Hard water and soft water are different ways in which we classify water. The names ‘hard water’ and ‘soft water’ come from what’s in the water. For example, hard water is water that contains high amounts of minerals and metals like magnesium, calcium, iron, zinc, manganese, etc.

Water naturally contains some amount of minerals in it, which is healthy for us to consume and use. However, when too much of these minerals and metals are present in it, that water can be hazardous.

For that reason, best Twin Tank water softeners were developed. These machines remove the excess of minerals and metals from the water and make it safe (soft water) for us to use.

Single tank water softeners are suitable for small families. However, if you live in a large household and want a soft water supply at all times in the day, then the twin tank water softeners are more suitable. That said, it is vital that you choose a good quality twin tank water softener. Poor quality ones break down quickly and have frequent problems.

We know it can be overwhelming to choose from so many options available on the internet. For that reason, we have put together this 8 best twin tank water softeners in Australia list. Our recommendations are based on in-depth market research, a critical analysis of each twin tank water softener, brand reputation, and customer reviews.

Complete Buying Guide on the Best Twin Tank Water Softener

Best Magnetic Water Softeners in Australia Buying Guide

Twin Tank Water Softener – What is it?

As the name suggests, a best twin tank water softener in Australia comes with two tanks instead of one. In the twin system. Instead of one tank softening your water, two tanks do the needful. The two tanks take turns to soften your water and remove hard minerals and metals from it, making the water safe and healthy for you.

Two understand how the twin tank water softening systems work, it’s helpful to understand how the single tank system works. In this single tank system, the softener goes through a down in order to regenerate. All softeners, whether high quality or low quality, need to regenerate after each softening cycle.

When the softener is in its downtime mode, it won’t be softening any water. So, it may happen that you may not have soft water during that time unless you have previously stored some of it. On the other hand, in a twin tank water softener, when one tank is regenerating, the other one is working to soften the water. And then, when the second one is on the downtime, the other one is softening the water.

For that reason, the twin tank system ensures that you have soft water 24/7 and at all times in the day. Due to their two-tank system and because they give you a continuous supply of soft water, twin tank softeners are an upgrade to the existing single tank systems. Twin tank softeners are suitable for those who have a severe hard water problem and need to protect their pipes and water appliances.

Because twin tank softeners have two tanks and advanced technology, they cost much more than single tank systems. However, their high price makes it up in the long run as you will have soft water at all times.

With the single tank systems, there is still a chance that the pipes lines and water appliances can be damaged. This is because hard water will flow through them during the downtime/regeneration period of the softener. But with the twin tank systems, you won’t have to worry about any of that. Because you will have a continuous supply of soft water, your pipes, your water appliances, and your family’s health, all will be protected.

How Does A Twin Tank Water Softener Work?

Twin tank water softening systems work similarly to the single water softeners with just one simple advancement. It’s the same process – the water enters the softener where the resin beads are present. The resin beads contain salt ions. When water flows through the beads, the salt ions take the place of the ‘hardness ions’ in the water, replacing them.

Once the salt ions take the place of the hardness ions in the water, the hardness ions get stuck to the resin beads. The water softener process is simple, the hardness ions present in hard water get trapped in the resin beads. And the salt ions previously present in the resin beads take the place of the hardness ions (excess minerals and metals), giving you water free from the hard minerals and metals.

The hardness ions are now in the resin beads instead of the water. The resin beads are full of hardness ions. Once the softening process is over, the system needs to clean the hardness ions to get ready for the next softening cycle. This is when the system goes into downtime and begins the regeneration process. In the regeneration process, the hardness ions are flushed from the resin beads and out through the drain.

The regeneration process involves the straining of brine water into the water tank and which then proceeds to remove the hard minerals from the resin beads and then flush them out of the drain. Once the resin beads are free from the hard minerals, the soft water then cleans out the remaining brine water. The softener is then all set for its next softening cycle.

