Backflow Prevention for Irrigation Systems in West Haven, CT
Irrigation systems in West Haven, CT are a frequent source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply. Installing a dedicated backflow preventer for your sprinkler system is often a local code requirement. We specialize in selecting and installing the correct device, such as a pressure vacuum breaker or atmospheric vacuum breaker, to protect your home's main water line from contaminants introduced by your landscape irrigation.

Double Check Valve Assembly Installation in West Haven
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.

Frequently Asked Questions About Backflow Preventer Installation in West Haven
The cost for backflow preventer installation in West Haven, CT typically ranges from $400 to $1,500, depending on the type of device, its size and the complexity of the installation. A basic residential PVB for an irrigation system is generally on the lower end, while a commercial-grade RPZ assembly costs more because of material and labor requirements.
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 work through the permitting process in West Haven and make sure all required inspections are scheduled and passed.
We install backflow preventers from leading manufacturers known for quality and reliability. Our preferred brands include Watts, Febco, Zurn and Apollo, so you receive a durable, effective device that meets all industry standards.
An RPZ, or reduced pressure zone device, provides the highest level of protection and is used for high-hazard applications where contaminants could be toxic. A DCVA, or double check valve assembly, is used for low-hazard applications where contaminants are non-toxic. The choice depends on the risk of contamination at the cross-connection point.
Most manufacturers offer one to five year warranties depending on the model. We also warranty our installation labor and will review the coverage with you.
Signs of a failing backflow preventer include discolored or foul-smelling water, a noticeable drop in water pressure, visible leaks around the device or water discharging from the relief valve on an RPZ. If you notice any of these, contact us for an inspection in West Haven.
Most residential installs take two to four hours including testing. Large commercial assemblies can take a full day, particularly if piping must be reconfigured.
We install Watts, Febco, Wilkins by Zurn and Apollo assemblies. Each has readily available repair kits, which keeps future service affordable.
