How long do plastic water tanks last?

There are poly tanks that have been giving loyal service storing liquids for over 10 years, however there is no definite "life" period for a poly tank.

As with any other product you buy, its "life" will depend on how you install and maintain it, after it leaves the factory and what the service environment is like. Most tanks will far outlive their warranty period, however the Indian Standard requires a design life of 10 years.

Poly tanks are also very strong. If properly designed and manufactured according to Australian standards for poly tanks then bulging and warping should never happen. Some features of a strong and quality poly tank include:

• It being moulded as one seamless piece (that is, without side seams)
• Strong base corners with a radius of 25mm for a tank up to 1.8m in diameter, or a radius of 38mm for tanks over 1.8m in diameter.
• Tapered tanks walls (thicker poly walls at the base of your tank where the most pressure will be)
• Ribs which provide greater strength.

The material can withstand the harsh effects of the Sun due to UV-stabilisers added to the moulding mix. Just like how adding chromium to steel can protect it from rust, so too UV-stablisers being added to a polymer mix prevents the plastic from becoming brittle and decomposing.