The regeneration process is crucial for the softener to work optimally. Without the regeneration process, the hard minerals will be stuck in the resin beads, and there will be no more space for more hard minerals that come from the next batch of hard water. Since there will be no space for more hard minerals in the resin beads, the softener will not be able to softener the water anymore.

But with the twin tank system, while one tank is regenerating, the other tank will soften the water and vice versa. And so, you will never face a lack of soft water. You will not have to wait for soft water while one tank is regenerating, as the other tank is all set for a new cycle of water softening. The water tanks automatically switch the flow from one tank to the other while the other one is regenerating.

Frequently Asked Questions on Twin Tank Water Softeners in Australia

What Do I Need To Consider While Buying The Best Twin Tank Water Softener?

Water softeners, whether the single tank or twin tank ones are a huge investment. Good quality best twin tank water softeners in Australia last for more than 20 years and require very little maintenance. If you’ve come to the conclusion that you, in fact, do want to invest in a dual tank water softener, then the next step is to choose the right brand and model for your specific needs and preferences.

Here are a few important factors to consider if you want to buy the best twin tank water softener in Australia for yourself:

What Are Your Needs?

The first and one of the most important steps is identifying your needs and the purpose of buying a water softener. Yes, if you already know your water is hard and contains an excess of metals minerals, then you definitely need a softener. However, it’s also important to know the level of hardness of your water supply. Knowing if your hard water has high levels or low levels of metals and hard minerals will help you choose the right water softening system.

If your hard water problem is not that serious, then a single tank water softener may also work. But if your hard water problem is severe or if you have a big property or family to supply water to, then a twin tank softener is ideal. To know if you have hard water and the seriousness of the hard water problem, you can send your water to a nearby lab for testing.

These test results will reveal the quantity and types of hard minerals and metals present in your water supply. When you know the level of your hard water problem, it will be much easier to know which water softener will work best for you.

What’s Your Budget?

Another important factor to consider is your budget. Twin tank softeners are available in a wide range of prices. You will find budget-friendly and affordable softeners that cost a couple of hundreds. And you will also find high-end twin tank water softeners that cost more than a thousand dollars.

Knowing your budget and how much you are willing to spend on one of the water softening systems can help you make the right choice.

Flow Rate

The flow rate of the water softener is an important factor to consider so you can buy the one that suits your needs the best. The flow rate is the speed at which the softener can supply you with soft water every minute. The flow rate is calculated using the gallons per minute (GPM) measurement.

For a small household, water softeners that can provide a flow rate of 7 GMP to 22 GMP are suitable. For larger households, restaurants, or bigger properties, softeners that can deliver a flow rate of 22 GMP at least and higher are ideal.


Another important factor to consider is the quantity of water the best twin tank water softeners can handle in one softening cycle. In other words, how much quantity of water the system can handle before the regeneration cycle. The more water the tank can contain, the better it is for the water softening process.


Maintenance is another important factor you need to consider. Some water-softening systems require a lot of maintenance, while others require very little or absolutely no maintenance from your side. Water softening systems regenerate automatically, so you don’t need to do much.

But you will need to add salts to the resin beads when the salts are over, or sometimes you will have to put new resins in the softeners. Different models might also need different types of maintenance. So to ensure a smooth experience with your softener, ensure that you consider the maintenance aspect, including the costs.


Many people tend to ignore this factor, but it is a highly important one. When you buying a certified best twin tank water softener in Australia , you can rest assured that it is made from high-quality materials, is durable, and completely worth the investment. Certified softeners are thoroughly tested before they are approved. So ensure that you buy a twin tank water softener that is certified by WQA or NSF/ANSI.


With a single tank softener, you often have to wait for the tank to regenerate before you can get soft water again. Having to wait while the single tank softener is in downtime leads to time wastage and unnecessary hurdles. A twin tank water softener will ensure that you have soft water at all times without having to ever wait.

We hope the 8 best twin tank water softener in Australia list we have provided you with above has given you enough quality options to choose from. And we also hope our extensive buying guide has given you the right information to help you chose the best twin tank water softener.
