Effortless Installation

white fittingOur camper fresh water tanks are designed for easy integration into your plumbing system, thanks to the inclusion of female NPT openings and spin-weld fittings. Experience the unrivaled strength and durability of our tailor-made tanks, ensuring a hassle-free installation process. With a seamless, one-piece roto-molded construction, our tanks eliminate the presence of seams, reducing the risk of leaks or cracks. Rest assured, our tanks are built to withstand the test of time, providing you with a robust and leak-free solution.




The Seamless Tank Difference?

Overall, seamless tanks are considered best because they provide superior durability, leak resistance, hygiene, and ease of maintenance compared to tanks with seams. It offers a more reliable and long-lasting solution for storing liquids, such as water, in various applications, including RVs, boats, and other vessels.

    rotomolding process graphic
  1. Enhanced Durability: A seamless tank, typically manufactured through a roto-molding process, eliminates the need for seams or joints. This design feature ensures that there are no weak points where leaks or cracks could occur over time. As a result, the tank is more durable and less prone to structural failures.
  2. Leak Prevention: The absence of seams greatly reduces the risk of leaks. With traditional tanks that have seams, there is always a possibility of those seams deteriorating or becoming compromised over time, potentially leading to leaks and water damage. A seamless tank eliminates this concern and provides added peace of mind.
  3. Improved Hygiene: Seams in a tank can create crevices or hard-to-reach areas where bacteria, mold, or other contaminants can accumulate. A seamless tank eliminates these potential breeding grounds for pathogens, making it easier to clean and maintain proper hygiene standards.
  4. Easy Cleaning and Maintenance: Without seams, a seamless tank offers a smooth and uniform interior surface. This facilitates easier cleaning and maintenance since there are no crevices or corners where debris can accumulate. It allows for thorough cleaning and disinfection, ensuring the water stored inside remains clean and safe for use.
  5. Longevity: The absence of seams in a tank contributes to its overall longevity. Since there are no weak points that are susceptible to deterioration or failure, a seamless tank is likely to have a longer service life. It can withstand environmental stresses and regular usage without the risk of structural degradation.
