4. Installation Instructions
Professional installation is recommended. Ensure all local plumbing codes are followed. Turn off the main water supply before starting any installation work.
4.1. Valve and Trim Installation
The thermostatic mixing valve is the core of your shower system. Proper installation is critical for optimal performance and safety.
- Prepare the Rough-in: Ensure the valve is installed at the correct depth within the wall (2 9/16" (65 mm) min - 2 15/16" (75 mm) max). An incorrect depth can lead to malfunction after tiling.
- Connect Water Lines: Connect the hot water inlet (left) and cold water inlet (right) to the valve. Standard connections are 1/2-14" NPT for USA/Canada and G1/2" for Europe.
- Flush Pipes: Before connecting to the valve, flush the two inlet pipes for two minutes to prevent blockage.
- Apply Teflon Tape: Wrap Teflon tape for at least 12 turns on all threaded connections to prevent leaks.
- Leakage Test: Insert plugs and perform a water test to ensure no leakage at any joint.
- Pressure Test: Test water pressure and flush outlet pipes for one minute.
- Install Trim: Once tiling is complete, install the trim plate and handles. Ensure the embedded box is flush with the tile surface.

5. Operation
Your EVERSTEIN Thermostatic Shower System is designed for ease of use and precise control.
- Temperature Control: Use the lower handle to adjust the water temperature. The thermostatic valve maintains your desired temperature, preventing sudden changes. The 100°F (38°C) safety lock can be overridden by pressing the button for higher temperatures.
- Flow Control: Use the upper handle to turn the water on/off and adjust the flow rate.
- Function Selection: The middle handle allows you to switch between the 12-inch rainfall shower head, 6-inch shower head, and handheld shower. You can also operate two functions simultaneously.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your shower system.
- Cleaning: Clean the shower heads and trim with a soft cloth and mild soap or a non-abrasive cleaner. Avoid harsh chemicals, abrasive cleaners, or scouring pads, as these can damage the finish.
- Mineral Deposits: For shower heads with rubber nozzles, gently rub the nozzles to dislodge mineral deposits. For stubborn deposits, soak the shower head in a solution of white vinegar and water.
- Thermostatic Cartridge: If temperature control becomes erratic, the thermostatic cartridge may need cleaning or replacement. Consult a professional plumber for this service.
7. Troubleshooting
