Why Choose Elkhart Plastics Holding Tanks?
Rotomolded Excellence: Unlike cheaper welded tanks, Elkhart Plastics uses advanced rotational molding technology to create seamless, one-piece tanks with uniform wall thickness throughout. This eliminates weak spots, seams, and potential failure points that plague inferior tanks.
Superior Strength & Durability: The 0.180" thick walls are engineered to withstand the constant vibration, road shock, and temperature extremes your RV experiences. High-density polyethylene construction resists cracking, warping, and UV degradation for years of reliable service.
Health & Safety Certified: Manufactured to meet strict quality and health safety standards with fewer impurities than competitor tanks. Safe for both black water (sewage) and gray water (sink/shower) applications.
