There are two types of pressure assist toilets – front load and top load. Both designs have their pros and cons. Let's take a detailed look at each of them below.
Front-load models work by storing additional water in a separate tank above the bowl which allows it to push down on waste matter inside more forcefully than conventional toilets do.
Top load models work by storing the additional water in a tank located at the bottom of the bowl.
They use about 6 liters more water per flush, but require less force to push down on waste and can cause clogs because they are forced into a confined space that is already filled with solid matter and released upward through a small opening above that point.

If you live in an area that has hard water or very high mineral levels in your drinking water, consider investing in either type of pressure assist toilet since this could be contributing to your toilet's inability to fully flush away waste material from your plumbing system.
