Reduced Pressure Principle Assembly (RP) An RP is required for most commercial, industrial and irrigation domestic water applications. Installation requirements:

Backflow and Cross-Connection Requirements The Colorado Department of Public Health and Environment regulates drinking water quality and standards. The Colorado Primary Drinking Water Regulations (Section 11.39) outline Utilities' requirements for backflow prevention and cross-connection control. In addition to installing an assembly, the water customer must have the assembly tested upon installation and annually thereafter by a certified tester. It’s important to remember that testing of existing and replacement backflow assemblies must be reported to BSI Online, and testing of new installation backflow assemblies should be submitted to Fort Collins Utilities by emailing cross-connection@fcgov.com or mailing to: Fort Collins Utilities Attn: Norm Mill Cross-Connection Control PO Box 580 Fort Collins, CO 80522

Backflow prevention device

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.

If an unprotected cross-connection is discovered on the property, Fort Collins Utilities will require you to install an approved backflow prevention assembly within 60 days of the survey. We realize that, in some cases, a longer period of time may be required for larger installations. Please email the Cross-Connection Control office at cross-connection@fcgov.com or call 970-416-2249 for approval of any extended periods of time. It is the customer's responsibility to hire a licensed installer to install a backflow prevention assembly. Upon installation, testing is required to be completed by a certified ABPA (American Backflow Prevention Association) or ASSE (American Society of Sanitary Engineering) tester within 48 hours of installation and send the test report(s) to Fort Collins Utilities. The backflow prevention assembly is required thereafter to be tested annually by a certified backflow prevention assembly tester. It is at the sole discretion of Fort Collins Utilities Cross-Connection Control office to suspend water service if the premise poses a health risk to the public water supply, when a backflow prevention assembly has not been installed or tested. If you did not pass inspection or have other questions, please call 970-416-2249.

What is Backflow? Backflow happens when the normal flow of water is reversed from its intended direction in any pipeline or plumbing system. The danger of backflow comes with the potential for cross-contamination, which is when water that has contacted chemicals or hazardous compounds flows back into the drinking water system.

Cross-connections are actual or potential connections between the public water supply and any other system that could accidentally introduce a contaminant back into the public water supply. According to the Environmental Protection Agency, cross-connections can be a serious public health hazard, if they do not have adequate backflow prevention assemblies installed. There are numerous, well-documented cases in which cross-connections have been responsible for contamination of drinking water that, when consumed, caused the spread of sickness or disease.

What is backflow in plumbing

Backflow prevention assemblies installed within Utilities’ 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-up, vertical-down, etc.).

Residential Properties Requirements for multi- and single-family residences are assessed based on site hazards. Single-family residential properties are encouraged to hire a certified backflow prevention assembly tester to test their irrigation system every three years. For homeowners, the most common types of cross-connections include hoses connected at hose bibs, in-ground irrigation systems, private fire sprinkler systems, boiler systems, and pool or pond equipment. The most common residential backflow device is a PVB, or Pressure Vacuum Breaker.

Fort Collins Utilities is a community-owned utility that manages four essential services – Light & Power, Water, Wastewater and Stormwater.

Fort Collins Utilities’ Backflow Prevention and Cross-Connection Control Program protects the public water supply from pollutants and contaminants that could, under certain circumstances, be drawn into the public water supply from private properties. State law requires that a backflow device be installed on any water system that is connected to the drinking water system and carries the potential for cross-contamination.

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:

Commercial, Industrial, Domestic, Irrigation and Fire Lines All commercial, industrial, domestic, irrigation and fire line services are required to have an approved backflow prevention assembly installed and tested annually.

Auxiliary Water Supply or Dual Water Lines All customers with an auxiliary water supply or dual water lines, such as a well or pond, also are required to install and maintain backflow prevention assemblies.

Per the Colorado Primary Drinking Water Regulations (Section 11.39), Fort Collins Utilities is required to survey water services for potentially hazardous cross-connections, where water could flow from a property into the public water system and compromise the water quality for other customers. Surveys are completed on:

Stop before you do anything with your home heating or cooling, or specifically geothermal or with heat pumps, talk to these guys. We've had a very complicated geothermal heating system, multiple heat exchangers, underfloor heating, pumps and also water cooled AC. Jimmy and the team were the only ones who knew absolutely everything that needed to be done to get it working properly, efficiently. Not only that they explained everything along the way and made sure the system and us as the users were operating it and it was properly setup. My only wish is that we'd engaged Radian Heating and Cooling earlier in the process it would have saved so much time and effort. These guys solved lots of problems others couldn't and set the system up much better and with more reliability. They are always ready to answer a quick question and very responsive. I rarely write reviews but these guys really deserve the review and you'll be very happy you engaged them. Thanks Jimmy and team !

When we moved into our house last year, just as winter was setting in, we realised we needed to retrofit 2x 30yr old gas boilers for our underfloor heating system. After trying to get quotes, install times from other vendors, Radiant were able to come out on short notice and inspect our system / requirements. Sizing the system was quite complex given the type of piping used in original build, the layout of our house, expected usage of each section and the potential heat loss from single pane windows. Within a few weeks, Radiant were on on site installing 2x new electric heat pumps including the relocation of DHW units / buffer tanks to make better use of our internal space. Once installed, our house was nice and warm throughout the depths of a Southern Highlands winter and the efficiency of the unit was much better, and I continue to gain efficiencies through minor adjustments (timer settings, buffer tank temperatures etc) which I discuss with the Radiant team. Been a pleasure to work with Jimmy and Josh
