Fontana Dax Brushed Nickel Round Rain Shower Head FAQ
1.75 GPM Testing, NPT Joint Sealing & MasterClean Spray Balancing
This brushed nickel 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 shower branch be prepared before connecting the 1/2-inch NPT inlet?
Flush the open shower-arm branch until pipe scale, solder residue,
construction sediment, and excess thread sealant are fully removed.
Inspect the male threads for damage and confirm that the shower arm
is mechanically secure before attaching the finished fixture.
How should the threaded joint be sealed without marking the brushed nickel finish?
Apply approved thread-sealing material sparingly to the male NPT
connection and tighten through the inlet fitting rather than the
finished spray-face body. Use protected tools and avoid transferring
rotational torque through the swivel assembly.
How should the specified 1.75 GPM flow rate be verified during commissioning?
Stabilize the system at normal dynamic pressure, purge trapped air,
and conduct a timed volumetric collection test. Reduced discharge
may indicate upstream pressure loss, an undersized branch, residual
debris, mineral restriction, or obstruction at the inlet passage.
What confirms balanced operation of the MasterClean spray face?
Confirm consistent rainfall discharge across the entire 9.875-inch
nozzle field without inactive outlets, weak perimeter zones,
pulsing, or directional jetting. Individual restricted nozzles
should be gently wiped and retested after additional flushing.
