With more and more of us finally becoming eco-conscious, modern dual flush toilets are a great way to cut down water usage and save energy.

If you’re anything like us at Victorian Plumbing HQ, you’ll have been putting more thought into being that bit more environmentally friendly.

Shallow baths, shorter showers and taps off when brushing teeth. All of these little habits go some way to saving substantial amounts of precious water, as well as the energy it takes to provide it.

However, most of us pay very little attention to another thirsty bathroom fitting; the toilet.

Yes, you read that correctly. The common household toilet is one of the main offenders when it comes to water wastage.

If your toilet isn’t a dual flush toilet, that hygienic flush after every bathroom visit could be using up to 13 litres of water every single time that you activate it.

Assuming everyone visits the bathroom more than once, this could quickly result in an average toilet using in excess of 100 litres of water per day for a family of four.

This quickly adds up to a startling amount of water and could even be having an impact on your water bill!

Luckily, there’s a simple way to significantly improve the efficiency of your toilet.

 

What is a dual flush toilet?

Simply put, dual flush toilets are the same as regular toilets but with an innovative dual flush valve installed which gives the option of a full flush or a half flush. Giving you the option to choose the flush that you best see fit, allowing you to use half the amount of water wherever possible.

 

The Benefits of Dual Flush Valves

There are a number of benefits to owning a dual flush toilet which will really make your investment all the worth while.

  • Dual flush valves can substantially cut your water use by using just enough water to adequately flush your toilet. This is achieved by allowing you to choose whether to use a full flush or a half flush. Which means that you will only use 3 litres of water instead of 6!
  • Using half the amount of water when you flush can help to bring down the water usage in your home, which can really help to improve your environmental impact.
  • Another benefit to a dual flush toilet is that you will notice that your water bills will be lower. A toilet uses the most amount of water in your home, therefore using less water will see an impact on your water bills.
  • Unlike a standard toilet which relies on a pressure syphoning system to carry out a full flush, a dual flush toilet typically relies on gravity. This design means that the toilet is less likely to become blocked, meaning you won’t be seeing much of that dreaded plunger.

Do I Already Have A Dual Flush Toilet?

Many of you may actually own a dual flush cistern or dual flush toilet already without knowing about it! If your toilet was installed within the last 20 years, chances are it is a dual flush toilet.

How can you tell? If your toilet’s flush push button has two options or can be flushed by lifting its handle up as well as pushing down, it’s highly likely you’re dual flush ready! If not, read on for a look at our favourite dual flush toilets.
