Water Tank Repairs – Central Coast, Mid North Coast & Hunter Valley NSW.


When was the last time you checked your rainwater tank to ensure that it’s not leaking and is in good working order?

With the drought period that we are experiencing in Australia right now, it’s more important than ever to ensure that your water tank is not leaking and losing water. So lets go through the main things you should consider when it comes to leaking water tanks and water tank repairs.

A concrete water tank that needs repairs

Cleaning Your Rainwater Tank

You should clean your rainwater tank every few years or so to remove the build up of sediment that accumulates within the tank. If your tank needs a serious clean – more than simply removing leaves from the surface, you should get advice from a water tank repair professional. Harsh cleaning may cause damage to the tank, so it’s a good idea to speak to a professional first to consider your options. To overcome any minor cracks or residue build up issues, home owners often decide to install a water lank liner inside their tank.

Leaking Concrete Water Tanks

Undertake a thorough examination of your water tank and look for any cracks or leaks. Most cracks on concrete water tanks can be repaired, but you could also look at installing a water tank liner to refurbish your tank. To find out more about water tank liner suppliers and installers in NSW visit, Water Tank Liners.

Discoloured Drinking Water

Dirty coloured drinking water can be caused by a build-up of dirt and residue from a rusted roof. Or, it can be caused from damp leaves in gutters  – you should clean your gutters regularly to avoid leaf matter building up and also remove any debris from sitting on top of the water tank roof.

Water tanks for drinking water should have a filter installed to trap sediment, but if your tank is old there’s probably a good chance the filter may have deteriorated and needs to be replaced. If you are concerned about the quality of your drinking water, have your tank inspected by a professional to get the issue resolved.

Dampness around a Rainwater Tank

Persistent dampness around a rainwater tank might be a sign of a leak. Check to see if the ground around your tank is damp and investigate the cause.

Mosquito Control

Water tanks provide a great breeding ground for mosquitoes. To help prevent this, ensure any openings are covered by mozzie-proof mesh.

Can you repair a rusted water tank roof?

new water tank roof

A metal water tank roof does have a limited lifespan and will eventually need to be repaired or replaced.

One of the common problems that home owners face is that their metal water tank roof becomes rusty. A rusted water tank roof can result in the household fresh water supply becoming contaminated so it is important to resolve the matter as soon as possible if you notice any changes in water quality.

What causes the water tank roof to become rusted?

Home owners in rural and semi-rural locations often have trees nearby which may overhang their tank causing a build up of leaves and silt sitting on top of the roof for long periods of time. This combined with condensation from within the tank can cause the tank roof to deteriorate. The age of the water tank and the type of metal it is constructed from is also a consideration.

Solution to repair a rusted water tank roof

In most cases the best way to resolve the problem of a rusty water tank roof is to remove the old roof and install a brand new roof in it’s place. This solution generally results in the home owner saving money due to the fact that there is less labour and material costs involved than there would be if the entire tank was replaced. New hot dip galvanised trusses that clear span the tank are used to eliminate any posts in the water. Depending on the condition of the water tank it may be beneficial to consider installing a water tank liner at the same time.

Why use a tank liner?

Tank liners are the most cost effective way to resolve problems with old metal or concrete water tanks that have been damaged or are leaking. It is not actually repairing your old tank, but installing a new tank liner inside your old leaking tank.  This saves any major earthworks costs from having to remove a cracked concrete tank or leaking tank and prepare for a new one.

Tank liners are a cost effective 100% guaranteed solution to a leaking water tank. Your pristine water is stored in an Australian manufactured Bartlett tank liner which is specifically designed for the application of storing potable water. The tank liner is placed inside your existing tank and although it doesn’t repair the problematic cracks or holes in your tank, it does provide your water tank with a new internal tank liner protected by a layer of geo fabric which will keep your water fresh and ensures that it remains uncontaminated.

Generally this work can be performed in just one day with the water liner ready for water straight after installation – thus eliminating any down time due to demolishment of the old cracked concrete tank and construction of a new tank. Concrete tanks with poles, concrete water tanks with internal walls can also be addressed. All the original plumbing can generally remain in place with just minor alterations to the bladder tank system.

Not all water tanks can be repaired due to their age and the extent of the damage. The Bartlett water tank liner without UV exposure will last in excess of 20 years in most circumstances. H2o Tanks & Liners would prefer consider things like a new steel water tank roof prior to the installation of the tank liner. If we find that your water tank is beyond repair or you would just like to increase your water tank capacity, H20 Tanks & Liners can supply and install a new Pioneer Water Tank for you in a range of colours to compliment your home.

What Size Water Tank is Right for My Home?


A rain water tank is a great addition to your home. A tank can help reduce your water bills and provides an alternative for when water restrictions are in place. And if you’re a keen gardener a water tank can help keep your garden lush and green. Water tanks can be custom made to suit the space around your home. So how do you decide what size water tank is right for your home?

What do you need to use the water for?

Think of all the things you can use rainwater for to maximise the use of your tank. That way you’ll get the best value from your water tank. You can use grey water for watering your garden, washing clothes and flushing toilets.

Average amount of water used.

This information is available from your water supplier or use the Hunter Water calculator.

Local Rainfall.

You can search for annual rainfall patterns on the bom.gov.au. In areas with variable rainfall you will need a larger tank to hold the same amount of rainfall as somewhere with more consistent rain.

Area of Roof Draining to Tank.

1mm of rainfall on 1m2 of roof area = 1L of rainwater

How much Security of Water Supply do you Need?

Consider whether it is important for you to have a constant water supply or can you cope with some periods without rainwater available?

