Fontana Chatou Matte Black Rain Shower Head FAQ
1.75 GPM Testing, 1/2-Inch NPT Sealing & Rain-Spray Commissioning
This matte black 8-inch round rain shower head combines brass construction,
a water-efficient 1.75 GPM discharge, single-function rain coverage,
air-induction spray technology, and a standard 1/2-inch NPT connection.
How should the concealed shower-arm fitting be prepared before installation?
Confirm the drop-ear elbow is securely anchored and aligned perpendicular to the finished wall, flush the branch piping, inspect the 1/2-inch NPT threads, and apply approved sealant without introducing excess material into the waterway.
How should the specified 1.75 GPM flow rate be field-verified?
Stabilize the operating pressure, purge trapped air, and complete a timed volumetric test. A low reading may indicate supply pressure loss, pipe restriction, inlet debris, mineral buildup, or obstruction at the internal flow regulator.
What should be checked across the complete 8-inch spray face?
Verify uniform discharge from the full nozzle field without weak sections, sideways jets, pulsing, uneven droplet formation, or inactive outlets that could indicate debris, scale accumulation, or insufficient branch-line pressure.
How should the matte black finish and spray outlets be maintained?
Clean the exterior with a soft cloth and nonabrasive solution, gently loosen deposits from the flexible outlets, and flush afterward. Avoid acidic chemicals, abrasive pads, metal tools, and aggressive descaling agents.
