Fontana Dax Polished Chrome Round Rain Shower Head FAQ
Flow Restriction Control, Ball-Joint Loading; Chrome Surface Protection
The Fontana Dax Polished Chrome round rain shower head combines a 9.875-inch metal spray face, angled MasterClean nozzles, single-function 1.75 GPM rainfall delivery, and an adjustable ball-joint swivel with a standard 1/2-inch NPT connection.
How should the supply line be flushed before the shower head is connected?
Open the shower valve with the head removed and flush the 1/2-inch supply until solder residue, thread sealant, pipe scale, and construction debris are fully cleared, preventing blockage of the internal flow-control passage and individual spray outlets.
What can cause reduced output from the 1.75 GPM spray system?
Low dynamic pressure, debris within the inlet, mineral restriction at the MasterClean nozzles, or an obstructed upstream valve can reduce discharge. Verify branch pressure and clean the spray face before altering any flow-control component.
Why should the ball joint not be used to tighten the threaded connection?
Applying installation torque through the adjustable joint can overload its internal seal and bearing surfaces. Tighten only at the designated inlet connection, then use the ball joint solely for final spray-angle positioning.
How should water spotting be controlled on the Polished Chrome finish?
Dry the exposed surface after use with a soft microfiber cloth and remove residue using a neutral, nonabrasive cleaner. Avoid acidic descalers, chlorine compounds, steel wool, and polishing powders that may scratch or haze the reflective chrome surface.
