Denver Water is thankful for CDPHE’s work with the State Plumbing Board to ensure unintended consequences from the backflow testing change in HB24-1344 will not occur – giving more time for thoughtful review and discussion. The swift action by the Board protects public health, supports Denver Water’s compliance with drinking water regulations and minimizes the disruption to the people and businesses operating under the prior status quo.

The Colorado State Plumbing Board determined that through April 2025, certified cross-connection control technicians can continue inspecting and repairing backflow prevention devices and will not be subject to discipline if they are not a licensed plumber. This allows the General Assembly the time and ability to fully consider this requirement and hear from stakeholders across the state.

Backflow is the unwanted flow of water or other liquids, mixtures, gasses or substances into the drinking water supply. There are two main ways backflow can occur: Backsiphonage occurs when there is a negative pressure in the water distribution system, which draws the water from a private water system into the public water system. This can occur at any time, such as during a water main break or during a large firefighting effort. Backpressure occurs when the pressure in a private water system exceeds the pressure in the public water distribution lines that can cause normal flow to reverse. A pump used to increase the water pressure within a building’s plumbing system to reach a higher floor might cause this. Click image to see it larger. Click image to see it larger.

A backflow prevention assembly is a mechanical valve arrangement designed to prevent the reversal of the flow of water once it has passed through the valve. Like any mechanical device, a backflow prevention assembly requires maintenance and annual testing. There are different types of backflow prevention assemblies required for different uses and different degrees of hazard. There are no exemptions or grandfathering in of backflow prevention assembly requirements.

Backflow prevention assemblies installed within Denver Water’s distribution system must be approved by the University of Southern California’s Foundation for Cross-Connection Control and Hydraulic Research, otherwise known as being USC-approved. Check with your backflow prevention assembly manufacturer or the product specification sheets to verify that the assembly is USC-approved. You must also confirm the assembly is approved in the orientation for which it is being installed (horizontal, vertical, etc.).

Reduced Pressure Principle Assembly (RP) An RP is required for most commercial, industrial and some multi-family applications. They can also be used on irrigation systems where a pressure vacuum breaker (PVB) cannot be used. Installation requirements: Install a minimum of 12 inches off the floor and 12 inches away from a wall. If the assembly is installed higher than 5 feet off the ground, a platform is required for access and maintenance. Adequate drainage is required, as there is a potential for discharge from the unit. Protect from freezing. Double Check Valve Assembly (DC) A DC is required for fire lines without antifreeze or chemical additives and some residential applications. They are not allowed for irrigation systems. Installation requirements: Install a minimum of 12 inches off the floor and 12 inches away from a wall. If the assembly is installed higher than 5 feet off the ground, a platform is required for access and maintenance. Pressure Vacuum Breaker (PVB) PVBs are for use on irrigation systems. They have specific installation requirements and are limited in their use.  Installation requirements: Must be installed a minimum of 12 inches above the highest point of use and 12 inches away from a wall.
