This post is part of a series about bathroom remodeling as well as part of a sub-series on toilets (yes, toilets!). To access either of the lead posts please select one of the links below.
In the beginning all toilets were gravity flush toilets. What this means is the flushing mechanism works by opening the flush valve then allowing gravity to move the water from the tank into the bowl.
The actual flush is accomplished by the water suddenly being dumped into the bowl. If you ever want to see this for yourself, get a 5 gallon bucket at home depot and pour water directly from the bucket into the toilet bowl.
However gravity flush toilets use a lot of water. We’ve created low flow gravity flush toilets that use less water, but some of them flush very poorly. For that reason, assisted flush toilets were invented.
The mechanism where by this tank refills also creates the storage of compressed air in the mechanism (see the diagram below).
When this toilet is flushed, a blast of compressed air accompanies the water and the bowl is cleared and cleaned with much less water used than is needed with a gravity flush toilet.
Pros and Cons
The pros and cons are pretty simple….. Gravity flush toilets use much more water, but assisted flush toilets are much more expensive, not only to buy, but also to later repair.
The replacement guts of some assisted flush toilets cost more money than some gravity flush toilets in total.
If using less water is important to you, assisted flush is the way to go. However, with current technology it will takes years to save enough on water to cover the cost difference between the two.
