Rubbermaid Commercial Stock Tank – Durable Poly Construction for Long-Term Value

You’ll find Rubbermaid’s commercial-grade stock tanks offer exceptional durability that justifies their slightly higher used market price. These tanks consistently outlast cheaper alternatives while maintaining structural integrity through years of farm use.

Heavy-Duty Polyethylene Material Resists Cracking and UV Damage

Rubbermaid’s heavy-duty polyethylene construction withstands temperature extremes that crack inferior tanks within two seasons. You won’t see the brittle fractures around drain plugs that plague cheaper alternatives.

The UV-resistant formula prevents the chalky deterioration common in standard poly tanks. Your investment maintains its black color and flexibility even after five years of direct sunlight exposure.

Multiple Size Options to Fit Different Farm Operations

You can choose from 50-gallon options perfect for small goat herds up to 300-gallon models suited for cattle operations. The 100-gallon size works exceptionally well for most hobby farms with mixed livestock.

Rectangular designs fit efficiently against barn walls while oval models provide maximum capacity in tight spaces. Used markets typically offer 100-gallon and 150-gallon sizes most frequently.

Easy Installation and Maintenance Requirements

Installation requires no special tools beyond basic leveling of your chosen location. You’ll appreciate the reinforced drain plugs that don’t strip out during routine cleaning like cheaper alternatives.

Maintenance involves simple scrubbing with farm-safe cleaners twice yearly. The smooth interior walls prevent algae buildup that creates cleaning nightmares in textured tanks.

Behlen Country Galvanized Round Tank – Classic Steel Durability at Affordable Prices

Behlen Country tanks represent the gold standard in traditional livestock watering systems. You’ll find these galvanized steel workhorses on used equipment lots nationwide, offering proven reliability at budget-friendly prices.

Corrosion-Resistant Galvanized Coating for Extended Lifespan

The hot-dipped galvanized coating on these tanks creates a zinc barrier that actively prevents rust formation for 15-20 years. You’ll notice minimal surface corrosion even on decade-old units, making them excellent used purchases. This coating bonds directly to the steel substrate, providing protection that paint simply can’t match for outdoor livestock applications.

Traditional Round Design Maximizes Water Capacity

Round construction eliminates corner stress points that cause cracking in rectangular tanks over time. You get maximum water volume per square foot of ground space – a 6-foot diameter tank holds 170 gallons while fitting in tight barn corners. The circular shape also promotes better water circulation, reducing stagnation and algae growth during summer months.

Wide Availability in Used Equipment Markets

Farm auctions and equipment dealers consistently stock Behlen tanks due to their widespread original adoption across rural America. You’ll typically find 100-300 gallon models priced 40-60% below new retail, with 8-foot diameter units being the most common size available. Local farmers often upgrade to larger systems, creating steady inventory of quality used options.

Tarter Farm and Ranch Oval Stock Tank – Space-Efficient Design for Smaller Properties

Tarter’s oval design offers a smart solution when you’re working with limited space or awkward property layouts. You’ll find these tanks particularly valuable for smaller operations where every square foot matters.

Oval Shape Fits Tight Spaces and Corner Installations

Oval tanks maximize water capacity while minimizing your property footprint. You can tuck these units against barn walls, fence lines, or in narrow paddock corners where round tanks won’t fit. The elongated shape provides more drinking space for multiple animals without requiring the wide clearance circles that traditional round tanks demand.

Reinforced Sidewalls Handle Heavy Livestock Use

Heavy-duty sidewall construction withstands pushing and rubbing from cattle and horses. Tarter incorporates additional ribbing and thicker gauge steel in high-stress areas where animals typically lean or push. You’ll notice less denting and warping compared to standard oval tanks, even with aggressive livestock behavior during hot weather.

Cost-Effective Alternative to Custom Water Solutions

Used Tarter oval tanks cost 30-50% less than custom corner waterers or specialized space-saving systems. You’re getting proven durability without paying premium prices for custom fabrication. Most used units retain their structural integrity for decades, making them excellent investments when you need efficient watering solutions on a tight budget.

You’ll find Little Giant galvanized stock tanks consistently available in used equipment markets, offering dependable water storage without the premium price of specialized livestock systems.

