Snyder Industries 30 Gallon Plastic Horizontal Leg Tank in White

What a 30 gallon leg tank actually gets used for

The duty is a small dose or a small carry, close to the work. A grower runs 30 gallons of spray mix on a utility vehicle down the rows where a full-size nurse tank cannot turn. A grounds crew keeps one on a trailer for hand-wand weed control and washes it out between jobs. A shop keeps one under a drum pump as a decant vessel so the drum stays where it belongs. A feed or dairy operation carries wash water to a pen. A construction outfit puts one behind a mower or a compact tractor for dust knock-down on a footpath. A service van carries 30 gallons of clean water for flushing a line. In each case the buyer is not short of gallons, they are short of room and short of hands, and 20 inches of length with 12 pounds of tank is what makes the job possible at all. What the shape asks in return is a flat, continuous surface under the full length of the legs: a deck, a plywood-topped skid, a pallet, a poured pad. Not two rails with a gap in the middle, not one leg hanging over an edge, not a bolt driven through a leg. Strap it over the body, and remember what is above those legs once it is full: 250 pounds of water, 475 pounds at the rating, all of it free to move every time the vehicle turns. Work the volume out properly before you buy rather than after, because 30 gallons is a short interval on a spray job: put the draw rate and the refill trip through the tank sizing calculator, and take the freeboard a warming liquid needs from the tank sizing guide. Where the load is a blended fertilizer that has to leave the tank on spec, the fertilizer-blend tank stratification article is worth the read first, because a small body with a shallow depth stratifies and settles on a different clock from a tall one.

The 30 against the 60 in the same family

The sheet lists exactly one other tank beside this one and the choice between them is floor space, not gallons. The 60 gallon SII-1060000C26 doubles the volume and stands at the same 26 inches tall, but it takes 39 inches of length and 48 inches of width where this tank takes 20 by 23, and it weighs 23 pounds against 12. If the space you are fitting is a utility vehicle cargo box, a narrow trailer tongue, a bench or the back of a service van, the 30 is the only one of the two that goes in, and it goes in without help. If the space is a flatbed or a trailer deck and the refill trips are the annoyance, buy the 60 and stop walking. There is one honest oddity to report on this family and we would rather print it than tidy it: the sheet gives this tank as 20 inches long by 23 wide by 26 tall, taller than it is long, and gives the 60 as 39 long by 48 wide, wider than it is long, on tanks it calls horizontal leg tanks. Those are the figures on the sheet and those are the figures we publish; we do not interpret them and we will confirm the orientation of the part you are ordering before it ships. Measure the space against all three dimensions rather than against the one the name suggests.

Draining a 20 inch body through a 6 inch lid

• The pump and drain path: the sheet publishes no outlet and no inlet on this part, so we name no pipe size, no valve and no bulkhead fitting. What that means practically is that the draw arrangement is specified with the order. Tell us whether the liquid leaves by a transfer pump, by gravity to a wand, or by a siphon through the lid, and the fitting is matched to the job rather than guessed at on a page.
• Prime on a small body: 30 gallons at 26 inches of height gives very little standing column, so a pump mounted above the liquid will lose prime near the end of every load. Set the pump below the tank, keep the suction run short and falling, and put a run-dry stop on it. A self priming pump or a foot valve is the right answer on a tank this size.
• Filling and access: a 6 inch threaded vented lid is the fitting the sheet gives. Six inches is a hose fill and a rinse port, not a hand-and-arm access, so plan the wash-out routine around the opening that exists. Fill with the hose end inside the rim rather than dropping liquid in from above.
• Keep the vent clear: the lid is listed as vented, and that vent is the reason the wall survives a pump drawing hard on 30 gallons. A blocked vent on a body this small pulls the sides in quickly. Look at it every time the lid comes off.
• Draining the last of it: with no low-point fitting on the sheet, the last gallons come out by tipping 12 pounds of empty tank or by siphon. That is genuinely easier here than on any larger tank in the line, and it is a real argument for the 30 on a job where the liquid changes often.
• Service limit: 120 F / 48 C, the only limit this sheet publishes.

Whatever the draw arrangement, break the first joint off the tank with a flexible connector and carry the weight of a valve or a filter on its own bracket rather than on the tank wall. A tank that rides on a vehicle takes every bump through its fittings, and 12 pounds of polyethylene is not a pipe support. Name the liquid when you order so the lid gasket and any fitting we add are matched to it, and where a regulated product is being stored or carried and somebody has asked about a second wall, the Snyder Captor double-wall SPCC walkthrough is where containment gets argued properly instead of assumed.

Small loads on small vehicles

This size does row-crop and orchard spot spraying, grounds and turf work, wash and rinse water on a livestock or equipment yard, decant and transfer duty under a drum in a shop, dust control on paths and small lots, and clean water carried in a service vehicle. Where you are still choosing between a leg tank, a loaf tank and an applicator tank for the vehicle you already own, the applicator and leg tank guide compares the shapes against the duty rather than against the price list.

Four plants, one carton, twelve pounds

The sheet lists four plants for this part: Chowchilla, California; Lincoln, Nebraska; Marked Tree, Arkansas; and Philippi, West Virginia. That is the widest plant list on any part in its batch, and on a small item it is the difference between a short lane and a long one wherever you are. The freight class field reads UPS under NMFC 156600, which is a ship mode rather than a numeric class, and at 12 pounds in a 20 by 23 by 26 inch box that is exactly what it means: this one travels as a parcel rather than on a pallet. Price your lane with the freight cost estimator; the listed price is before freight. When it lands, fill it with clean water on level ground, watch the legs for full contact and the 6 inch lid for weeping through one full load, then drain it before the working liquid goes in. One person can do all of that in ten minutes, which is the whole point of a 30 gallon tank, so do it on the day it arrives and not the week the sprayer is due out. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
