When you’re shopping for cheap water tanks, it’s easy to think all tanks are basically the same—just a big container that holds water. But in Australia’s harsh climate, the real difference between cheap and quality water tanks often shows up months (or years) later through leaks, cracks, fading, poor performance, or unexpected replacement costs.
At Great Northern Tanks (Australia), we often speak to customers who started with cheap water tanks to save money, only to upgrade later when problems appear. In this guide, we’ll break down the real differences between cheap water tanks vs quality water tanks, so you can choose the right solution for your home, farm, business, or rural property.
Cheap Water Tanks: Why They Look Like a Great Deal
There’s a reason cheap water tanks sell quickly—especially when you’re trying to stick to a tight budget.
A lower price can be appealing when you’re:
- Building a new home and managing multiple costs
- Replacing an old tank urgently
- Trying to install extra rainwater storage without overspending
- Looking for a “temporary” setup
Some cheap water tanks may look similar to premium tanks online. They often come with similar shapes, sizes, and even colour options. But the difference is usually hidden in the materials, manufacturing process, fittings, and warranty conditions.

Cheap Water Tanks vs Quality Water Tanks: The Material Matters Most
If you want to understand the true difference between cheap water tanks and quality tanks, start with what the tank is made from.
Cheap water tanks often use lower-grade plastic
Many cheap water tanks are made using thinner or lower-quality polyethylene. That may mean:
- Less resistance to UV exposure
- Faster fading, brittleness, or cracking
- Reduced strength under pressure (especially when full)
Quality water tanks use stronger, long-life materials
High-quality tanks are typically made with:
- UV-stabilised polyethylene designed for Australian conditions
- Thicker walls and a more consistent build
- Better structural integrity for long-term storage
At Great Northern Tanks, we focus on quality water tanks that are designed for real Australian weather—heat, sun, wind, and long-term outdoor use.
Cheap Water Tanks and UV Protection: The Australian Sun Is No Joke
In Australia, UV exposure is one of the biggest reasons cheaper tanks fail early.
Cheap water tanks can degrade faster outdoors
Lower-cost tanks may:
- Become chalky and brittle over time
- Fade quickly and weaken internally
- Develop cracks after repeated expansion and contraction
Quality water tanks resist UV and temperature stress
A quality tank is made to handle:
- Long summers in full sun
- Temperature swings that cause plastic to expand and contract
- Outdoor placement for years without losing strength
This is one reason many Australians choose quality water tanks from Great Northern Tanks—because the tank is expected to last, not just “get by”.
Cheap Water Tanks vs Quality Water Tanks: Wall Thickness and Strength
Not all tanks have the same wall thickness, even if they look identical in photos.
Cheap water tanks can flex and weaken under pressure
When the tank is full, thousands of litres create pressure on the walls and base. Cheaper tanks may:
- Bulge or flex more
- Struggle with uneven ground
- Fail sooner if installed without the perfect foundation
Quality water tanks hold shape better and last longer
Higher-quality tanks typically:
- Stay more stable when full
- Handle pressure better
- Offer more reliability for rural and high-demand environments
If your water supply is critical (and in many areas of Australia, it is), quality matters more than the initial price tag.
Cheap Water Tanks and Fittings: Small Parts, Big Problems
A major issue with cheap water tanks is often not the body—it’s the components.
Cheap water tanks may have poor outlets and seals
Many budget water tanks use fittings that can lead to:
- Slow leaks
- Poor sealing
- Cracked outlets over time
- Compatibility issues with pumps and plumbing setups
Quality water tanks support better performance
Quality water tanks are typically built to work smoothly with:
- Pumps and pressure systems
- Irrigation setups
- Filtration and household plumbing
When you’re buying water tanks in Australia, it’s worth thinking beyond “just storage” and focusing on how the entire system will function.
Cheap Water Tanks vs Quality Water Tanks: Water Safety and Clean Storage
If you plan to use your tank for household use, animals, irrigation, or drinking supply, the quality of storage matters.
Cheap water tanks may cause water quality issues
Some cheaper tanks can:
- Allow more light penetration, encouraging algae growth
- Have weaker lids that don’t seal properly
- Be harder to maintain long-term
Quality water tanks help keep water cleaner
Premium tanks are usually designed to:
- Reduce light entry (to help limit algae)
- Seal properly and keep pests out
- Maintain better water conditions for long-term storage
For many Great Northern Tanks customers, clean and reliable water storage is the main reason they upgrade from cheap water tanks to quality water tanks.
The Real Cost of Cheap Water Tanks in Australia
Buying cheap water tanks can work out fine if the tank suits your application. But the real problem is when cheap becomes expensive later.
Here’s what can increase the long-term cost of cheaper tanks:
- Replacement sooner than expected
- Extra plumbing or repairs
- Water loss from leaks
- Stress and downtime when the tank fails
- Installation costs repeated (delivery + setup again)
A quality water tank may cost more upfront, but it often delivers better value across 10–20+ years of use.
Cheap Water Tanks vs Quality Water Tanks: Warranty and Support
If two tanks look similar but one comes with a stronger warranty, that’s a major signal of quality.
Cheap water tanks often come with limited coverage
Some budget tanks offer:
- Shorter warranty periods
- Strict terms and conditions
- Less clarity on what is (and isn’t) covered
Quality water tanks usually come with better confidence
A quality tank supplier stands behind their product and provides stronger protection.
At Great Northern Tanks, you can view our warranties and choose with confidence knowing your tank is backed by support designed for Australian conditions.
When Cheap Water Tanks Might Be the Right Choice
Not everyone needs the highest-end tank—and that’s okay.
Cheap water tanks may be suitable if:
- You need short-term water storage
- You want a backup tank for non-critical use
- Your water demand is low
- You’re buying during a discounted period
A smart way to buy cheap water tanks without sacrificing reliability is to shop from a trusted supplier offering deals and verified quality.

Choosing the Best Option: Cheap Water Tanks That Still Deliver Quality
The best purchase is not always the cheapest—it’s the one that performs best over time.
Before buying cheap water tanks in Australia, consider:
- Where the tank will be installed (full sun or shaded?)
- How long you need it to last
- What the water will be used for
- Whether you’ll connect a pump system
- The warranty support available
At Great Northern Tanks, we offer a trusted product range for Australian homes, farms, businesses, and rural properties—so you can choose the right size and style without guessing.
Final Verdict: Cheap Water Tanks vs Quality Water Tanks
The real difference between cheap water tanks and quality water tanks comes down to:
- Material strength and thickness
- UV protection for Australian conditions
- Fittings and long-term leak resistance
- Clean water storage performance
- Warranty coverage and peace of mind
- Cost over the tank’s lifetime—not just day one
If you’re aiming for the best value long-term, investing in quality water tanks often saves money, time, and stress.
