Fontana Brushed Gold Thermostatic 2 Knob 3 Way Mixing Valve FAQ
Thermostatic Calibration, Three-Way Routing & Concealed Valve Commissioning
This brushed gold concealed shower mixer combines pressure-balanced thermostatic control,
dual-handle operation, a ceramic regulating cartridge, and three-way outlet distribution.
How should the thermostatic cartridge be calibrated after installation?
The valve should be operated under normal flowing conditions and checked with a calibrated thermometer, then the cartridge position and adjustable temperature limit stop should be set before the temperature handle is secured.
How should the three outlet circuits be coordinated during rough-in?
The rainfall shower, hand shower, and tub-spout lines should be clearly identified, independently flushed, pressure-tested, and connected to their designated diverter ports before the finished wall is closed.
What determines the correct concealed valve installation depth?
The brass rough-in body must be positioned from the final finished-wall plane so the brushed gold faceplate seats evenly and both control knobs engage their stems without binding or excessive projection.
How should pressure-balancing performance be verified during handover?
Each outlet should be operated while nearby fixtures are cycled to confirm stable mixed-water temperature, positive diverter engagement, unrestricted flow, and rapid thermostatic correction during hot- or cold-supply pressure changes.
