Details comparison Dual Flush VS Single Flush Toilets

Flushing system

The main difference between the single flush and dual flush toilets is how they push waste down the drain. Single flush systems use one type of flush to clear waste from the bowl. It doesn’t matter if its liquid or solid waste, the same amount of water will be utilized. Most of the latest single flush systems use 1.6 GPF or 1.28 GPF. On the other hand, old toilets use at least 3.0 GPF to get rid of waste.

Dual flush toilets have two types of flushes to choose from. One is a partial flush for liquids, and the other is a full flush for solids. In most cases, the partial flush uses 1.0 GPF, while the full flush uses 1.6 GPF. To access the dual flush, most toilets have two buttons on top of that tank that you have to press to flush the toilet. Alternatively, single flush systems come with a lever that is easy to activate.

Water usage

Single flush systems use more water than dual flush systems. This is because they only have one flushing option, which is the same amount of water for eliminating liquid and solid waste. On the other hand, dual flush systems are eco-friendly as they provide two flushing options. Some single units use even more than 3 GPF, which dual flush systems use 1.6 GPF or less.

As a result, installing a dual flush system will lower your water bill and may help you get rebates in some states. But if you want a powerful flush, regardless of whether you save water or not, then you should consider picking the single flush toilet.

Modification

When it comes to aesthetics, then you can never go wrong with the single flush system. Unlike buttons found on top of dual flush toilets, single flush toilets come with a trip lever. This allows you to modify it to blend with your bathroom décor. You can install a chrome trip lever with a chrome finish or any other finish of choice. Of course, you cannot do this with the buttons on top of the dual flush toilet.

Maintenance

Maintaining a dual flush toilet is not as easy as maintaining a single flush system. Dual flush toilets are still new to the market, and finding their spare parts is quite challenging. That’s why some people have not embraced them yet at the moment. Single flush toilets have spare parts all over. So, maintaining them isn’t an issue at all.

Versatility

Single flush toilets limit the user. Whether you want to flush liquid waste or solid waste, you will still use the same amount of water.  But for dual flush units, there is a partial flush for liquids and a full flush for solids. So, the right amount of water is utilized for different purposes. As a result, a dual flush toilet is more versatile when compared to a single flush toilet.

Eco-Friendly

Not all toilets are eco-friendly. With water becoming scarce, it is essential to preserve it. That’s why some states in the country have introduced rebates so that people who install water-efficient toilets are rewarded. Most dual flush toilets are water-efficient as they use less than 1.6 GPF. Others even use less than 1.0 GPF. With the new technology, toilets still flush efficiently even with less water.

The problem is that most single old toilets use 3.0 GPF or even more, while the latest single flush toilets use 1.6 GPF or 1.28 GPF. If you want to save water, choosing a dual flush unit is the best choice.

Price

Kohler toilets are cheaper than Toto. This is understandable as Toto is the leading toilet brand in the world. Also, it boasts some of the best toilet technologies in the world. So, if you want a reliable and dependable toilet, you should be ready to pay more to get a Toto toilet.

Final Decision: Dual Flush or Single Flush Toilet?

Now that you have knowledge about single and dual flush toilets, it will depend with what you prefer. If you are more concerned with your bathroom aesthetics, then the single flush toilet is the best choice. But if you want to save water, then you’re better off with the dual flush toilet.
