Double Check Valve Assembly (DCVA) Installation in Dover
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Dover, DCVAs are frequently installed on fire sprinkler systems or irrigation lines. Our certified plumbers carefully 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.
Reduced Pressure Zone Assembly Installation in Dover, DE
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested easily. We carry trusted brands like Watts, Febco, Wilkins and Apollo.

GNV Plumbing works with leading backflow preventer brands known for reliability and durability. We regularly install devices from manufacturers such as Watts, Wilkins by Zurn, Apollo and Conbraco.

We can also advise on models that best fit your budget and application.
Irrigation Backflow Preventer Installation in Dover
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.
Pressure Vacuum Breaker (PVB) Installation in Dover, DE
For low-hazard applications, such as lawn irrigation systems in Dover, DE, 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 expertly install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also make sure of proper clearance and drainage.
Backflow Prevention for Irrigation Systems in Dover, DE
Irrigation systems in Dover, DE are a common source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply.
