Fontana Lyon Polished Gold Wall-Mounted Shower Head FAQ
2.5 GPM Verification, Threaded-Inlet Testing & Rainfall Spray Commissioning
This polished gold square wall-mounted shower head combines
corrosion-resistant stainless-steel construction, a 7-11/16-inch
rainfall spray face, a single-function 2.5 GPM discharge, and a
standard 1/2-inch threaded connection for modern shower installations.
How should the shower supply branch be flushed before installation?
Remove the finished shower head and flush the wall branch until
solder residue, pipe scale, construction debris, and excess
thread-sealing compound are fully discharged. Inspect the
1/2-inch threaded outlet before connecting the finished fixture.
How should the threaded inlet be sealed and hydraulically tested?
Inspect both mating threads, apply approved sealing material
sparingly, and engage the 1/2-inch connection without
cross-threading. Support the inlet during tightening, pressurize
the branch, and inspect the completed joint for seepage.
How should the specified 2.5 GPM discharge be field-verified?
Stabilize the operating 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 7-11/16-inch
spray field without inactive outlets, weak perimeter zones,
pulsing, lateral jetting, or irregular droplet formation. Uneven
coverage normally requires branch flushing or nozzle cleaning.
