Fontana Gun Metal Gray Thermostatic 2 Knob 3 Way Mixing Valve FAQ
Thermostatic Recovery, Three-Way Routing & Concealed Valve Depth
This gun metal gray concealed shower mixer combines pressure-balanced thermostatic regulation,
dual-handle control, a ceramic cartridge, and three-way water distribution.
How should the thermostatic cartridge be calibrated after rough-in?
Run the valve under normal flowing conditions, verify the mixed-water temperature with a calibrated thermometer, and adjust the ceramic cartridge and integral temperature limit stop before securing the temperature handle.
What should be verified before connecting the three outlet circuits?
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.
How is the correct concealed mounting depth established?
Position the brass rough-in body from the final finished-wall plane so the gun metal gray faceplate seats evenly and both control knobs engage their valve stems without binding or excessive projection.
How should pressure-balancing response be tested at handover?
Operate each outlet while nearby fixtures are cycled and confirm rapid thermostatic correction, stable mixed-water delivery, unrestricted flow, and positive diverter engagement during hot- and cold-supply pressure changes.
