Irrigation Backflow Preventer Installation in Decatur
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 layout of your system. Above-ground installs are set at least 12 inches above the highest sprinkler head when a PVB is used.

Reduced Pressure Zone (RPZ) Device Installation in Decatur, IL
For high-hazard applications in Decatur, IL where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is usually required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. HVM Plumbing specializes in RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is essential for effective operation.
Double Check Valve Assembly (DCVA) Installation in Decatur
The double check valve assembly, or DCVA, is a common backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Decatur, 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.
Commercial Backflow Preventer Installation in Decatur
Restaurants, salons, dental offices and light industrial buildings often need multiple backflow devices on soda machines, boilers, dishwashers and process water.

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 utility.
Backflow Testing and Certification in Decatur
Most water providers require testable backflow assemblies to be certified at installation and then annually. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.
