As a plumber, we are often asked a number of toilet related questions by clients. Something that often pops up is what type of flush do I recommend? Well, there isn’t an easy way to answer this, as a lot of it depends on your household and current plumbing system, but from the point of view of saving water, dual flush toilets are great. Read the following guide for more information:

Why are dual flush toilet more efficient than single flush?

As mentioned above, the main advantage dual flushing mechanisms have over their single flush competitors is the ability to save water. Single systems use the same amount of water no matter what the situation or type of waste is. And more often than not, this is a higher quantity. This is great for those wanting power and performance alone, but from the conservation point of view, it’s not as effective.

Dual flush mechanisms offer you two options. Option one, a full flush that shares similarities with single flushes, or option two, which is a partial flush. This is where these toilets save water. You don’t need to use much water to get rid of liquid waste from the bowl. And as that’s the most common type of waste households deal with, it can save a significant number of gallons per year.

We’ve picked out a couple of our favorites below.

Kohler Highline

The Highline collection is beautiful. From a purely external aesthetics point of view, it’s one of our favorites. The simple two piece design adds a touch of elegance to the bathroom and the elongated shape bowl provides important support. But what we’re really interested in is the inner mechanisms.

It’s quite easy to miss gems like this because you need to dig below the surface to really understand its capabilities. For example, it’s not widely advertised that this is class five flushing performance. The likelihood of the toilet getting blocked up is very low because of this.

And if you need a bit more power and performance to give the bowl a really thorough rinse, you can switch from the lighter 1.1 gallon flush to the 1.6 gallon one. The beauty of such a system is that it saves consumers up to 20% more water every year.

The toilet seat is included, and it has a 2-1/8 inch fully glazed trapeway. It will work well as a 12 inch rough in installation, and because Kohler attach 3 bolts to the tank, fitting everything becomes less time consuming.

American Standard Cadet 3

We are fully aware of the fact that many people will not have a big budget to work with. That’s why we always try to include toilets that are cheaper than average in our lists. And that’s exactly what the Cadet 3 is. A low budget alternative from a reputable manufacturer.

Like the Highline, this is a two piece toilet. The separation of tank and bowl can have its issues, but getting one from the right company removes this worry.

The dual flush system uses 1.0 or 1.6 GPF. It matches many of its competitors in this area. However, the additional EverClean coating that is layered on top of the bowls surface creates a slicker surface that prevents bacteria and waste adhering. This will play a role in the products longevity and ensure staining and damage to the ceramic is limited.

There is no need to spend extra on seating either, as the Cadet 3 comes equipped with a slow closing seat.

Editor notes

Both of these toilets have their strengths and weaknesses. We recommend the Highline for those wanting a model with strong performance and comfort. However, the Cadet 3 is a inexpensive option that could excel in most residential environments. Regardless of which you choose, make sure you understand your rough in measurement to ensure it fits. It may also be worth looking into competing brands like Toto.
