Are Poly Water Tanks Still The Best Choice For A Durable Water Tank?
Posted by on
With myriad water tank solutions and material choices available today, polyethylene (poly) tanks have gained significant popularity due to their versatility, durability, and affordability. Whether it's for residential, agricultural, or industrial purposes, poly water tanks offer a range of benefits that make them a preferred choice for many households and business owners. However, like any product, they also have their limitations and considerations to keep in mind. In this blog post, we'll explore the key aspects of poly water tanks to help you make an informed decision.
What is the life expectancy of a poly water tank?
Poly water tanks are renowned for their longevity, with many manufacturers offering warranties ranging from 10 to 25 years or more, depending on the quality of the tank and the environmental conditions. Generally, a well-maintained poly tank can last anywhere from 20 to 30 years or even longer. Factors such as UV exposure, temperature fluctuations, and chemical exposure can affect the lifespan of the tank. Regular inspection and maintenance can help prolong its life further, ensuring reliable water storage for years to come.
Which is better: steel or poly water tank?
The choice between steel and poly water tanks often depends on specific requirements and preferences. Steel tanks are known for their strength and durability in high-heat situations, making them suitable for heavy-duty industrial applications. However, they can be prone to corrosion over time, especially in harsh environments.
On the other hand, poly water tanks offer excellent resistance to rust, corrosion, and chemical degradation, making them ideal for outdoor use and storing potable water. Additionally, poly tanks are lightweight, making them easier to transport and install compared to their steel counterparts.
When deciding on a water tank¹, always check with your local council for any bushfire regulations for steel water tanks in your area.
Are poly tanks safe for drinking water?
One of the most common concerns regarding poly water tanks is their safety for storing drinking water. Polyethylene is considered a safe material for water storage and is covered by Australian safety and regulations for contact with food and drinking water. High-quality poly tanks are manufactured using food-grade materials and undergo rigorous testing to ensure they meet safety and quality standards. Moreover, poly tanks do not impart any taste or odour to the stored water, ensuring it remains clean and fresh for consumption.
What are the disadvantages of polyethylene tanks?
While poly water tanks offer numerous benefits, they also have some limitations to consider. One of the main drawbacks is their susceptibility to UV degradation, which can cause the material to become brittle over time if not properly protected or treated with UV stabilisers. Ensure any tank you select is UV rated. Exposure to certain chemicals and extreme temperatures or fire can also affect the integrity of poly tanks, leading to premature wear and tear.
Summary
In conclusion, poly water tanks are a versatile and cost-effective solution for various water storage needs. Their durability, safety, and ease of maintenance make them a popular choice among homeowners, farmers, and businesses alike. However, it's essential to consider factors such as UV exposure, chemical compatibility, and maintenance requirements to ensure the longevity and performance of poly tanks. By understanding their strengths and limitations, you can make an informed decision when choosing the right water storage solution for your specific requirements.
