What Makes This Fresh Water Tank Superior?
NSF Certification for Safety: Unlike generic plastic tanks, this Elkhart Plastics tank is NSF certified for potable water storage, meaning it meets strict standards for food-grade materials that won't leach chemicals or contaminants into your drinking water.
Seamless Durability: The roto-molded construction creates a single, continuous piece with uniform wall thickness and no seams where bacteria, algae, or mold can develop. This ensures your water stays cleaner longer and the tank remains leak-free even under the stress of road vibration.
Temperature Resistant: The food-grade polyethylene construction maintains structural integrity through freeze-thaw cycles and extreme temperatures, preventing cracking that can occur with inferior materials.
Installation & Maintenance
This tank features standard RV fresh water fittings for easy installation. Professional installation is recommended to ensure proper venting, secure mounting, and correct plumbing connections. Regular sanitization with RV-approved cleaners will keep your water fresh and safe for consumption.
Pro Tip: Sanitize your new fresh water tank before first use and periodically throughout the camping season to maintain optimal water quality and prevent bacterial growth.
