Fontana Bolln Gun Metal Gray Rain Shower Head FAQ
2.5 GPM Testing, Swivel Alignment & Round Rainfall Spray Commissioning
This gun metal gray round shower head combines durable metal
construction, an 11-3/4-inch rainfall spray face, single-function
2.5 GPM discharge, and a standard threaded inlet for contemporary
residential, hospitality, and specification-driven shower projects.
How should the shower supply branch be flushed before installation?
Remove the finished shower head and flush the shower-arm branch
until pipe scale, solder residue, construction debris, and excess
thread-sealing compound are fully discharged. Inspect the threaded
outlet before connecting the finished gun metal gray fixture.
How should the swivel inlet and round spray face be aligned?
Confirm that the shower arm projects squarely without lateral
loading. Seal the threaded joint sparingly, adjust the swivel until
the 11-3/4-inch spray face is level, and avoid transferring excessive
tightening torque through the finished metal body.
How should the specified 2.5 GPM discharge be field-verified?
Stabilize the dynamic supply pressure, purge entrained air, and
perform a timed volumetric test at the shower head. Reduced delivery
may indicate branch-line pressure loss, construction debris, mineral
restriction, or blockage within the internal flow passage.
What confirms correct rainfall spray-face commissioning?
Verify uniform water distribution across the complete 11-3/4-inch
nozzle field without inactive outlets, weak perimeter zones,
pulsing, lateral jetting, or irregular droplet formation. Uneven
coverage normally requires additional flushing or nozzle cleaning.
