The Flash™ Universal Shower Rough-In Valve is designed to simplify plumbing installations with unmatched versatility and durability. Engineered for seamless integration into various bathroom setups, this valve features a robust cast brass body that withstands prolonged water exposure while maintaining reliability over time. Its universal inlets/outlets accommodate 1/2″ copper, iron pipe, or PEX adapters without additional fittings, reducing potential leak points and streamlining installation.
A standout feature is its back-to-back capability, allowing quick reversal of hot and cold lines during setup—ideal for retrofit projects or last-minute design changes. The included stainless steel retaining ring secures the test plug or cartridge effortlessly, eliminating screws and simplifying maintenance. A built-in plaster guard protects the valve during installation while serving as a mounting guide for thin-wall applications.
For plumbers and DIYers alike, this valve offers unmatched convenience: screwdriver stops enable easy servicing without disassembling trim, while a flat-back design ensures snug mounting against cross braces. With a wide rough-in range (1-3/4″ to 2-3/4″ from wall), it adapts to diverse wall depths without compromising stability.
The Flash™ valve also includes a test plug that allows pressure testing (up to 300 psi) before cartridge installation, saving time and avoiding costly rework. Its exclusive Plaster Guard doubles as structural support during thin-wall installations. With a generous 5.1 gpm flow rate at 45 psi*, it delivers strong water pressure for satisfying showers while minimizing energy waste.
Whether upgrading an existing bathroom or building new, this valve’s universal adaptability, durable construction, and user-friendly design make it a top choice for hassle-free shower system installations.
