Fontana Bolln Chrome Single Function Universal Rain Round Shower Head FAQ
Supply-Arm Reinforcement, 2.5 GPM Verification; Chrome Finish Protection
The Fontana Bolln Chrome universal rain shower head combines an 11-3/4-inch metal spray face, single-function rainfall delivery, a rated 2.5 GPM flow rate, an adjustable swivel inlet, and compatibility with standard U.S. shower plumbing connections.
How should the concealed shower-arm connection be reinforced for this large-format head?
Secure the drop-ear fitting to structural blocking before installing the shower arm. The 11-3/4-inch metal head creates greater leverage than a compact fixture, so the arm must remain rigid without rotation, deflection, or lateral movement at the finished wall.
How can the specified 2.5 GPM discharge be verified during commissioning?
Operate the shower at normal dynamic pressure, allow the spray to stabilize, and collect the discharge for a measured interval. Convert the captured volume to gallons per minute and investigate upstream restriction if the measured flow is materially below 2.5 GPM.
What causes weak discharge around the outer perimeter of the spray face?
Residual construction debris, trapped air, insufficient dynamic pressure, mineral accumulation, or a partially restricted shower valve can reduce pressure within the outer distribution channels. Flush the branch and clean affected nozzles before modifying any internal flow component.
How should the Chrome surface be cleaned without damaging its reflective plating?
Rinse away soap residue and dry the shower head with a soft microfiber cloth. Use only a diluted pH-neutral cleaner and avoid abrasive pads, acidic descalers, bleach, ammonia, steel wool, or polishing powders that may scratch or haze the chrome surface.
