✓ Premium FDA-Approved Material
Made from high-quality, durable polyethylene that's fully approved for safe drinking water storage. This food-grade material is better than many stock tanks installed in factory-built RVs, ensuring your water stays fresh and safe for consumption.
✓ Seamless One-Piece Roto-Molded Construction
Elkhart Plastics uses an advanced roto-molding process where high-density plastic is rotated and molded into shape. This creates a seamless tank with walls of equal thickness throughout—no weak spots, no seams, no joints. The result is superior strength and leak-proof reliability that outlasts and outperforms typical OEM tanks.

Designed to stay clean and functional even after years of use. The non-porous polyethylene surface resists staining and won't corrode or rust like metal tanks, ensuring your water stays fresh and your tank stays dependable season after season.
