Fontana Gold Thermostatic 2 Knob 3 Way Mixing Valve FAQ
Thermostatic Setpoint, Three-Way Routing & Concealed Valve Commissioning
This gold concealed shower mixer combines pressure-balanced thermostatic regulation,
dual-handle control, a ceramic cartridge, and three-way water distribution.
How should the thermostatic temperature setpoint be calibrated?
Operate the valve under normal flowing conditions, verify the mixed-water temperature using a calibrated thermometer, and adjust the cartridge and integral temperature limit stop before securing the control handle.
How should the three outlet circuits be tested before wall closure?
The rainfall shower, hand shower, and tub-spout lines should be individually identified, flushed, pressure-tested, and connected to their designated diverter ports before installing the finished wall and faceplate.
What determines the correct concealed valve mounting depth?
The brass rough-in body should be positioned relative to the final finished-wall plane so the gold faceplate seats evenly and both control knobs engage their stems without binding or excessive projection.
How should thermostatic recovery be verified during commissioning?
Operate each outlet while nearby fixtures are cycled and confirm rapid temperature correction, stable mixed-water delivery, unrestricted flow, and positive diverter engagement during hot- and cold-supply pressure changes.
