Reduced Pressure Zone (RPZ) Device Installation in Rochester, NH
For high-hazard applications in Rochester, NH 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.

Proper installation is critical for effective operation.

Emergency Backflow Preventer Replacement in Rochester

Backflow Enclosures and Freeze Protection in Rochester, NH
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Pipes in exterior walls, crawlspaces, camps and vacation properties are especially likely to freeze when the heat is turned down. We install insulated enclosures, freeze blankets or heated cabinets based on your local climate. 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.
Pressure Vacuum Breaker (PVB) Installation in Rochester, NH
For low-hazard applications, such as lawn irrigation systems in Rochester, NH, 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 carefully install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also check for proper clearance and drainage.
Commercial Backflow Preventer Installation in Rochester
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 keep from shutting down your business. You receive documentation for each device for your records and your water provider.

Most municipalities require annual testing of backflow preventers by a licensed, certified backflow tester. This verifies the device is working correctly and continues to protect your potable water supply from contamination. We can also help with scheduling these annual tests.
Backflow is when water flows the wrong way through a pipe and carries contaminants into the clean water supply. It can happen from back siphonage during a pressure drop or back pressure from pumps and boilers.
Most water providers require testable assemblies to be tested at installation and then annually. Some high hazard facilities may be tested more often.
