Fontana Oil Rubbed Bronze Concealed Shower Mixer Valve FAQ
Inlet Flushing, Service Isolation & Pressure-Balance Commissioning
This oil rubbed bronze wall-mounted shower mixer combines a concealed brass valve,
ceramic temperature regulation, pressure balancing, and integrated hot-and-cold water control.
How should the hot and cold supply lines be prepared before valve connection?
Flush each branch independently to remove pipe scale, solder residue, sealing compound, and construction debris that could restrict the ceramic cartridge or concealed inlet passages.
What should be verified before the concealed wall is permanently closed?
Pressure-test the brass valve body and all G1/2-inch joints, confirm correct inlet orientation, inspect for leakage, and verify unrestricted handle and cartridge movement before waterproofing and tiling.
How should pressure-balancing performance be tested during commissioning?
Operate the shower while nearby fixtures are cycled, confirming that the regulating cartridge limits sustained outlet-temperature movement during hot- or cold-side pressure fluctuations.
Why must the integral service stops remain accessible?
Accessible inlet stops permit isolated cartridge flushing, temperature-limit adjustment, inspection, and component replacement without shutting down water service to the complete plumbing zone.
