Why Choose Elkhart Plastics Fresh Water Tanks?
Elkhart Plastics has earned its reputation as the industry leader in RV water tank manufacturing. Every tank is engineered to meet or exceed strict quality and health safety standards, ensuring your drinking water stays pure and protected.
✓ FDA-Approved Food-Grade Material
Manufactured from premium high-density polyethylene that's fully FDA-approved for potable water storage. Unlike cheaper alternatives, this material contains fewer impurities and is specifically designed for safe drinking water - often superior to factory-installed tanks in many RVs.
✓ Seamless Rotational Molding Process
Elkhart Plastics uses advanced roto-molding technology where high-density plastic is rotated and molded into a single, seamless piece. This creates uniform wall thickness throughout the entire tank with no weak spots, seams, or joints that could fail over time.
✓ Built to Last - Superior Durability
Engineered to withstand the bumps, vibrations, and temperature changes of life on the road. The seamless construction and thick walls (0.180") provide exceptional impact resistance and leak-proof reliability that outlasts typical OEM tanks.
✓ Stain, Corrosion & Rust Resistant
The polyethylene construction naturally resists staining, corrosion, and rust. Your tank will stay clean and functional even after years of use, keeping your water fresh and your system dependable.
