Fontana Champagne Thermostatic 2 Knob 3 Way Mixing Valve FAQ
Temperature Limit Calibration, Three-Way Routing & Pressure Stability
This champagne concealed shower mixer combines thermostatic temperature regulation,
pressure-balanced operation, dual controls, and three-way water distribution.
How should the integral temperature limit stop be commissioned?
Operate the valve under normal flow, measure the mixed-water temperature with a calibrated thermometer, and adjust the integral limit stop before securing the temperature-control handle.
How should the rainfall, hand shower, and spout circuits be identified?
Each outlet pipe should be permanently labeled, independently flushed, pressure-tested, and connected to its designated diverter port before the concealed valve cavity and finished wall are closed.
What protects the ceramic cartridge from commissioning debris?
Hot and cold supply lines must be thoroughly flushed before final valve connection, while inlet stops and strainers should be inspected to prevent pipe scale or construction debris from restricting cartridge movement.
How should thermostatic recovery be verified during project handover?
Cycle nearby fixtures while each outlet operates and confirm that the valve rapidly compensates for supply-pressure changes without sustained temperature drift, flow interruption, or unintended diverter movement.
