175 Gallon Vertical Liquid Storage Tank - Natural White (30" x 64"): Complete Buyer's Guide
A 175-gallon vertical liquid storage tank from Norwesco, 30 inches across and 64 inches tall, seamlessly rotomolded in 1.5-specific-gravity polyethylene for sprayer fills, mixing, and chemical day storage.
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
The 175-gallon vertical is a stocky, stable chemical tank that one or two people can set in place. It needs no engineered foundation — just a flat surface and a dosing line matched to the chemistry.
Site Preparation
Stand the tank on a firm, level surface that supports the full 30-inch base — compacted gravel, a flat pad, or a rated stand. Even support across the bottom is the requirement; over a concentrate, place it on a sealed surface or in a containment tray.
Placement and Connections
A foot of clearance handles service access. Plumb the outlet to your pump by the shortest run with chemical-rated flexible tubing, and match tubing, gaskets, and valves to the specific chemistry. The 64-inch height gives a useful head of pressure at the outlet.
Venting
Fit a lid vent so the wall does not pull inward on a draw, and a chemistry-rated vent if the contents off-gas.
Maintenance and Long-Term Care
Keep an eye on the seals and chemistry; the polyethylene shell looks after itself.
Quarterly Inspection Checklist
- Shell: scan the translucent wall for distortion or stress whitening.
- Seals and outlet: inspect the fitting and valves for swelling or hardening from chemical attack; hand-snug only.
- Base: confirm the tank stands flat and plumb.
- Vent: verify the lid vent is clear.
Cleaning and Chemical Changeover
Flush per the chemical manufacturer's protocol before changeovers, capturing rinsate for disposal, and confirm the incoming chemical against the polyethylene and seals before refilling.
UV and Weather Protection
The white wall passes some light; shade light-sensitive or algae-prone contents in strong sun.
Alternatives and Comparisons
The 175-gallon vertical sits between the 150 and 250 in the stocky 30-inch format. A cone-bottom of similar size drains completely for batch processing on a stand; the 250-gallon vertical is the next step up in straight storage volume.

Frequently Asked Questions
How long will the 175 Gallon Vertical Liquid Storage Tank - Natural White (30" x 64") last?
Within its 1.5 SG and 120 F ratings and with compatible chemistry, plan on 15 to 20 years. The seamless shell has no joint to fail, so seal compatibility and a flat base drive its real-world life.
What chemicals can I store in this tank?
The 1.5 specific gravity rating suits agricultural chemicals, fertilizers, and industrial solutions of that density; the resin meets FDA food-grade requirements. Not for fuels, solvents, or flammables. Check the chemical and the gaskets against a compatibility chart prior to filling.
Does this tank come with a warranty?
Norwesco's warranty answers for molding voids, pinholes, and factory fitting defects under normal use. Not covered: incompatible chemistry, misuse, and impact. Keep your receipt for any claim.
Can I install this tank underground?
No — it is an above-ground tank, and its walls cannot withstand soil pressure. If it must go below grade, use a tank rated for underground service.
Buying Considerations
Confirm a flat, firm base for the 30-inch footprint, a chemical at or under 1.5 SG compatible with the polyethylene and seals, and spill control for a concentrate. Freight is simple — the tank ships UPS or FedEx ground and usually lands within 5 to 7 business days.
