Irrigation value boxes are cover devices that provide protection to your sprinkler valves from damage as they prevent dirt and grass from accumulating in the cover and the body of the box.
Sierra Irrigation offers NDS boxes to ensure a longer life for your irrigation system. The boxes are designed with UV deterrents that prevent staining and corrosion to offer years of service under the most demanding outdoor terrain.
At Sierra Irrigation we make sure we only offer the best-quality products to ensure your sprinkler system will be cost-effective, low-maintenance and long-lasting.
