Snyder Industries 230 Gallon Plastic Horizontal Leg Tank

The short one in the 38 inch wide family

Three tanks on this sheet share a 38 inch body width and they are told apart by length. This is the 52 inch one. Its sibling the SII-1003900N45 is the same 52 inches long and 38 inches wide at 42 inches tall and 225 gallons, listed heavier at 85 pounds; the SII-1320000N42 stretches to 72 inches for 300 gallons at 91 pounds in cross-linked polyethylene, as its own name gives it. So the reason to buy this one is that it is the most volume available in the shortest 38 inch wide body on the sheet, at the lightest weight of the three. Sixty-eight pounds is the number that changes how the tank gets used: two people lift it, one person with a hand truck moves it empty, and it goes onto a utility bed, a trailer tongue, a three point frame or a pickup without a crane or a permit. That is the whole case for a small leg tank, and it is why the mount deserves more thought than the tank. Legs want bearing along their whole length, which on a truck bed means running boards or a plywood deck rather than two cross members, and on the ground means a flat pad rather than dunnage under the ends. Strap it over the body, tight, with the straps checked after the first loaded mile, because there is no baffle inside and 1918 pounds of water in a 52 inch body will move the vehicle before the vehicle moves it. Haul it full or haul it empty. Check the volume against the job in the tank sizing calculator, and take the reserve and the expansion allowance from the tank sizing guide.

230 against 225 and 300 on one width

Take this one over the SII-1003900N45 when weight is the constraint: the two are the same 52 inches long on the same 38 inch width, but that one is listed at 42 inches tall and 225 gallons and 85 pounds against this tank's 43 inches, 230 gallons and 68 pounds. On a utility bed where every pound is already spoken for that listed weight gap is a real difference, and the taller body gains you volume rather than costing it. Take the SII-1320000N42 instead when the deck is long and the duty is bigger: 72 inches of body for 300 gallons at 91 pounds, in cross-linked polyethylene as its own name states, which asks for a longer mount than this tank needs. Within the three, this is the short, light, 43 inch tall 230 with a 10 inch lid and a 1.25 inch outlet, and it is the one to specify when the tank has to fit a space you have already measured and be lifted by the people who work there.

Ten inches of lid and 1.25 inches of outlet

• Vent: the sheet gives the lid as 10 inches and says nothing about a vent in it. Do not assume one. Even a small tank being drained has to take air in as liquid leaves, and a 230 gallon body with a sealed lid on a hot day is the classic case of a tank that deforms for no good reason. Order a vented lid or fit a breather, and keep the screen clear of dust and chaff.
• Headspace: 230 gallons is the rated volume and no separate fill line is published. Leave air above the liquid for expansion and for the slosh a short body generates in transit, and never fill to the rim of a 10 inch opening.
• Outlet: the sheet lists one outlet at 1.25 inches, and names no inlet, so the 10 inch lid is the fill point. An inch and a quarter is a hose connection, not a transfer line: it is right for gravity feed to a hand wand, a small pump or a fill jug, and it is the wrong choice if you expect to empty 230 gallons in a hurry.
• Plumbing: flexible at the first joint, the first valve supported off the frame rather than hanging on the tank, and the valve tucked inboard where a ramp, a gate or a tailboard cannot reach it. On a small tank the fitting is close to the ground and is the first thing to be hit.
• Limits: 120 F / 48 C, and 3645 pounds of contents at a specific gravity of 1.9 as the sheet gives it. No warranty term is published; ask us and we will get Snyder's current terms in writing.

Two things go wrong on tanks this size, and both are avoidable. The first is strapping over bare wall with a ratchet strap and cranking it: the body takes a crease, and the crease is where it eventually splits. Pad the strap, spread the load, and re-tension after the first mile rather than pulling harder on day one. The second is leaving it part full on a rough road. A 52 inch body with no baffle in it pushes its whole load against one end at every stop, and an empty tank rides better than a half one. Where it freezes, protect the valve and the short exposed run; the body is fine.

Spot spraying, hauled water and small batches

This is the tank that lives on a vehicle: a spot sprayer on a utility bed, water hauled to a stock trough or a remote pump, a mix and rinse supply on a service truck, weed control on a right of way, a small batch of a single process liquid taken out to where the work is, and a modest supply tank on a skid beside a shop. If the load is a blended fertilizer, the volume is small enough that people skip the mixing discipline and pay for it in the field, because a blend that sits between jobs layers and goes out of spec; the fertilizer blend stratification guide sets out the physics and the field checks that catch it. Mounting a tank this size for applicator work also raises a classification question that is cheaper to answer before the frame is welded than after: the applicator and leg tank scope article explains where the non-roadable trailer boundary falls. Where the liquid has to be contained rather than merely carried, the double wall walkthrough for 40 CFR 112 compares a contained vessel against a single wall inside a berm.

Service list by chemical

Three plants for a tank two people can lift

The sheet lists this tank from three plants, Lincoln, Nebraska, Philippi, West Virginia and Merced, California, which is the widest plant coverage of anything in this batch and it means most of the country is a short lane from one of them. Freight is LTL as the sheet gives it, NMFC 156600-02, shipping at 52 inches by 38 inches by 43 inches, so at 68 pounds it rides inside a trailer as ordinary freight rather than as a permitted load. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Ask about the liftgate before you ask about the rate, because a tank this light often lands somewhere with no dock at all. When it lands, fill it with water on the mount it will live on, not on the shop floor, and watch the legs and the outlet through the hold: a leg tank tells you about a bad mount the first time it is full, and never again politely. Keep the packing list with the part number on it, because on a fleet of small leg tanks the part number is the only thing that tells two similar bodies apart. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
