What is a Gravity Flush Toilet?

If you want to find out the differences, you first have to know the definitions. According to their names, the gravity flush toilet flushing functions are related to gravity. First, push the handle to open the valve. Use the handle to open the valve within the tank; the water will fall by the work of gravity.

Difference Between the Pressure-Assisted Toilet and Gravity Toilet

The world is full of diversity. The choices of a variety of people are not the same. So they collect the different things as their necessity. There are some differences between the pressure-assisted system and the gravity toilet system.

Difference in Price

The gravity toilet is comparatively lower in price. The gravity-assisted toilet’s build and design are similar to other pricier toilet systems. It also includes ceramic materials. But why is the price lower than others? The operational process of the toilet system gets less equipment than other toilets to reach the tank. 

On the other hand, the pressure-assisted toilet is pricier because of its highly functional system. It is not from gold, but its extensive price is for the complex pressure cavity cylinder. But pressure-assisted toilets also include ceramic-like gravity toilets. You may replace the sewerage delivery pipes of the toilet tank. If you think water pressure increases after a few months, you can exchange them for better service. 

We can conclude that the functional difference between the two kinds of toilets differentiates the prices.  

Gravity Toilet is Easy to Maintain

Gravity toilets have been famous for many years among all classes of people. So a large number of people are familiar with the toilet system. The maintenance cost of a gravity toilet is less expensive than the pressure-assisted toilet. How a Standard Gravity Flush Toilet Works
