With its finely tuned ceramic operating cartridge, the new Chicago Faucets pressure-balancing shower valve offers improved flow management, precise hot- and cold-water mixing, simplified hot water volume adjustment, and a reduced flow rate (GPM) for both tub and shower service. Hot and cold supply inlet check stops are built into every valve. The complete fittings feature modern wall trim styling, with a polished chrome wall plate that's dual-indexed, allowing the user to adjust temperature quickly and easily.
