The CDF DTV Heavy Drain Tempering Valve Kit is designed to automatically mix cold water with hot wastewater before it enters the drain system. This prevents damage to plumbing caused by extremely high water temperatures and ensures compliance with plumbing codes that limit drain line temperatures.

This model features a 1-inch water inlet connection, which is suitable for a variety of commercial dish machines, combi ovens, and other high-temperature appliances that release hot effluent into floor drains or grease traps.

Many commercial dishwashers and steam equipment discharge water at temperatures well above what drain lines and PVC piping can handle. A drain tempering valve automatically reduces that temperature by mixing in cold water, protecting your infrastructure and helping you comply with local plumbing codes.

The tempering valve is thermostatically controlled. When hot water discharge reaches a certain threshold, the valve opens to allow cold water to blend in. This maintains a safe discharge temperature without manual intervention or wasted water.

Yes, as long as your appliance produces high-temperature wastewater and uses a 1-inch drain line connection, this kit is a compatible and recommended solution. It’s especially important for units discharging into PVC drain lines or floor sinks.

Yes, the DTV kit is designed to help your facility meet uniform plumbing code (UPC) and mechanical code requirements, many of which specify maximum drain discharge temperatures, often around 140°F.

Yes, for proper functionality and code compliance, the drain tempering valve kit should be installed by a licensed plumber or facility technician experienced with high-temperature commercial appliances and drainage systems.

It’s commonly installed in restaurants, hospitals, hotels, schools, commissaries, and other institutional kitchens where high-volume hot water discharge is part of daily operations.
