400 Gallon Norwesco Doorway Water Tank in Natural White
The Norwesco N-43856 is a 400 gallon doorway tank: a tall, narrow, flat-sided tank built to go where a round tank can't. It measures 66" long x 29" wide x 70" high. With its narrowest side at 29 inches, it's designed to pass through a standard doorway, so it can go into a basement, garage, utility room or cabin and stand against a wall. Measure your door opening and any tight turns first, and allow for the fittings.

- Plan the path in. Check door openings, hallway turns and stairs against the tank's width and height before delivery.
- Leave room at the top. Keep access to the lid for filling, cleaning and inspection.
- Keep it cool. Don't store liquids hotter than 120°F, and keep the tank away from heaters and furnaces.
