Protecting restroom users from scalding is critical in commercial applications. Though thermostatic mixing valves (TMVs) are a common way to regulate water temperature, they can add undue time and costs to one’s project. Historically, these valves were separate from the faucet, representing an additional component that needed to be specified, installed and maintained. From a practical standpoint, servicing the mixing valve is more difficult when it is located below the deck.
Plumbing engineers can now streamline restroom design and maintenance by selecting a faucet with a built-in thermostatic hot water temperature limiter. When the temperature limiter is incorporated directly into the faucet spout, the need for a separate TMV below-deck is eliminated.
