If you have an older bathroom with a single flush toilet, then you might be keen to switch to a dual flush alternative. With a single flush toilet, you literally throw water down the drain. A dual flush toilet will reduce your water waste and your usage charges.
These toilets give you the option of using one of two flushes. They have a half flush that can easily deal with liquid waste and a full flush for solids. If you have this kind of flush mechanism, you reduce the amount of water you use in the toilet with whichever button you press.
While any dual flush toilet will be more efficient than your current model, you should put some thought into any planned upgrade to see the best savings. What do you need to know?
1. Dual flush toilets aren’t all the same
While toilets all do the same job, they don’t all have the same levels of efficiency. Some dual flushes give you better water-saving capabilities than others.
Typically, you measure the efficiency of a toilet by a rating given by the government-led Water Efficiency Labelling and Standards (WELS) scheme. The WELS rating tells you exactly how well a toilet can perform.
This scheme works in two ways. First, it gives every toilet an efficiency rating in stars. So, you can immediately see that a 3-star rated toilet will perform less efficiently than one with a 4-star rating. The higher the rating, the more efficient the toilet will be.
Second, the rating also tells you three key figures about the water that the toilet uses when it flushes. You can see how many litres it uses in a half and full flush. You also get an average flush figure.
Again, this information helps you shortlist the best toilet. The less water a toilet uses in any of these flushes, the more water-efficient it is.
Your choice of toilet essentially dictates how much water you can save. To get optimum efficiency, use both these WELS ratings. Look for a higher number of stars and lower flush statistics.
2. Dual flush toilets need your help to work completely efficiently
Even if you install the highest-rated dual flush toilet in your bathroom, you only maximise your water savings if you use the flush correctly. This kind of toilet automatically uses less water than a single flush unit even on its full setting, but you have to use the flush correctly to maximise your savings.
So, you and anyone else who uses the toilet should understand what each button does and when to use it. Ideally, you’ll get into the habit of only using a full flush when you actually need to.
You can make this easier by looking at toilets that have separate flush buttons. These panels typically have one small and one large button kept apart to make things clear. If you buy a toilet with one button split in half, then you might find it harder to select the flush you want to use every time.
3. Dual flush systems can work in existing toilets
If you aren’t ready to install a new toilet right now, then you might be able to convert your existing toilet to a dual-flush system. You can retrofit these flush mechanisms into some toilets.
Here, you basically replace your toilet’s flush mechanism with a new one with dual controls. This option doesn’t work on every toilet and might not save as much water as a new toilet would; however, it will reduce your usage.
If you want to install a dual flush toilet, then contact plumber Killara Andrew Vanny Plumbing. We can help you choose and install the right model for your needs. We can also give you advice on whether you can retrofit the toilet instead if you prefer. If this is feasible, we can then convert your system for you.
