Fontana Forbach Brushed Gold 3-Function Shower Mixer FAQ
Three-Outlet Routing, 35 mm Ceramic Control & Concealed Valve Testing
This brushed gold wall-mounted shower mixer combines a solid brass concealed valve,
a 35 mm ceramic cartridge, and three independently controlled shower-function outlets.
How should the three concealed outlet branches be assigned?
Route and label each 1/2-inch outlet for its designated shower function, then verify that the three controls operate the intended rainfall shower, hand shower, and auxiliary outlet before wall closure.
How should the 35 mm ceramic cartridge be commissioned?
Flush the hot and cold supply lines, operate the temperature control throughout its 20–50°C range, and confirm smooth cartridge movement only after debris has been cleared from both inlets.
How should outlet isolation be checked under operating pressure?
Activate each shower function separately and confirm stable discharge through the selected branch without cross-flow, pressure migration, dripping, or unintended delivery through either inactive outlet.
Which concealed components require testing before waterproofing?
Pressure-test the hot and cold inlets, solid brass valve body, ceramic cartridge housing, three function-control seals, and every 1/2-inch outlet connection while the assembly remains accessible.
