Fontana Creteil Gun Metal Gray Round Rain Shower Head FAQ
1.75 GPM Flow Verification, Inlet Sealing & Spray-Face Commissioning
This gun metal gray round rain shower head combines a 9.87-inch metal
spray face, single-function 1.75 GPM rainfall delivery, Master Clean
easy-service nozzles, an adjustable swivel joint, and a standard
1/2-inch NPT connection for wall- or ceiling-arm installation.
What branch-line preparation is required before installing the shower head?
Remove the temporary shower-arm cap and flush the open branch until
solder particles, pipe scale, sealing compound, construction debris,
and stagnant water are completely discharged. This prevents initial
blockage of the internal flow-control passage and nozzle field.
How should the 1/2-inch NPT inlet be tightened without marking the gun metal gray finish?
Inspect the male threads, apply approved thread sealant sparingly,
and tighten through the inlet connection using protected tools.
Avoid gripping the finished rim, swivel housing, or spray face,
since installation torque can damage the finish or joint alignment.
How should the 1.75 GPM rated output be confirmed after installation?
Operate the shower at stabilized dynamic pressure, purge trapped air,
and conduct a timed volumetric collection test. Reduced delivery may
indicate upstream pressure loss, a restricted branch, debris at the
inlet, mineral accumulation, or obstruction within the flow passage.
What indicates correct commissioning of the Master Clean nozzle field?
Confirm uniform rainfall coverage across the complete 9.87-inch
spray face without inactive outlets, weak perimeter zones, pulsing,
or concentrated jets. Restricted nozzles should be gently wiped,
flushed, and retested before final installation acceptance.
