Dual flush toilets are designed to reduce the amount of water flushed during every use. This is interesting because regular flushing can potentially waste tons of water over a long period of time. Not only is it wasteful for the environment, but it also affects your monthly water bill. 

These types of dual-flush valves have two different buttons for the two possible types of downloads: one for liquids, and one for solids. According to studies, this system can help to save water used in flushing, which also saves you money. Here are other reasons why you should consider a dual-flush valve installation!

How does it work?

When you use the liquid discharge button, it means that the toilet will perform a less powerful flush, since less water is required for this process. The solid discharge will perform a flush with more water (about three times more), but also in a more controlled manner.

This is different from the typical valve where you hold and it only stops flushing once you let go – which throws a lot of water down the toilet… no pun intended.

The use of gravity rather than siphoning also helps in reducing the waste of water while ensuring you only have to flush once.

Dual flush toilet with coupled box

The coupled box is most commonly used because the hydraulic system is simpler, with pipes that can be branched and that have a smaller diameter than the flush valve used in conventional toilets.

There are also several models of different colors, sizes, and styles, which allows you to combine the toilet with the rest of your bathroom decor. If you don't want the external box, there are boxes that can be built inside the walls for a more minimal appearance.

The best dual flush toilet is mostly a matter of personal preference when it comes to design because if they’re well installed, they will always perform as they should!

Dual flush toilet with built-in box

Toilets without a built-in box use a flush valve that is on the wall, which connects the water from the water tank (or the network) directly to the toilet.

One of the advantages of this system is that it allows the entry of water with pressure, making it far more likely that the waste is cleaned with a single flush. It also makes for a concealed design that fits well inside modern bathrooms.

The only downside is that the installation process might take longer and require more planning, but the result is a very slick design.

How much money and water does it save?

Dual flush toilets save about 67% of the water used compared to regular toilets. Yes, more than half as much as regular flushing.

In regular restrooms, 1,000 gallons used can range from $2 to $3 in charges, as the average person flushes 20.1 gallons of water a day, the amount can be absurd in the end. Dual flush ones use even less. Typically, the solid waste button will be flushed regularly (1.6 gallons) and the liquid waste will only use half the amount of water (0.8 gallons). 

Besides, you don’t have to purchase an entire new toilet for this, you can simply replace the valve for a dual-flush and keep your regular toilet as is.

Other ways to save water

The toilet isn’t the only place where water is commonly wasted. Whether you want to be more conscious of the environment or simply reduce your water bills, here are other things to watch out for:

  • Don’t leave faucets running while you do dishes or brush your teeth
  • Watch your plumbing for leaks and fix them immediately
  • Only run your washing machine or dishwasher once they’re full
  • Gather rainwater to use around the house (as long as it’s not for drinking)
  • Mind your time in the shower
  • Replace your shower head with a modern version

Now that you already know the features of a dual-flush toilet and a few other tips, you can start thinking about installing one in your home. It will make your life easier and help the environment by saving water, which is far more valuable than we give it credit for.

A local plumber can easily help you install a dual-flush valve and help you with other ways to save water around the house.