Proven Track Record in Agricultural Applications

Little Giant tanks have earned their reputation through decades of farm use across diverse climates and livestock operations. You’ll often find these tanks still functional after 20+ years of continuous outdoor exposure, with many showing only minor surface rust that doesn’t affect performance. Their widespread adoption by commercial dairies and ranches demonstrates proven reliability in demanding agricultural environments.

Leak-Resistant Construction Minimizes Water Waste

The welded seam construction creates watertight joints that rarely develop leaks even after years of thermal expansion and contraction. You’ll appreciate the reinforced bottom design that prevents sagging and maintains structural integrity under full water loads. This robust construction means fewer refills and reduced water waste compared to tanks with compromised seals.

Reasonable Pricing in Secondary Markets

Used Little Giant tanks typically sell for 35-45% of their original retail price, making them accessible for budget-conscious operations. You’ll find 100-gallon models averaging $150-200 in good condition, while 200-gallon versions range from $250-350 depending on age and surface condition. Their consistent availability means you won’t pay premium prices often associated with harder-to-find specialty tanks.

Fortex tanks stand out in the used market because they’re built for farm versatility beyond just livestock watering. You’ll find these tanks hold their value well since farmers use them for everything from feed storage to emergency water supplies.

Food-Grade Materials Safe for Livestock Consumption

Fortex uses FDA-approved polyethylene that won’t leach chemicals into your animals’ water supply. This food-grade construction means you can safely use these tanks for drinking water without worrying about plastic contamination affecting animal health. Even used Fortex tanks maintain this safety standard since the material doesn’t degrade with age.

Lightweight Design Simplifies Transportation and Setup

These plastic tanks weigh 60% less than comparable galvanized steel options, making them easy to move with basic farm equipment. You can relocate a 150-gallon Fortex tank with a standard utility trailer instead of heavy machinery. Installation requires minimal ground preparation since the lightweight design puts less stress on foundations.

Chemical Resistance for Various Farm Uses

Fortex tanks resist common farm chemicals like fertilizers, cleaning solutions, and livestock medications that would corrode metal alternatives. This chemical resistance extends their usable life when repurposing for feed storage or mixing applications. Used Fortex tanks often show minimal chemical staining compared to metal tanks with pitting and corrosion damage.

Miller Manufacturing Galvanized Tank – Heavy-Duty Construction for Large Operations

Miller Manufacturing tanks stand out in the used market because they’re built like commercial equipment from day one. You’ll find these tanks holding their value and performance even after decades of heavy farm use.

Extra-Thick Steel Walls Withstand Extreme Weather

Miller tanks use 20-gauge galvanized steel that laughs at wind, hail, and temperature swings. I’ve seen 15-year-old Miller tanks that still look solid while thinner competitors show dents and warping. The extra steel thickness means your used tank investment won’t buckle under livestock pressure or storm damage.

Large Capacity Options Reduce Refilling Frequency

You’ll find used Miller tanks ranging from 300 to 1,500 gallons, perfect for large herds or remote pastures. The 750-gallon models hit the sweet spot for most operations – enough water for 50+ cattle for several days. Fewer refill trips mean lower fuel costs and more time for other farm tasks.

Strong Resale Value Protects Your Investment

Miller tanks retain 60-70% of their original value even after 10-15 years of use. Their reputation for durability keeps demand high in used equipment markets. When you’re ready to upgrade or downsize, you’ll recover more of your investment compared to lesser-known brands that depreciate faster.

You’ll save 50-70% compared to new tanks while getting units that have been structurally tested by pool use. Many sellers include pumps, filters, and fittings that work perfectly for automatic waterer setups.

Previously Used Tanks at Significantly Reduced Prices

Pool conversion tanks typically sell for $200-400 regardless of original retail price since sellers want quick removal. You’ll find premium brands like Behlen and Stock Tank Pool Co. at fraction costs. Facebook Marketplace and Craigslist show the best selection during late summer when families drain seasonal pools.

Inspection Tips for Ensuring Structural Integrity

Check for stress cracks around drain holes where pool fittings were installed – these indicate potential failure points. Look for uniform galvanizing on steel tanks since pool chemicals can cause accelerated corrosion in spots. Avoid tanks with multiple mounting holes unless you can properly seal them for livestock use.
