Reduced Pressure Zone (RPZ) Assembly Installation in Boulder
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Boulder. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. GFR Plumbing specializes in precise RPZ installation, with proper sizing, placement and testing to meet all regulatory requirements for residential and commercial properties. We work with top brands like Watts and Febco.

Irrigation Backflow Preventer Installation in Boulder
Landscape irrigation is the most common reason homeowners need a backflow device. Fertilizer, herbicides and stagnant water in sprinkler and drip lines can be siphoned into your drinking water if pressure drops. We install pressure vacuum breakers or double check assemblies based on local requirements and the design of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.
Double Check Valve Assembly (DCVA) Installation in Boulder
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Boulder, DCVAs are often installed on fire sprinkler systems or irrigation lines. Our certified plumbers precisely install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.
Pressure Vacuum Breaker (PVB) Installation in Boulder, CO
For low-hazard applications, such as lawn irrigation systems in Boulder, CO, a pressure vacuum breaker, or PVB, is a popular and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also check for proper clearance and drainage.
Double Check Valve Assembly Installation in Boulder
Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules allow. We size them to avoid too much pressure loss on your system.
Commercial Backflow Preventer Installation in Boulder
Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water. We survey the building, identify each cross-connection and install containment and isolation assemblies as required. Work is scheduled after hours or on weekends when needed to avoid shutting down your business. You receive documentation for each device for your records and your water provider.
Understanding Backflow Preventer Installation Costs in Boulder, CO
The cost of backflow preventer installation in Boulder, CO varies with the device type, size, location and complexity of the plumbing changes required. A residential irrigation system and a large commercial water main will be priced very differently. GFR Plumbing provides transparent, upfront quotes after a careful assessment of your property. We aim to offer competitive pricing for high-quality, code-compliant installations that protect your investment and health.
