Rely on the Behlen Country 2-Hole Energy-Free HydroStation MAX to deliver fresh, clean water to your livestock all year—no electricity required. With its heavy-walled poly construction and extra-thick lid, this waterer stands up to livestock pressure and the harshest elements while minimizing maintenance. It features an industry-exclusive self-cleaning valve body that resists hard water deposits and calcium buildup, and a non-siphoning automatic valve to prevent backflow. Designed for use with pressure lines between 25-55 psi (regulators needed outside that range), its ultra-thick urethane insulation and optional Poly Earth Tube help maintain temperatures year-round even during winter and summer extremes. Smooth, curved edges, stainless steel hardware, a removable lid and drain plug make cleaning easy, and built-in hold-downs keep it securely in place. Dimensioned at approx 36″ L × 21″ W × 23″ H, weighing ~ 83-86 lbs, it’s a reliable, durable choice for two-animal opening applications.
