Protect Your Irrigation Pipelines

Corrosion of standard galvanized pipe can occur, especially when growers use less desirable water sources, such as wastewater, process water, and even corrosive water; and when producers add crop protection chemicals or soil amendment products to their irrigation water.

Valley PolySpan irrigation poly pipes protect your irrigation pipelines from any corrosive components in your water, ensuring a long life for your machine. Repiping is the most economical way to significantly extend the life of your machine.
