The Door Bull R22000-WS Universal Valve
R22000-WS combines durability with a universal trim approach and an integrated diverter. Its back-to-back installation capability makes it a robust option for new construction and retrofits alike. The forged brass construction offers corrosion resistance and long-lasting performance, while compatibility with standard trim kits helps simplify the selection process for multi-brand projects.

Buying Guide
- Compatibility: Look for universal or broad trim-kit compatibility to minimize wall repair when upgrading fixtures. MultiChoice and universal options typically cover a wide range of trim brands and series.
- Diverter Options: If you plan to use diverter features (3-way or 6-way), choose a valve with an integrated diverter or strong compatibility with common diverter kits. Consider whether you need a separate diverter valve or a valve with an integrated diverter.
- Back-to-Back Installation: For retrofit projects or certain layouts, back-to-back installation capability reduces wall disruption and eases alignment during installation.
- Materials and Durability: Brass bodies offer long-lasting durability and corrosion resistance, especially in hard water areas. Solid brass or forged brass construction is a plus for longevity.
- Inlets and Connections: Ensure the valve supports your preferred piping: copper, PEX, CPVC, or iron. Universal inlets reduce adaptation steps and leak points.
- Serviceability: Stops and removable cartridges aid future maintenance. Screwdriver stops can simplify installation and future servicing inside the wall.
- Warranty and Support: Valves backed by lifetime or extended warranties indicate manufacturer confidence and provide long-term assurance during home ownership.
- Installation Context: For new construction, standard-inlet valves are common. For retrofits, prioritize valves that minimize wall repair and are compatible with existing trim kits.
