Fontana Chatou Gun Metal Gray Rain Shower Head FAQ
1.75 GPM Verification, NPT Joint Sealing & Spray-Face Commissioning
This gun metal gray 8-inch rain shower head combines brass construction,
a 1.75 GPM single-function rain spray, air-induction technology,
a cleanable spray face, and a standard 1/2-inch NPT connection.
How should the concealed shower-arm connection be prepared?
Verify that the drop-ear fitting is securely supported, flush the branch line, inspect the 1/2-inch NPT threads, and apply approved thread sealant without allowing excess material to enter the shower-head waterway.
How should the specified 1.75 GPM discharge be field-verified?
Stabilize the supply pressure, purge trapped air, and complete a timed volumetric test at the outlet. Low measured flow may indicate branch-line pressure loss, inlet debris, restricted piping, or an obstructed internal flow regulator.
What should be checked across the 8-inch spray face?
Confirm uniform discharge from the complete nozzle field without isolated weak zones, lateral jetting, pulsing, partial blockage, or uneven droplet formation that could indicate trapped debris or mineral accumulation.
How should the gun metal gray finish and spray nozzles be maintained?
Use a soft cloth and nonabrasive cleaner on the finished surfaces, loosen nozzle deposits gently, and flush the head afterward. Avoid aggressive chemicals, scouring pads, and metal tools that could damage the coating.
