Elkhart Plastic tanks are manufactured to meet quality and health safety standards. With fewer impurities, these tanks are strong enough to take the bumps and bangs without compromising the security of your fresh water storage. Elkhart Plastics uses a process called roto-molding in which high-density plastic is rotated and molded into shape. This process creates a seamless tank in which the walls are of equal thickness, with no weak spots to cause trouble later. It is this process that has earned Elkhart Plastics the reputation for quality tanks.
THE SEALED HOLE ON TOP OF THE TANK IS FROM THE MANUFACTURING PROCESS. IT IS A VENTING HOLE USED DURING THE CREATION OF THE TANK. IT HAS NO FUNCTIONAL USE FOR THE END-USER.
