1050 Gallon 20 Degree Cone Bottom Tank with Poly Stand: Complete Buyer's Guide
The 1,050-gallon 20° cone-bottom tank supplied complete with its matching poly stand — a turnkey full-drain mixing vessel from Norwesco. The shallow 20-degree cone keeps the mounted height modest while still draining to a central apex outlet, and the included poly stand carries the load correctly through the tank's support ring. Built from virgin linear polyethylene rated for chemical service.

Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.5 — the tank is engineered for liquids up to 1.5× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Installation and Setup Guide
This combo pairs the 1,050-gallon 20-degree cone tank with a fitted poly stand, so installation is mainly about siting the stand correctly. The load rides through the stand and the tank's support ring — never the cone apex — which makes the stand's footing and levelness the safety-critical part of the job.
Site Preparation
Set the poly stand on a firm, level surface — a concrete slab or a well-compacted pad — sized to support the stand's footprint and the full weight of the charged tank. Level the stand dead-true so the shallow 20-degree cone drains evenly to its center; because the slope is gentle, a tilt will strand product on the high side more readily than a steeper cone would. Clear the area of anything that could undermine the footing.
Placement and Connections
Seat the tank fully into the stand's support ring before adding any liquid, and confirm the apex hangs clear with no contact at the tip. Plumb the apex outlet with a full-port valve so product clears without bridging, using schedule-80 PVC or stainless and a flex section before rigid pipe. Keep the discharge run short and route it without low spots so the shallow cone drains freely.
Venting
A cone tank empties quickly through its apex and can pull a vacuum if the vent cannot keep pace. Size the lid vent to your maximum drain rate, and for any chemical that off-gasses use a pressure-vacuum relief vent rated for the product's vapor.
Maintenance and Long-Term Care
The included poly stand joins the tank on your inspection list, and because it carries the load it deserves first attention. A quarterly routine covers tank and stand together.
Quarterly Inspection Checklist
- Poly stand: Check the legs, joints, and feet for cracking, distortion, or movement under the charged load.
- Cone and support ring: Confirm the tank seats evenly in the ring and look for stress whitening at the cone shoulder.
- Apex outlet: Verify the valve seals and the shallow cone drains freely, with no product bridged above it.
- Vent: Leave the lid vent unblocked so a fast outflow does not vacuum the wall inward.
Cleaning
The cone's advantage is at cleanup: open the apex valve and the tank self-drains nearly completely. Rinse from the lid with a solution that neutralizes the previous chemical and let it clear through the cone, giving thicker residue an extra pass since the slope is gentle. Collect the rinsate for disposal following the chemical's safety data sheet.
UV and Weather Protection
The elevated tank presents a south wall to the sun; check that face annually for chalking. A poly stand resists weather well, but inspect it over the years for sun embrittlement just as you would the tank.
Alternatives and Comparisons
This combo's advantage is convenience — tank and matched poly stand together, ready to plumb. The same 1,050-gallon cone is also sold without a stand, which costs less up front but requires you to source and size a compatible, load-rated stand yourself. The 20-degree cone here keeps height down and drains free-flowing liquids well; a 30-degree cone of similar volume drains thicker product more aggressively but stands taller. And if you do not need complete drainage at all, a flat-bottom vertical tank is the cheaper, lower, simpler option that accepts a small residual heel.
Frequently Asked Questions
How long will the 1050 Gallon 20 Degree Cone Bottom Tank with Poly Stand last?
With operation on compatible chemistry, a sound stand, and a properly supported, level base, a tank of this build serves reliably for many years. The seamless polyethylene shell has no joints to fatigue and carries UV protection in the resin; with a cone-and-stand combo, the stand is part of that lifespan, so keep it inspected and sound. Chemical attack from an incompatible product and a vacuum from a clogged vent are the avoidable failure modes.
What chemicals can I store in this tank?
As a chemical-service cone tank it suits most fertilizers, ag chemicals, and many acids and bases compatible with polyethylene, with the cone aiding products that need full recovery between batches. The shallower 20-degree cone favors free-flowing liquids. Polyethylene does not tolerate strong oxidizers, many solvents, or flammable fuels — confirm your specific product on a poly compatibility chart before filling.
Does this tank come with a warranty?
Yes — Norwesco warrants the tank against material and workmanship defects: factory fitting defects, pinholes, and molding flaws. Coverage excludes chemical attack from incompatible products, resting the cone on its apex, an inadequate base under the stand, and impact damage. Keep proof of purchase and a photo record of the install on hand for claims.
Can I install this tank underground?
No. This is an above-ground, stand-mounted cone tank built for gravity drainage above grade; its geometry would fail under soil pressure if buried. Below grade, choose a purpose-built underground cistern designed for soil and groundwater pressure.
Buying Considerations
Confirm three points before ordering this combo. First, the working height — the tank arrives mounted on its poly stand, so plan lid access above and apex-valve clearance beneath. Second, the stand footing — provide a firm, level slab or pad to carry the charged weight through the stand's feet. Third, the chemistry and freight — confirm your product is polyethylene-compatible, and expect the tank-and-stand to ship palletized with lift-gate unloading. Call us with any questions on the combo or its specifications.
