Point of Use

Lawler under-the-counter valves are designed exclusively to help you achieve safe, precise water temperature control at the point-of-use. All Lawler under-the-counter valves protect against scalding and chilling, are easy to install, and are backed by Lawler’s One Year Warranty. Use Lawler under-the-counter point-of-use valves when you need a “final layer” of safety for users of electronic faucets, hand lavs, as well as sensor and metering faucets.

Shower knob
