The Spears Ball Valve is widely regarded as the "best in class" solution for managing water flow in high-performance irrigation systems. Used by professional farmers and landscape contractors, these valves provide a robust shut-off point that handles pressure with ease. We recommend installing this valve as a main zone control downstream from your irrigation timer to allow for manual system isolation and winterization.
Molded from high-impact PVC in the USA, these irrigation fittings are designed to withstand the rigors of farm and garden use. Unlike standard economy valves, Spears valves feature a full-bore design that virtually eliminates pressure drop, ensuring that your drip irrigation emitters receive consistent water pressure across the entire length of your mainline.

Follow these steps to ensure a leak-free PVC installation.
Step 1: Prep the Pipe
Cut your PVC pipe square. Use a PVC pipe cutter to ensure a clean edge and remove any internal burrs.
Step 2: Clean and Prime
Apply Purple Primer to the outside of the pipe and the inside of the valve socket. This chemical step is critical for a strong solvent weld.
Step 3: Apply Glue
Apply Blue Hot Glue to both surfaces. Insert the pipe into the valve, twisting a quarter turn to spread the cement evenly.
Step 4: Allow to Cure
Hold the fitting in place for 30 seconds to prevent the pipe from "pushing out." Wait at least 15-30 minutes before pressurizing the line.
