Fontana Black Bronze 2-Way Concealed Shower Mixer FAQ
Dual-Function Routing, Cartridge Protection & Concealed Joint Testing
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 shower outlet selection.
How should the two shower-function outlets be mapped during rough-in?
Mark each concealed branch for its assigned shower head or hand shower, then confirm that the corresponding diverter position activates the intended outlet before the wall is closed.
What should be checked when commissioning the two-way diverter?
Cycle both indexed positions under operating pressure and verify smooth rotation, stable discharge, positive outlet selection, and complete isolation of the inactive waterway.
Which connections require testing before waterproofing?
Pressure-test the hot and cold inlets, brass mixer body, internal diverter chamber, threaded seals, and both outlet branches while the complete concealed assembly remains exposed.
How can installation debris be kept away from the ceramic cartridge?
Flush both supply pipes and outlet branches before final operation to remove scale, solder fragments, sealing compound, and construction residue that could damage the ceramic sealing faces.
