Choosing the right water storage tank for any domestic or industrial need is a crucial decision. In order to make the wisest choice, here are 5 important factors that you have to consider:

  • PRICE – Price should never be way beyond your budget.
  • SIZE – Pick the size depending on how much space there is on your site.
  • DURABILITY – Make sure that the tank will last long to get your money’s worth.
  • MATERIAL – Choose the appropriate material for your tank depending on your site’s location.
  • AVAILABILITY – Lead time for small tanks ranges from 3 to 7 days. For bigger tanks, it will take 21 to 30 days.

Our lead time for small units (2,000 liters and below) is seven working days on a maximum. For bigger units above, maximum of 14 working days.

We produce premium water storage tanks of different types and configurations with sizes and volume capacity ranging from 240 liters and up.

For a water tank to function to its optimal level, it is important to understand the correct maintenance that it requires. Note that it is important to inspect your tank at least every 6 months. Here is a list of areas that you should check out:

Tank and tank roof

  • Any holes or gaps should obviously be repaired.
  • Check for the presence of accumulated debris, droppings, and other foreign objects.

Inflow and overflow screens 

  • Accessories must be properly cleaned and secured. Repair if necessary

Internal inspection

  • All access points must be properly sealed.
  • Light entry should be fully blocked.
  • Remove any blockages from the first flush device as necessary.

Fittings, pump, main switch, and pipes

  • Make sure that all of these are fully functional.

Water storage tanks should be cleaned and disinfected a minimum of once a year. The rule of thumb is to do it whenever your water supply tastes, looks, or smells unusual.

Water tank fittings guarantee that you’ll get the best set-up and installation of your tank. Firstank offers a wide range of superior quality water tank fittings and accessories to ensure the most effective use of your tank. Critical water storage accessories such as filters, brass outlets, gate and ball valves, hose and tap accessories, and other fittings are also available.

Magnetism is the most common testing method to identify if the material of a water tank is indeed stainless steel. However, this method is already outdated and inaccurate. Firstank recommends these 2 methods, instead:

  • Nickel Content Test – Type 304 stainless steel is an austenitic T 300 Series Stainless Steel. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon.
  • Lab Testing – The simplest chemical test to distinguish carbon steel from a stainless steel is to apply a drop of nitric acid. The carbon steel will react; the stainless will not.

To ensure that you’ll get a 100% real stainless steel, your best bet is to simply purchase premium water storage tanks from a brand with a reputation for good quality. Case in point, Firstank.
