Fontana Dax Gold Round Rain Shower Head FAQ
1.75 GPM Verification, NPT Joint Sealing & MasterClean Spray Calibration
This Gold round shower head combines a 9.875-inch metal spray face,
single-function 1.75 GPM rainfall delivery, MasterClean easy-service
nozzles, an adjustable swivel joint, and a standard 1/2-inch NPT
connection for wall- or ceiling-arm installations.
How should the 1/2-inch NPT branch be prepared before installing the Gold shower head?
Flush the open shower-arm branch until solder particles, pipe
scale, construction residue, and excess sealing compound are
completely discharged. Inspect the male threads and verify that
the shower arm is rigidly supported before attaching the finished
spray head.
How should the inlet connection be sealed without transferring torque into the swivel joint?
Apply approved thread sealant sparingly and tighten through the
inlet connection rather than rotating the finished spray-face
body. Complete the watertight NPT joint first, then use the swivel
independently to establish the required rainfall angle.
How should the specified 1.75 GPM output be validated during commissioning?
Stabilize the system at normal dynamic pressure, purge trapped
air, and perform a timed volumetric collection test at the outlet.
Low delivery may indicate branch pressure loss, undersized piping,
residual installation debris, mineral buildup, or restriction
within the internal flow passage.
What confirms correct operation across the MasterClean nozzle field?
Confirm uniform rainfall across the complete 9.875-inch spray face
without inactive nozzles, weak perimeter zones, pulsing, or
directional streams. Restricted nozzles should be gently wiped,
followed by additional supply flushing and a complete spray-pattern
retest.
