Fontana Gold Concealed Shower Mixer Valve FAQ
Supply Orientation, Temperature Limiting & Concealed Valve Pressure Testing
This gold wall-mounted shower mixer combines a concealed brass valve,
ceramic temperature regulation, pressure balancing, and integrated hot-and-cold water control.
How should the hot and cold inlet orientation be verified during rough-in?
Confirm the designated hot and cold ports before connecting the G1/2-inch supplies, then flush each branch independently to prevent reversed temperature control and cartridge contamination.
How should the adjustable temperature limit stop be commissioned?
Operate the mixer under stable flowing conditions, measure the discharged water with a calibrated thermometer, and adjust the integral limit stop before securing the operating handle.
What concealed pressure testing is required before wall closure?
Pressure-test the brass valve body, inlet joints, and outlet connection before waterproofing and tiling, inspecting every concealed interface for leakage or pressure loss.
How should the pressure-balancing cartridge be evaluated during handover?
Run the shower while nearby fixtures are cycled and confirm that the regulating cartridge limits sustained temperature movement while maintaining stable flow and smooth handle control.
