Norwesco 100 Gallon Doorway Water Storage Tank Without Fitting in White

The Norwesco 100 Gallon Doorway Water Storage Tank (SKU N-43311) is built for one job the standard round tank cannot do: fit through a doorway. At just 13 inches wide, 48 inches long, and 43 inches tall, this white polyethylene tank clears a standard door opening and slides into basements, utility closets, mechanical rooms, and retrofit spaces where a wider tank would never go. It holds 100 gallons, weighs 47 pounds empty, and ships without a fitting so you specify the outlet and plumbing that match your install.

Will it work for your water storage?

This is a dedicated water tank rated for a specific gravity of 1.1, so it handles water and light water-based contents comfortably. Full of water, expect roughly 834 pounds of contents. The 917-pound max-contents figure is not spare margin above a full water load: it is that same 834 pounds of water carried at up to 1.1 specific gravity, so treat it as the ceiling, not headroom on water. Plan your pad and floor loading for the filled weight on a 13 x 48 inch footprint. The polyethylene is FDA approved and rated to a maximum service temperature of 120 F (48 C). A 5 inch lid gives you top access for fill, cleaning, and inspection. Because it ships without a fitting, size your outlet before install and use the Tank Sizing Calculator or Tank Sizing Guide if you are matching this 100 gallon tank to a daily draw or a fire-reserve requirement.

The mistake to avoid

Do not treat this as a chemical tank. The 1.1 specific gravity rating is set for water and water-like contents; heavier liquids need a tank rated for a higher specific gravity, and this white water model is not sold for chemical service. The other mistake is plumbing. The only factory penetration on this tank is the 5 inch lid; every outlet is field-added. Order a bulkhead fitting plus the matching gasket sized to your outlet, and cut it to your chosen outlet height rather than improvising after the tank is set. And confirm your clearances before delivery: a standard interior door rough opening runs about 32 inches, so at 13 inches wide by 48 inches long this tank clears it flat or on edge, but measure your narrowest turn, such as a stair landing or hallway corner, against the 48 inch length. A filled tank cannot be moved, so stage it empty in its final position and plumb it there.