According to the Your Home website the approximate tank sizes for a household with mains town water and evenly spread rainfall are as follows:Tank from Cessnock Tank Works

Toilet flushing and use on a small garden – 2,000-3,000 L (Target volume)

Toilet Flushing, clothes washing and small garden – 3,000-5,000 L (Target volume)

Whole House water supply – 5,000-20,000 L (Target volume)

If you live in a rural area where the average rainfall is highly seasonal or no mains town water is available, much larger tanks will usually be required.

If you are in any doubt as to what size water storage tank is right for you, contact your local water tank specialist for advice.

For tank requirements and supply in the Newcastle & Hunter Valley region you can contact Cessnock Tank Works or H20 Tanks & Liners. The Australian Government’s Your Home website also offers advice to help create environmentally sustainable homes.

Repairing a Water Tank using a Water Tank Liner

What is a Water Tank Liner?

new tank liner installationWater tanks suffer wear and tear – but those problems can often be fixed quite simply with a tank liner. So what is a water tank liner? A tank liner can be made from a variety of materials, depending on the water tank for which it is needed. It can be inserted inside a structurally sound but otherwise damaged or leaking water tank to dramatically increase its lifespan.

What Problems can Tank Liners be used for?

So long as your water tank is structurally sound a liner can be used to fix a number of issues including:

  • Rusted and leaky tanks
  • Tanks cracked by ground movement
  • Bushfire contamination

 Why use a Tank Liner?

Tank liners are reliable and cost effective. Leaking tanks are costing you money. Using a tank liner is usually far cheaper than installing a new tank. And it is usually a faster solution too. Tank liners are durable and can really extend the life of your existing water tank.

Is it cheaper to refurbish or replace cracked concrete water tanks?


Local Hunter Valley water tank expert Ross Chapman has been refurbishing and repairing water tanks for home owners within our region for over 15 years and has seen it all.

There is no definite answer to this question but over the years Ross has found that in most cases it is much more cost effective to refurbish an existing concrete water tank rather than replace it.

The problem with concrete water tanks is that concrete can be susceptible to cracking due to natural ground movement. A lot of people see the cracks getting larger and more water being present around the tank and immediately assume that they need a new tank. What they don’t realise is that most concrete water tank cracks can be repaired or we can install a heavy duty tank liner to overcome leaking water issues.

Most people ignore cracks when they first appear but as time goes on they realise that they are losing too much water and the ground around the tank is constantly damp which can be a concern for other reasons.

What happens if you do nothing and continue to let your concrete water tank leak?water-tank-repairs-h20

Well it’s no secret that termites love damp conditions and can be destructive, so the last thing you want is water lying around your home encouraging them.

On rural properties water tanks are usually the sole source of water for the home so you don’t want to be wasting precious water and have to pay to get water delivered to your home.

Can all types of water tanks be refurbished?

Most concrete water tanks can be refurbished and repaired. Metal roofs of tanks can be replaced, tank liners installed and/or cracks repaired with specialised products. However when it comes to plastic poly water tanks and old metal tanks it works out more cost effective in most cases to replace the tank than repair.

If you have any questions or want to find out more about concrete water tank repairs you can give local specialist Ross Chapman from H20 Tanks & Liners a call on 0419 628 402 or visit http://www.buildlocal.com.au/listings/rainwater-tank-repairs-h20-tank-liners/

Building a new home – what size water tank will suit your needs?


If you are building a new home you can easily overlook things like the storage capacity of the rainwater tank that is planned for your new home.

At the time of planning a new home most of us think of a rainwater tank as something that we just have to include to comply with BASIX regulations. Since the introduction of BASIX in NSW, new homes are now being designed to use less energy and less water consumption.  We often forget about the real advantages of having a water tank installed when planning our new home because there are so many other things to consider. Given that you will be living in your new home for many years to come it’s worth taking the extra time to consider these things at the time of planning your new home to avoid disappointment later.

The plumbing design in most new homes these days is set up to allow you to store rainwater from your roof catchment area to use for laundry washing, outdoor taps & flushing toilets. Most homeowners that have a water tank installed for these purposes find that their water usage is reduced by 50% or more. Of course it also helps to have water saving shower heads installed in each bathroom which most builders would offer as a standard inclusion these days. new-home-tank

The ideal tank size for a new home will depend on what the home owner intends to use the stored water for.  For instance, if you are considering installing a pool at your new home you can use the tank water to top up the water level during warmer months. Keen gardeners who like to have a green lawn & garden all year round will also need to factor this in to ensure that the tank will suit their needs.

Water tanks come in a range of different sizes & shapes. Aquaplate Bluescope Steel water tanks can be custom made locally in the Hunter Region to suit your requirements or you could choose from a poly tank as both come in a range of popular colours to compliment the style of your home.

On a standard sized suburban block of land it can sometimes be tricky to find the right location to install the tank. There are slimline tanks available that can be positioned down the side of your home to avoid the need to have a large round water tank taking up a significant portion of your backyard.

Before you sign off on your new home plans, do your homework and talk to your builder when planning your new home to ensure that you find the right water storage solution to suit your individual needs.  If you are using a project home builder you may find that they do not offer the tank size or shape that you are after due to constraints from their supplier.  If this is the case it’s worth talking to them about the possibility of you sourcing the tank yourself elsewhere.

The cost to upgrade the tank to a larger capacity upfront will be insignificant when you consider the long term benefits such as the reduction in water usage bills over the coming years.

If you require further information talk to your local council and/or a professional rainwater tank retailer for more detailed information about the design and installation requirements of rainwater tanks in your area.
