A 75 gallon black water tank, 23 inches across and 50 inches tall
The Norwesco 75 gallon vertical water storage tank, part number 41457, is a black polyethylene tank 23 inches in diameter and 50 inches tall, weighing 38 lb empty. It is the size that fits through a standard door and still holds a useful reserve: a day or two of household water, a pressure pump buffer, a rinse supply for a shop, or a rain reserve for a garden. It comes with a 1-1/4 inch polypropylene female NPT bulkhead fitting as the outlet and a second 1-1/4 inch polypropylene female NPT bulkhead fitting as the inlet. The tank is rated for water, specific gravity 1.0; 75 gallons of water weighs 626 lb. The resin is FDA compliant and UV stabilized, and Norwesco backs the tank with a 3 year warranty. Black keeps light out of the water, which slows algae in a tank that sits in a bright room or in the sun.

Where a 75 gallon vertical goes
At 23 inches across, this tank passes through a doorway and a hallway, which is why it ends up in utility rooms, well houses, basements and closets as the household reserve or the pump drawdown tank. Outdoors it is a rain barrel with twice the capacity of the usual barrel, on a stand under a downspout, or a feed and rinse reservoir beside a greenhouse bench. Standing 50 inches tall, it puts the water surface about four feet above the outlet, which floods a small pump and runs a slow gravity line to anything lower down. At 38 lb empty one person moves it; full, it is 626 lb on a 23 inch circle, so the floor under it must be flat and continuous, and a narrow tank is easier to tip than a wide one, so strap it or set it against a wall where people, animals or vehicles pass. The 1-1/4 inch fittings suit a hose, a float valve or a small pump line; if you need a 2 inch drain, the 100 gallon tank in this family carries one. Check your real draw and refill interval with the tank sizing calculator and set the reserve from the tank sizing guide.
Openings and fittings
- Outlet. A 1-1/4 inch polypropylene female NPT bulkhead fitting, factory installed low in the wall. Your valve or hose adapter threads straight in. Support the valve and the first length of hose on their own so the fitting carries water, not hardware.
- Inlet. A 1-1/4 inch polypropylene female NPT bulkhead fitting for a fill line, a float valve or an overflow run to daylight away from the base.
- Top opening. Tell us how you plan to fill and clean the tank and we will confirm the top opening on this part number before it ships.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the fitting positions.

Shipping and receiving
The tank ships LTL at freight class 250 from Norwesco's Burnet, Texas plant, 23 by 23 by 50 inches on a pallet at a ship weight of 38 lb. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP, or request a written quote. It needs a flat, level, continuous surface under the whole 23 inch floor; for an outdoor base the concrete pad sizing guide has the framework. At the tailgate, check the part number against 41457 on the bill of lading and look at the wall and both fittings for transit damage. Fill it with water the first time and watch the fittings for a day before it goes into service; the water fill acceptance test guide gives the method.
