Fontana Gun Metal Gray Rain Shower Head FAQ
1.75 GPM Flow Testing, NPT Joint Sealing & Spray-Face Commissioning
This gun metal gray 8-inch round rain shower head combines brass
construction, a water-efficient 1.75 GPM single-function spray,
Katalyst air-induction technology, a MasterClean spray face, and
a standard 1/2-inch NPT inlet.
How should the concealed shower-arm outlet be prepared before installation?
Confirm the drop-ear elbow is securely anchored and perpendicular to the finished wall. 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 verified?
Stabilize the operating pressure, purge trapped air, and perform a timed volumetric test. Reduced flow may indicate branch-line pressure loss, construction debris, mineral accumulation, or restriction at the internal flow-control component.
What confirms balanced hydraulic distribution across the 8-inch spray face?
Verify uniform discharge across the complete nozzle field without inactive outlets, isolated weak zones, lateral jetting, pulsing, or uneven droplet formation. Irregular coverage normally requires flushing or spray-face cleaning.
How should the gun metal gray finish and MasterClean outlets be maintained?
Clean finished surfaces with a soft cloth and neutral nonabrasive solution. Gently loosen mineral deposits from the outlets and flush afterward. Avoid acidic cleaners, abrasive pads, metal tools, and concentrated descaling chemicals.
