Fontana Lyon Chrome Wide Rain Shower Head FAQ
2.5 GPM Verification, Threaded-Joint Testing & Spray-Field Balancing
This chrome square wall-mounted rain 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 wall supply be flushed before installing the finished shower head?
Remove the finished head and flush the shower branch until pipe
scale, solder residue, construction debris, and excess sealing
compound are fully discharged. Inspect the 1/2-inch outlet threads
and confirm unobstructed flow before final assembly.
How should the shower arm and threaded inlet be pressure-tested?
Apply approved thread sealant sparingly, engage the 1/2-inch
connection without cross-threading, and tighten while supporting
the inlet body. Pressurize the branch and inspect the completed
joint for seepage before closing access or completing finishes.
How should the specified 2.5 GPM discharge be verified during commissioning?
Stabilize the supply pressure, purge entrained air, and perform a
timed volumetric test at the shower head. Low measured output may
indicate branch pressure loss, construction debris, mineral
restriction, or obstruction within the flow-control passage.
What confirms balanced operation across the square rainfall spray face?
Verify uniform discharge across the full 7-11/16-inch nozzle field
without inactive outlets, weak edge zones, pulsing, lateral
jetting, or irregular droplet formation. Uneven coverage normally
requires branch flushing or localized nozzle cleaning.
