Backflow Enclosures and Freeze Protection in Havre, MT

Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Winterizing unused buildings, draining outdoor faucets and keeping heat on prevent the most common freeze damage. We install insulated enclosures, freeze blankets or heated cabinets based on your location. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and service.

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 Havre, MT

For high-hazard applications in Havre, MT where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is often required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. DFV Plumbing is experienced with 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.

Pressure Vacuum Breaker (PVB) Installation in Havre, MT

For low-hazard applications, such as lawn irrigation systems in Havre, MT, a pressure vacuum breaker, or PVB, is a common 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.

Backflow Prevention for Irrigation Systems in Havre, MT

Irrigation systems in Havre, MT are a common source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply.

Navigating the plumbing codes for backflow prevention in Havre, MT can be challenging. DFV Plumbing stays up to date with local and state regulations so every installation is fully compliant. Water heater replacements, new fixtures and water or sewer line work generally need a permit and inspection. From proper device selection and placement to required permits and inspections, we handle every part of code compliance. Your system works as intended and avoids fines or costly rework down the line.

Double Check Valve Assembly Installation in Havre

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 permit. We size them to avoid excessive pressure loss on your system.
