The CDF DTV15 is a drain tempering valve kit designed to automatically blend cold water with hot effluent before it enters the drainage system. It protects plumbing lines from thermal damage and helps ensure compliance with plumbing codes that regulate maximum discharge temperatures.

This unit features a 3/4-inch cold water inlet, making it ideal for smaller equipment or lower-volume applications that still produce high-temperature wastewater, such as compact dishwashers, undercounter units, or combi ovens.

High-temperature water discharged from commercial equipment can damage PVC drain lines or cause premature wear to other plumbing components. The DTV15 reduces water temperature at the drain, helping extend pipe life and meet code requirements that typically limit discharge to 140°F or lower.

This thermostatic valve automatically senses the temperature of the discharged water. When it exceeds the set threshold, the valve opens to allow cold water to mix in, maintaining a safe and consistent temperature entering the drain system.

The CDF DTV15 is designed for use with any commercial equipment that discharges hot water, such as dish machines, steamers, or combi ovens, especially those where a 3/4-inch connection is appropriate.

Yes, the DTV15 is designed to support compliance with plumbing and mechanical codes, including UPC guidelines on maximum drain discharge temperatures, which helps avoid costly code violations during inspections.

Yes, the drain tempering valve should be installed by a qualified plumber or facility technician to ensure proper function, correct cold water supply pressure, and integration with your existing drainage setup.

This unit is ideal for use in restaurants, cafeterias, hotels, commercial kitchens, hospitals, and institutional foodservice settings where equipment releases hot wastewater into floor drains or grease traps.
