Frequently Asked Questions

What size water tank will I need?

The size of your poly tank will depend on various factors, including the amount of rainfall where you live, the size of your catchment area or roof, and how you’re intending to use your tank. Generally, experts will recommend the largest tank you can fit so that you can maximise the benefits you gain from your new system.

Once you have an idea of the answers to these questions we can discuss your needs with you and decide on the type of tank that is ideal for your property. Before this you can also explore our range of poly tanks available in Coffs Harbour online.

How long can I expect my tank to last?

All our tanks are top quality, made in Australia specifically for Australian conditions. Warranties range from 5 to 20 years depending on the brand that you choose.

The lifespan of a poly tank can be influenced by many variables, including the material being stored, its concentration, the level of sunlight and UV rays, and the temperature. Some other common factors include:

  • Installation: Improper installation is the main contributing factor to tank failure, and it’s crucial your pipe work is designed and installed properly, with allowances for the expansion and contraction of the tank, strong support for your pipes, and fittings that can reduce stress on the tank.
  • Storage: A tank that’s continually cycled or that undergoes excessive agitation will experience more stress than one that stays level for longer periods of time
  • Chemicals: Some chemicals can impact the lifespan of your poly tank, as they can lead to a build-up of sediment as UV exposure and rising temperatures cause them to break down. Flushing out this sediment from your tank will improve its lifespan.

Why should I consider buying a poly tank?

With the strong potential for drought in Coffs Harbour and across the Northern Rivers, water conservation is essential where possible.

Storing rainwater for use around your home, property or commercial site is a cost-effective, efficient way to recycle this precious resource.

Some properties are not connected to mains water, and in these cases rainwater’s a fantastic solution to ensuring you have clean water available. If you are connected to a main, you’ll have the flexibility to use tank water whenever and wherever you like.

Our poly water tanks are a valuable addition to any home or property, and with the range of sizes and colour options on offer, you’re bound to find a product that suits your needs. Get in touch – our team would be happy to assist with all your rainwater tank needs.

Can I drink water from my poly tank?

At North Coast Power & Water, we stock tanks made from food-grade polyethylene which are designed to hold drinking water. Some local governments or water authorities may prohibit you from using rainwater for drinking, cooking, and washing.

If you are not permitted to use rainwater for drinking, your water can be filtered and treated to make it safe to consume. If you’d like to install a rainwater tank to hold drinking water and are unsure of your options- we can assist you.
