High-traffic restrooms need consistent, safe water temperature—especially in schools, offices, hospitals, and venues. Thermostatic Mixing Valves (TMVs) blend hot and cold water to a stable set point and shut down rapidly if hot or cold supply fails, helping prevent scalds while improving user comfort.
What a TMV Does
A TMV constantly balances hot and cold inputs to deliver a target temperature (e.g., 100–110°F at lavatories). When supply conditions change, the valve self-corrects. If hot or cold fails, it limits flow to help protect users.
Benefits for Facilities
- Safety: Reduces scald risk and supports safer, ADA-friendly use.
- User experience: Steady temperature—no more “too hot / too cold” complaints.
- Efficiency: Fewer manual adjustments and fewer temperature-related service calls.
- Compliance: Helps meet many local codes and best practices (always verify your jurisdiction).
Good, Better, Best: Where to Install
- Point-of-use (at each sink): Maximum control where users interact.
- Branch/fixture group: One valve serving multiple lavs for simplified upkeep.
- Central plant + local trim: A building mixer plus local TMVs where precision is critical.

Quick Technician Checklist
- Confirm minimum flow/pressure and hot-water supply temperature.
- Set the outlet temperature (typ. 100–110°F for public lavs) and record it.
- Test fail-safe: simulate hot/cold loss and verify reduced/blocked flow.
- Schedule periodic cleaning of checks/screens; re-verify temperature.
