The Norwesco 100 Gallon Doorway Water Tank (SKU N-44800) is a narrow polyethylene tank built to clear a standard doorway: at 22 inches wide and 38 inches long, with a 45-inch height, it fits through openings, hallways, and stairwells where a round tank never could. It holds 100 gallons, weighs about 834 pounds full of water, and carries a 1.5 specific gravity rating that lets it hold contents up to 1,251 pounds. That makes it a practical choice for indoor water storage, basement and crawlspace installs, garage and shop supply, and tight retrofit jobs where access is the constraint.
Will this doorway tank work for your site?
The deciding factor on a doorway tank is geometry, not capacity, so measure all three dimensions before you order. The 22-inch width is what clears the door opening; the 38-inch length governs how it turns in a hallway; and the 45-inch height has to pass under stairwell and basement headroom. Map the full path from your truck to the final spot against each of those numbers. Once it is in place, the footprint is 22.0 x 38.0 inches, so it sits flat against a wall without eating up floor space, and the full-water weight of 834 pounds is the load your floor or pad must carry, so verify the supporting surface before filling. If you are weighing this 100-gallon size against a larger doorway tank, the Tank Sizing Calculator and Tank Sizing Guide help you match capacity to demand, and the Norwesco Doorway Tank Sizing Guide walks the 100 to 1000 gallon range by application.
Specifications
Manufacturer: Norwesco. Capacity: 100 gallons. Color: White. Material: polyethylene. Specific gravity rating: 1.5. Height: 45 inches. Width: 22 inches. Length: 38 inches. Footprint: 22.0 x 38.0 inches. Full-water weight: 834 pounds; maximum rated contents weight: 1,251 pounds. Tank type: doorway tank. The 1.5 specific gravity rating means the tank wall is rated for fluids up to 1.5 times the density of water, which is where the 1,251-pound contents ceiling comes from. For inlet, outlet, and lid sizes plus fitting locations, confirm them against the technical drawing on this page before you order any fittings or gaskets.

The mistake to avoid
The most common error here is buying for the gallons and skipping the tape measure. This tank earns its name from the 22-inch width, but the hallway turn and the stairwell headroom catch just as many people, so check the door, the turn, and the height before ordering. The second point worth noting: the 1.5 specific gravity rating is set for water and water-weight contents up to 1,251 pounds. This is a water tank; keep it in water and water-like service rather than dense chemical duty. If your application leans toward fire-water reserve or reuse storage, the fire-water reservoir design guide and the industrial water reuse topology guide are worth reading.
