Toilets are one of our most used home appliances and demands special consideration when choosing one to fit our needs. When you are first shopping for a new toilet, you should consider its flushing system. Most systems are either siphonic jet or gravity-fed, but which option is better?
Siphonic Jet Models
Table of Contents
You can see siphonic jet units in most households because they have a distinguishing S-shaped trapway that connects the bowl to the home plumbing system. With a specific “siphon” method that moves the waste down the tubing, and a big water surface and high water level, these have become a standard model used everywhere.
How Do Siphonic Jet Toilets Work?
When you press the flush button, water gets released from a tank and enters the bowl. This is why the water first rises and then quickly goes down, taking the waste with it down the pipe. During this process, water entering the bowl comes in faster than it can retreat, creating a powerful vacuum, which rarely leaves any trace of waste behind.
How Much Water Do These Toilets Use?
It all depends on the model, but on average, siphonic jet toilets use around 4 gallons of water per flush. However, according to new water usage laws, toilets are not allowed to use more than 1.6 gallons of water, which is why most manufacturers had to re-design the way their models work.
Why Should You Buy a Siphonic Jet Toilet?
The first thing that should be mentioned about these toilets is that they rely on high water levels to function. This not only helps keep any odors and gases trapped, but its powerful flush means you spend less time cleaning. If you are wondering if its operation makes a lot of noise, don’t worry – siphonic jet toilets are usually pretty quiet.
Gravity-fed toilets are quite popular in Europe and are slowly gaining popularity in the United States, too. These models are an excellent option since they conserve water and help to reduce monthly water bills. Gravity-fed toilets are also eco-friendly, which is another big plus.
How do Gravity-Fed Models Work?
Obviously, these toilets take advantage of gravity to aid the flushing process. Although it might sound complicated, the working principle is quite simple. When you press the flush button, the water is released from the tank which then passes through the bowl. These models have straight trapways that use water to create enough gravitational force to thoroughly remove matter quickly. Due to this design, these toilets rarely get clogged.
Do Gravity-Fed Models Save Water?
Unlike siphon jet toilets, these units are designed to minimize water waste. Most units feature a dual-flush design, which gives you the choice of either 0.8 or 1.6 gallons per flush. This ensures you don’t have to empty the whole tank for liquid waste.
Why Should You Buy a Gravity-Fed Unit?
Besides minimizing water wastage, these toilets are also small and ideal for compact bathroom layouts. Even better, clogging these models is virtually impossible, which is another significant advantage compared to other models. When it comes to the price difference between the siphonic jet and gravity-fed units, it mainly depends on the style and features you prefer.
Siphonic Jet vs. Gravity-Fed Toilets: Pros and Cons
Obviously, both types of toilets have their pros and cons, but we couldn’t pick an exact winner since they are good in their own specific segments. For example, siphonic jet toilets have a very powerful flush that leaves the bowl perfectly clean. They are also much simpler to maintain and are pretty decent at preventing odors. On the other hand, these toilets are also prone to clogging and usually take up a bit more space in your restroom. Finally, these toilets do use much more water than gravity-fed toilets.
Gravity-fed models are almost impossible to clog and do save water. These toilets are also more compact and lightweight compared to siphonic jet units, which makes them ideal for smaller bathrooms. But, they are not so great at preventing odors and can also surprise you with unsightly waste streaks in the bowl.
Obviously, the choice between these two types of toilets depends mainly on your needs. Be sure to carefully check their pros and cons and clarify what exactly you prefer in a commode. Also, never choose the cheapest unit – although it might look tempting, buying a high-quality toilet is a much better long-term investment.
