Fontana Dax Oil Rubbed Bronze Round Rain Shower Head FAQ
Dynamic-Pressure Testing, Swivel Joint Loading & MasterClean Nozzle Service
This Oil Rubbed Bronze 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 flushed before the Oil Rubbed Bronze head is installed?
Leave the 1/2-inch NPT shower arm open and run the supply until
solder particles, pipe scale, thread-sealant residue, and other
construction debris are fully discharged. Debris remaining in the
branch can restrict the internal flow passage and create uneven
rainfall across the spray face.
How should the threaded connection be tightened without loading the swivel assembly?
Apply approved thread sealant sparingly and tighten through the
inlet connection rather than rotating the finished shower-head
body. Complete the watertight NPT joint first, then reposition the
spray face through the swivel so installation torque is not
transferred into the adjustable joint.
How should the specified 1.75 GPM rainfall output be tested under operating conditions?
Stabilize the system at normal dynamic pressure, purge trapped air,
and collect the outlet discharge for a measured time interval.
Reduced flow may indicate supply-line pressure loss, undersized
branch piping, residual installation debris, mineral loading, or
restriction within the shower-head flow passage.
What confirms correct commissioning of the 9.875-inch MasterClean spray field?
Verify uniform rainfall from the center and perimeter nozzles
without inactive outlets, concentrated streams, pulsing, or weak
outer zones. Restricted MasterClean nozzles should be gently
wiped, followed by additional branch flushing and a complete
spray-pattern retest.
