, then use a wrench for a final quarter to half turn.
- Restore Water Supply: Slowly turn the main water supply back on.
- Check for Leaks: Turn on the shower and check all connections for any leaks. If leaks occur, turn off the water, re-tape the threads, and re-tighten the connections.

Operating Instructions
Once installed, the Westbrass SAF-07 operates automatically with your shower. It maintains a flow rate of 1.8 Gallons Per Minute (GPM), ensuring a consistent and comfortable shower experience while filtering your water.
No special operation is required beyond normal shower use. The filter works continuously to reduce impurities as water passes through it.
Maintenance
Regular replacement of the filter cartridge is crucial to maintain optimal performance and water quality. The filter cartridge should be replaced every six (6) months or after 10,000 gallons of use, whichever comes first. You may also consider replacement if you notice a decrease in water quality or flow.
Filter Cartridge Replacement Steps:
- Turn off Water Supply: Turn off the main water shut-off valve to your shower.
- Remove Shower Head: Unscrew your shower head from the filter housing.
- Open Filter Housing: Carefully unscrew the bottom cap of the filter housing.
- Remove Old Cartridge: Extract the used filter cartridge from the housing. Dispose of it properly.
- Insert New Cartridge: Place a new Westbrass SHF replacement filter cartridge into the housing, ensuring it is seated correctly.
- Close Filter Housing: Screw the bottom cap back onto the filter housing. Hand-tighten, then use a wrench for a final quarter to half turn. Do not overtighten.
- Reattach Shower Head: Screw your shower head back onto the filter housing.
- Flush New Filter: Slowly turn the water supply back on. Run hot water through the shower for approximately one (1) minute to flush the new filter cartridge.
- Check for Leaks: Inspect all connections for leaks.
Replacement filter units compatible with SAF-07 are designated as SHF. Ensure you purchase the correct replacement cartridge for continued performance.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks from connections | Loose connections, insufficient plumber's tape, damaged O-rings. | Turn off water, re-tape threads, and re-tighten connections. Check O-rings for damage and replace if necessary. |
| Reduced water flow | Clogged filter cartridge, mineral buildup in shower head. | Replace the filter cartridge. Clean your shower head by soaking it in a descaling solution if mineral buildup is suspected. |
| Water quality does not improve | Expired filter cartridge, incorrect filter type. | Ensure the filter cartridge is not past its recommended lifespan (6 months or 10,000 gallons). Verify you are using a genuine Westbrass SHF replacement cartridge. |
