Buying Guide
What to consider when choosing a 3-way valve for refrigeration or RO systems:
- Material and safety: Lead-free brass is preferred for potable water and food-grade applications.

- Outlet configuration: Choose 3-way valves with the right outlet arrangement to feed RO, fridge, and dispenser as needed.
- Compatibility: Ensure the valve matches your equipment’s brand/model or is a universal fit for your plumbing setup.
- Installation considerations: Look for valves with easy install features and sealing options (rubber seals, sealing tape).
- Durability: A robust, corrosion-resistant body suits both cold and hot water lines common in residential use.
