Setup and Installation
Professional installation is recommended. Ensure all local plumbing codes are followed. Turn off the main water supply before starting installation.
Tools Required (Not Included):
- Adjustable Wrench
- Pipe Thread Sealant Tape (Teflon Tape)
- Phillips Head Screwdriver
- Level
- Measuring Tape
- Drill (if needed for mounting)
Installation Steps:
- Prepare the Wall: Ensure the wall cavity is ready for the built-in valve. The valve should be installed such that the "FINISHED WALL FLUSH WITH THIS SURFACE" marking on the valve body aligns with the finished wall surface.
- Install the Valve Body: Connect the hot and cold water supply lines to the marked inlets on the pressure balance valve (H for Hot, C for Cold). Connect the shower head outlet and handheld spray outlet lines. Use pipe thread sealant tape on all threaded connections. Secure the valve body to the wall framing using appropriate fasteners.
- Install Shower Arm: Thread the shower arm into the wall outlet, ensuring it is securely tightened and properly oriented. Apply thread sealant tape.
- Attach Shower Head: Thread the 10-inch square shower head onto the shower arm. The 360° rotation connection ball allows for angle adjustment. Hand-tighten, then use a wrench for a final snug fit, being careful not to overtighten.
- Install Handheld Shower Bracket: Mount the shower bracket holder to the wall at a comfortable height, ensuring it is level.
- Connect Handheld Shower and Hose: Attach one end of the shower hose to the handheld shower spray and the other end to the outlet on the valve body or a dedicated wall elbow. Place the handheld shower into its bracket.
- Install Trim Plate and Handle: Once the rough-in plumbing is complete and tested, install the decorative trim plate over the valve body. Secure it with the provided screws. Attach the handle to the valve stem, ensuring it operates smoothly.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. Operate the handle to switch between the shower head and handheld spray to ensure proper function.

Operating Instructions
Your WELLFOR shower system is designed for ease of use and optimal comfort.
Water Flow and Temperature Control:
- The single handle controls both water flow and temperature.
- To turn on the water and adjust flow, rotate the handle.
- To adjust temperature, rotate the handle left for hotter water and right for colder water. The pressure balance valve will maintain a consistent temperature to prevent sudden changes.
Diverter Function:
- The small knob above the main handle is the 2-way diverter.
- Rotate the diverter knob to switch water flow between the main shower head and the handheld spray.
- Ensure the diverter is fully engaged in one position for optimal water pressure from the selected outlet.

Maintenance
Regular cleaning and proper care will ensure the longevity and optimal performance of your WELLFOR shower system.
Cleaning the Finish:
- Clean the matte black finish with a soft, damp cloth and mild soap.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
Cleaning Nozzles:
- The shower head and handheld spray feature touch-clean nozzles. Simply rub the rubber nozzles with your finger or a soft brush to remove mineral buildup.
- For stubborn mineral deposits, a solution of equal parts white vinegar and water can be used. Soak the shower head (if removable) or apply the solution to the nozzles, let it sit for a few minutes, then scrub and rinse.

Troubleshooting
If you encounter any issues with your WELLFOR shower system, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged shower head nozzles; partially closed shut-off valve; low house water pressure. | Clean shower head nozzles. Ensure shut-off valves are fully open. Consult a plumber for house water pressure issues. |
| Water Leaks from Connections | Loose connections; insufficient thread sealant tape; damaged O-rings/gaskets. | Turn off water supply. Tighten connections. Reapply thread sealant tape. Inspect and replace O-rings/gaskets if damaged. |
| Inconsistent Water Temperature | Pressure balance cartridge issue; hot/cold water supply imbalance. | Ensure hot and cold water supplies are balanced. If problem persists, the pressure balance cartridge may need inspection or replacement by a qualified plumber. |
| Diverter Not Switching Properly | Mineral buildup in diverter; diverter cartridge issue. | Operate the diverter several times to dislodge any debris. If problem persists, the diverter cartridge may need inspection or replacement. |
If these solutions do not resolve the issue, please contact WELLFOR customer support for further assistance.
