What is a Siphonic Jet Toilet and How Does it Work?

A siphonic jet toilet is a toilet that is designed in such a way as to create a siphon to jet the water out of the toilet and leave it as clean as possible. This is accomplished by the reverse P- or S-shaped traps used for their drains which force the suction of the water — and waste — out of the bowl and into the sewage lines of your home.

This happens because due to the special design, the tank empties faster than the water can take the waste out of the water which forces the water in the bowl to rise. This rise in bowl water level then forces the air in the special traps to then suck the water out of the bowl and siphon the wastewater into your sewage mains.

This type of toilet has been rising in popularity in recent years due to its ability to get the waste out of the toilet bowl as cleanly as possible.

What is a Gravity Fed Toilet and How Does it Work?

A gravity fed toilet, as the name might suggest, uses the power of gravity — and the weight of the water in the tank — to force the wastewater out through the trap. A popular toilet choice in Europe and gaining popularity in the US, gravity fed toilets utilize a specially shaped wide and nearly straight trap.

When the tank is then released, the water exits into the bowl very quickly and nearly all at once. This causes the wastewater to be forced into the trap due to the weight and volume of the rushing water displacing the wastewater that’s sitting in the bowl.

The large traps used in gravity fed toilets are very difficult to clog, so more and more people are starting to choose them over any other type of toilet for the added convenience.

Siphonic Jet vs. Gravity Fed Toilet: What Are the Differences?

Now that you know the basics, let’s take a deeper dive into their differences.

Water Usage

One of the big differences between the two toilet types is the amount of water that is used.

Gravity fed toilets are known for their water-saving capabilities due to using the weight of water — much heavier than air — to force the wastewater out of the bowl. Since it has all the extra energy due to the water rushing down into the bowl, a much smaller amount of water needs to be used.

It is commonly accepted that a siphonic jet toilet will use about twice as much water as a gravity fed toilet.

Clogging

Another category where the gravity fed toilet shines is when it comes to clogging.

Due to the incredibly large and wide-open design of the trap combined with the power of the water, gravity fed toilets are very difficult to clog.

Luckily for siphonic jet toilets, they also do very well in terms of clogging due to how much force the jet of water has as it’s siphoning the wastewater out. That said, due to the narrower trap, they are slightly easier to clog.

Space Savings

Since gravity fed toilets are much shorter and much more narrow, they are also smaller in stature and will take up far less space than a siphonic jet toilet. The bowl on the siphonic jet toilet needs to be bigger to be able to accept the much higher water level that comes to fruition while the toilet is being flushed.

Noise Levels

When it comes to the noise level of the flush, siphonic jet toilets take the cake. Although there is the sudden rushing of air as the siphonic jet clears the toilet out, it is less noisy than the rushing of water slamming into the bowl that you’ll be faced with while using a gravity fed toilet.

In either case, you might opt for soundproofing your toilet room if noise is an issue.

Bowl Cleanliness

Siphonic jet toilets are also the far better option when it comes to the cleanliness of the bowl, both visually and in terms of smells.

Due to the powerful suction of the jet of air pulling the wastewater out of the toilet, the siphonic jet keeps the bowl sparkling clean. It will also typically have about twice as much water resting in the bowl. Although that means it uses more water than gravity fed toilets, it also means that the smells coming from the sewage pipes below will be blocked better, leaving the bathroom what a fresher air.
