In order to reduce costs, many manufacturers will take old or improperly formed tanks and grind them back into poly powder. This powder is then used to supplement their virgin poly. However, the “regrind” poly causes the tank to lose its flexibility and leaves weak spots in the body of the tank. HiQual uses 100% virgin poly to guarantee the best quality, and we back it up with a five year warranty.

Rotational molding has other benefits as well. The flexibility of the tanks allows them to expand and contract as the weather changes. Unlike injection molded tanks, they don’t become brittle in freezing temperatures. In addition, the sides of a HiQual Poly Tank are smooth which limits algae growth and makes them easy to clean.
