The 300 gallon doorway water tank in white
The Snyder WV21 is a white polyethylene water tank that holds 300 gallons in a shell 35 inches across and 80 inches tall, weighing 71 pounds. It goes through a standard door, stands in a utility room or a well house, and the white wall shows the water level in daylight. A 1-1/2 inch inlet, a 2 inch outlet, an 18 inch vented manway, and a rating of 1.0 specific gravity for water and liquids no heavier. White is for indoors or shade; in sun it lets light in and the water grows algae, which is what the black and green tanks are for.

A tall, narrow tank in a closet
More than twice as tall as it is wide, the WV21 wants a level floor and a strap to a stud, because 2,502 pounds of water on a 35 inch circle has a high center of gravity. The reward is 300 gallons on a footprint smaller than a pallet, with 80 inches of head that gives a garden hose a usable flow by gravity and keeps a pressure pump's suction flooded. The 300 gallon doorway water tank buyers guide compares the narrow shapes at this volume across makers, and the tank sizing calculator tells you whether 300 gallons covers the draw.
Snyder's 120 to 330 gallon verticals
| Part | Gallons | Diameter x height | Empty weight |
|---|---|---|---|
| WV21 (this tank, white) | 300 | 35 x 80 in | 71 lb |
| WB21, black | 300 | 35 x 81 in | 65 lb |

The WB21 is the same doorway tank in black for outdoors. The 32241 is 8 inches shorter on a 36 inch base, and the 1011200N52 is 2 inches taller; both are heavier-wall tanks for liquids denser than water. The 1008200N52 lays 330 gallons down to 50 inches on a 47 inch base, and the 1540200W94303 is the 120 gallon step down at 41 inches.

Ports and manway
- Inlet: 1-1/2 inch.
- Outlet: 2 inch, at the base.
- Access: 18 inch vented manway, half the diameter of the tank.
- Service limit: 120 F / 48 C.
A 2 inch outlet on a 300 gallon tank feeds a small pressure pump without starving it. An 18 inch manway on a 35 inch tank reaches the whole floor for cleaning, and the white wall means no sight tube: the level reads through the shell. In a freezing climate insulate or drain the outlet valve and the first run of pipe; the body takes ice from the top down without harm.
Who buys this tank
Well buffer in a utility room, emergency water in a garage, a mixing or rinse tank in a shop, and one cell of a small fire reserve of the kind the fire-water reservoir design guide describes. Indoors, several of them are the storage stage of a small reuse system for roof water and condensate, per the industrial water reuse tank topology article; the tank sizing guide covers days of supply.
Shipping the tank
The WV21 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. One person carries 71 pounds through the door. Strap it, fill it to the manway once, and check both fittings before it goes to work; keep a screen on the inlet and the vent. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
