Important Notes Before You Order
Though these tanks can be placed in any position, if they are placed up on edge with a height of 18" or more, they will need to be fully supported and braced or tank failure will occur.
Due to the nature of the rotational molding process, dimensions may vary from what is published and shown on the referenced drawings.
During the delivery process, tanks can pass between several docks and trucks on their way from the factory to the customer. Though not a guarantee, tank wrap “helps” to protect the tanks from getting scuffed and dirty. The best way to avoid cosmetic damage is to set up a will call at the factory and personally handle the tanks yourself.
Though our line of holding tanks is ideal for use as rv holding tanks and rv holding tank system, they can be used in a variety of circumstances. Call one of our specialists today to get more information on our full line of water holding tanks.
