Gravity fed toilets are the basic home toilet design that most people are used to. The toilet does not require any type of power to operate; the flush mechanism is powered by gravity. When flushed, the valve opens and gravity pulls water into the bowl, causing it to flush its contents. This is how the original toilet was designed and has not changed much in centuries. People love gravity fed toilets because they are simple, affordable, and easy to use. Plus, they are simple enough to fix on your own, reducing the long-term costs. In reviewing gravity fed toilets, we considered ease-of-use, cost-efficiency, installation requirements, and more.

How Do Gravity Fed Toilets Work?

Gravity toilets work by dropping a large amount of water into the bowl at a relatively high speed, which moves the water in the drain. This, in turn, opens a valve under the bowl and causes the water in the bowl to drop out into the drain. Gravity fed toilets are often fed by a valve in the tank or flushing system that is opened by the handle. This valve lets in a large amount of water, which is pulled down by gravity into the rest of the toilet.

What is the Difference Between Gravity Fed and Pressure Assist Toilets?

The difference between gravity fed and pressure assist toilets is that gravity fed toilets only rely on gravity to flush. All of the pressure comes from gravity rather than a pressurizing system. Gravity toilets work well in most situations, but their ability to pull things into the drain depends on the amount of water used and several other factors. Pressure assist toilets can handle more things in the bowl since the added pressure creates a stronger vacuum when flushed.

Pros and Cons of Gravity Fed Toilets

One of the best aspects of gravity fed toilets is that they do not require any additional mechanical or electrical systems to work. Therefore, they always work as long as they have enough water. The downside to a gravity fed toilet is that it requires a large amount of water for a thorough flush, which can increase your water bill.
