Fontana Brushed Nickel 3-Way Concealed Shower Mixer FAQ
Three-Outlet Balancing, Diverter Indexing & Concealed Valve Commissioning
This brushed nickel wall-mounted shower mixer combines a one-piece brass valve body,
ceramic flow regulation, and an integrated three-way diverter for controlled outlet selection.
How should the three concealed outlet branches be coordinated during rough-in?
Identify and label each branch for its assigned shower function, maintain unrestricted pipe routing, and verify that every connection remains accessible for pressure testing before wall closure.
What confirms correct three-way diverter indexing after installation?
Cycle the diverter through all indexed positions under flowing conditions and confirm that each position activates the intended outlet while isolating the two inactive branches.
What should be tested before waterproofing and applying the finished wall?
Pressure-test the brass valve body, hot and cold inlets, diverter chamber, threaded joints, and all three outlet connections while the complete concealed assembly remains visible.
How should the ceramic valve core be protected during commissioning?
Flush the supply and outlet lines before operating the cartridge to remove pipe scale, solder particles, sealing compound, and construction debris that could damage the ceramic surfaces.
