Dual-Flush Toilets: The Facts & Figures

Low flow and dual flush toilets are becoming increasingly common, after legislation in the 1990’s put old water guzzlers to rest. Of course, you will still see them in older homes with original toilets, but new developments all use low flow toilets. But what’s with the dual flush frenzy? In this post, we will tell you all about them and show you why you might want to consider installing dual flush toilet, or convert existing toilets in your home to dual flush models.

The basic principle behind a dual flush toilet is to save water, because, well…. sometimes you just need a lot less water than other times. By having the option to choose just how much flushing is needed, you can save around 25% on your water bill, and the environment will thank you for it. Sounds like a good deal, right?

Some people have asked just how much difference the two separate flushes make and studies have showed fascinating results: Compared to a conventional toilet, a dual flush system can reduce water consumption by up to 67%.

There is so much merit to the studies, and the advantages of using these systems, that countries have passed laws that require all newly installed toilets be dual flush systems in order to conserve the dwindling water resources around the world.

Dual Flush Technology

Dual flush toilets have reached an industry boom and developers are working hard to make the toilets more beautiful , simple to use and comfortable as possible. There are many styles to choose from, and various flushing mechanisms. Some models have two buttons, which are preferred over the push or pull models. The button models drastically cuts down on miss-flushes.

A dual flush toilet looks pretty much the same as any other toilet, except, there are two flushers. The one flusher uses about .8 gallons, and is recommended for liquid waste, whereas the 1.6 gallon flush is for solid waste.

Some research has shown that a dual flush toilet uses around 4.8 gallons of water per day in total, compared to standard old toilets that use 3.5 gallons per flush, and 8 gallons per day in total.

Of course, due to the reduction in water usage, you will see significant water savings when you install a dual-flush toilet.

Costs of Installing a New Dual Flush Toilet

Of course, if your toilet is in perfect working condition, you don’t necessarily want to fork out money on installing a new one. However, there are numerous options available for you to reap the benefits of a dual flush toilet while still using your same old toilet, for example:

1. Fill a half-gallon plastic container with sand or pebbles, and sink it into your toilet tank. It will prevent the toilet from filling up with as much water, and you should save half a gallon per flush.

2. Speak to your local plumber about converting your existing toilet into a dual flusher. It is quick, simple and affordable.

The only drawback to dual flush systems is that the plumbing required for installing an new dual flush toilet is a lot more complicated than the average toilet. It’s not recommended as your weekend DIY project!

Great news for homeowners, is that all toilets will soon be dual flush and the old gallon-guzzlers will be a thing of the past.
