Quick tips for choosing a superior plastic water tank

5000 litre jojo tanks

There are so many brands of plastic or polyethylene water tanks available but one should choose carefully to ensure your poly water tank gives good service life and stores the water safely.

Here are some tips to ensure you choose the right poly water tank:

  • Check that the tank carry’s a manufacturer’s warranty or guaranty and ensure that you understand the conditions. You should be looking for a tank that carries at least a 5-year guaranty/warranty.
  • Is the brand of the water tank well-known? Is the brand local or an import? Generally, it is safer to buy a local, well-known brand – you will be able to make use of local after sales service and advice. Imported tanks or ‘no-name’ tanks (sometimes branded with a particular retailer’s logo) are a risky purchase.
  • Is the poly tank rotational moulded in a single piece or does it show seams? Rotational moulded tanks are superior as they do not have seams that could split or crack. Look carefully, some split-moulded tanks have their seams disguised.
  • Is the material made from food-grade, virgin material? If you intend storing potable water for human consumption, make sure that the tank is rated for this purpose. Some cheaper ‘plastic’ tanks are made from polymers that could leach harmful chemicals into the stored water.
  • Is the tank UV-protected? In climates such as South Africa, built-in UV-protection will ensure the water tank does not crack and fade in short order.
  • Is there an algae-inhibiting inner lining? Many poly water tanks are sold without this extra feature which is particularly important in hot, sunny climates such as South Africa. The lining is usually black in colour and helps to lower maintenance sessions (algae can become a nuisance, affecting the taste and quality of the stored water).
  • Does the tank have inlets, outlets and an overflow aperture? Cheap plastic tanks may not have these ‘extras’ but they really should be standard. Having to cut holes in the tank and fit connectors can become difficult, especially if the tank’s walls are very thin.
  • Are there reinforcing bands built into the tank? Beware of plastic tanks without these reinforcements; they are prone to bulging and deformation.
  • Does the tank come with a manhole and lid? Check that the lid can be properly secured. Cheaper plastic tanks often have ill-fitting lids making it difficult to keep debris and insects out.

Buying a good quality poly water tank will mean that you will be paying a slight premium over inferior brands but it will be worth it in the long term. Some of the cheaper plastic tanks on the market barely last a year! We recommend JoJo water tanks which carry an 8-year warranty, have a food-grade inner anti-algae lining and are good value for your money.
