Fontana Rose Gold Thermostatic 2 Knob 3 Way Mixing Valve FAQ
Thermostatic Setpoint, Three-Way Port Mapping & Concealed Trim Alignment
This rose gold concealed shower mixer combines pressure-balanced thermostatic regulation,
dual-handle operation, a ceramic cartridge, and three-way outlet distribution.
How should the thermostatic setpoint be calibrated after installation?
Operate the valve under stable flowing conditions, measure the mixed-water temperature with a calibrated thermometer, and adjust the cartridge and integral limit stop before securing the temperature-control knob.
How should the three diverter ports be mapped during concealed rough-in?
Identify the rainfall shower, hand-shower, and spout branches before connection, then flush and pressure-test each circuit independently to prevent crossed outlets or concealed routing errors.
What should be checked before installing the rose gold faceplate?
Confirm that the brass rough-in body is level and positioned from the final finished-wall plane so the trim seals evenly and both controls engage without rubbing or excessive projection.
How should pressure-balancing recovery be tested during handover?
Operate each outlet while nearby fixtures are cycled and verify rapid temperature correction, stable mixed-water delivery, unrestricted flow, and positive diverter indexing during supply-pressure changes.
