Fontana Black Bronze 2-Way Concealed Shower Mixer FAQ
Dual-Outlet Isolation, Diverter Sealing & Concealed Valve Commissioning
This black bronze wall-mounted shower mixer combines a one-piece brass valve body,
ceramic flow regulation, and an integrated two-way diverter for controlled outlet selection.
How should the two outlet branches be identified during concealed rough-in?
Label each branch according to its assigned shower function and verify that the diverter positions correctly correspond with the overhead shower, hand shower, or secondary outlet before wall closure.
What confirms proper hydraulic isolation between the two shower outlets?
Operate each diverter position under full flow and confirm that the selected branch receives stable discharge while the inactive branch remains isolated without dripping, bypass, or cross-flow.
Which concealed components require pressure testing before waterproofing?
Test the one-piece brass valve body, hot and cold inlet joints, diverter chamber, and both outlet connections while exposed, checking every threaded seal for leakage or pressure decay.
How should the ceramic valve core be protected during system start-up?
Flush the supply pipes and outlet branches before final cartridge operation to remove scale, solder residue, sealing compound, and construction debris that could score the ceramic sealing surfaces.
