Your water tank’s first line of defence against corrosion and internal damage is the liner, so it naturally stands to reason that you should be making an effort to ensure that it’s in good condition and replaced at the earliest convenience when necessary.
Water tank liners can last quite a long time, but as with many components they do have a lifespan and will wear out over time. Before relining your water tank, consider doing the following:
Inspect for Signs of Damage
Water tank liner damage can come in many forms; many are obvious, many are not. Visible signs of damage can include anything from cracks or tears to peeling or punctures. These are sometimes caused by abrasion from the liquid held in the tank (if not water), sediment buildup, or from acute impacts. They could also simply become evident as the liner begins to wear out.
You may also notice that the tank’s capacity is not where it should normally be, or that leaks are visible. If your tank isn’t holding as much liquid as it should, it could be from a small puncture. Wrinkles, sagging, or cracking/peeling can also be a consequence of an ageing water tank liner. UV ray exposure can also accelerate the ageing process and deteriorate the liner sooner than anticipated.
Lastly, one (often) less obvious immediate sign of water tank liner damage is if the water has a strange taste or colour. If the water’s appearance (or other liquid) is not as it ought to be, it could be from leaching. The liner is supposed to protect against leaching, but if worn out, the liquid could be leaching metals from the bare tank.
Consider Relining the Tank or Replacing the Tank Altogether
If a water tank liner is in need of replacement, it may sometimes be more beneficial to replace the tank altogether. In most cases, relining the tank is faster, easier, and more cost-effective, however, so weigh the cost of both options but also consider the condition of the tank itself. Relining a tank with severe structural issues might end up being a waste of resources.
The tank’s insulative properties and internal temperature (when it must be controlled) can be vital and relining the tank may be essential for certain industrial applications, so time is of the essence when a water tank needs to be relined or replaced.
Generally, water tank relining is the preferred option for tanks that are otherwise in fine condition. If the tank has been neglected or is in poor condition, consult with water tank experts in Sydney for cost-effective alternative solutions.
Choosing the Right Water Tank Liner
Replacing a water tank liner, if that is the preferred option, comes with other considerations. Firstly, the type of material used should be adequate for the stored liquid, water or otherwise. PVC, polyethylene, and other synthetic materials all have material qualities that may make some more appropriate than others depending on the application.
Next, the liner must be of sufficient structural rigidity and durability to withstand physical forces within the tank as well as chemical properties of the stored liquid.
The liner must also satisfy regulatory compliance where necessary, whether it be for potable water that is deemed fit for consumption or liquids with carefully measured solutions of specific quantities.
Lastly, it is essential to select a qualified water tank company in Sydney such as Tank Vision to ensure that the water tank relining is conducted properly.
