Pressure Vacuum Breaker (PVB) Installation in Norwich, CT
For low-hazard applications, such as lawn irrigation systems in Norwich, CT, 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 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 Prevention in Norwich, CT
Commercial properties in Norwich, CT often have complex plumbing systems that pose a higher risk of cross-contamination and require robust backflow prevention. Restaurants, hospitals, industrial facilities and even multi-family buildings must comply with commercial plumbing codes. GLV Plumbing provides full installation of heavy-duty backflow preventers, including large diameter RPZ assemblies, to safeguard public health and meet Connecticut regulations for businesses. We handle all required permits and inspections.
Backflow Preventer Installation Cost Comparison in Norwich, CT
A residential pressure vacuum breaker is the most affordable option, while larger RPZ assemblies for commercial buildings cost significantly more in parts and labor. Size, brand, enclosure needs and how much existing pipe must be modified all affect the price. Replacing a failed old device with a new one is often cheaper than repeated rebuilds. We give you an itemized quote that includes the initial certification test.

Backflow Enclosures and Freeze Protection in Norwich, CT
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Frozen pipes are a real winter risk in Connecticut, especially lines in exterior walls, crawlspaces, and unheated porches or garages. 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.
