Irrigation Backflow Preventer Installation in Norwalk
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.
Double Check Valve Assembly Installation in Norwalk
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.
Double Check Valve Assembly (DCVA) Installation in Norwalk
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 Norwalk, DCVAs are frequently 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.
Residential Backflow Preventer Installation in Norwalk
For homeowners in Norwalk, protecting your family's drinking water is the top priority. We install many types of backflow preventers, often required for irrigation systems, fire suppression lines or properties with alternative water sources. Our plumbers will assess your home's plumbing layout to recommend the right device, meeting local health department regulations and protecting your potable water supply. We handle everything from small residential devices to bigger systems.
Pressure Vacuum Breaker (PVB) Installation in Norwalk, CT
For low-hazard applications, such as lawn irrigation systems in Norwalk, CT, 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.
Backflow Enclosures and Freeze Protection in Norwalk, CT
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Frozen pipes are a regular 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.

Residential pressure vacuum breakers usually cost $250 to $700 installed. Double check and RPZ assemblies for larger homes or businesses range from $800 to $3,500 or more depending on size and enclosure needs.
Backflow preventers are installed at cross-connection points where non-potable water could enter the potable water supply. Common locations include irrigation system connections, fire sprinkler lines, boiler systems and connections to auxiliary water supplies, usually just after the main water meter or at the point of hazard.
Yes, in many areas a permit is required for backflow preventer installation, especially for systems connected to the municipal water supply. GLV Plumbing will help you navigate the permitting process in Norwalk and make sure all required inspections are scheduled and passed.
In Norwalk, most backflow preventers must be tested annually by a certified backflow tester to confirm they are working correctly and providing adequate protection. This is a separate service from installation but is crucial for ongoing compliance and safety.
It depends on the hazard and local rules. Irrigation often uses a PVB or double check, while high hazard connections like commercial kitchens or chemical injection require an RPZ.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are typical signs. Visible corrosion or a cracked body from freezing also means service is needed.
