Fontana Bolln Brushed Gold Round Rain Shower Head FAQ
2.5 GPM Validation, Supply-Arm Support & Round Spray-Field Commissioning
This brushed gold round rain shower head combines durable metal
construction, an 11-3/4-inch spray face, single-function rainfall
delivery, and a specified 2.5 GPM flow rate for residential and
commercial shower installations.
How should the shower supply branch be flushed before installing the head?
Remove the finished shower head and flush the open supply arm until
pipe scale, solder residue, construction debris, and excess sealing
compound are fully discharged. Inspect the threaded connection
before installing the finished fixture.
What support is required for the separately specified shower arm?
Secure the concealed drop-ear fitting to structural blocking so the
arm cannot rotate or deflect under the weight of the 11-3/4-inch
head. Confirm that the arm projects level and transfers no lateral
load into the shower-head inlet.
How should the specified 2.5 GPM flow rate be field-verified?
Stabilize the operating pressure, purge entrained air, and perform
a timed volumetric collection test at the shower head. A reduced
result can indicate branch-line pressure loss, debris restriction,
mineral accumulation, or an obstructed internal flow passage.
What confirms correct commissioning of the round rainfall spray field?
Verify consistent discharge across the complete 11-3/4-inch face
without inactive nozzles, weak perimeter coverage, pulsing,
sideward jetting, or irregular droplet formation. Uneven delivery
normally requires additional flushing or nozzle cleaning.
