Although a pressure-assist toilet looks a lot like a traditional type, inside the tank, it is a lot different. It is fitted with an air-filled pressure container so that when it is flushed, compressed air pushes the water into the toilet bowl. The force of the water makes for a much more powerful flush and requires a lot less water. Another benefit of this is that because water is pushed through the system at a greater force, there are far fewer blockages than you would experience with a standard gravity toilet.
Pressure assist toilets are now commonly used in new houses but there are many benefits to using them in older homes as well. For example, the tank's design means that it does not experience condensation issues which is often a problem in humid conditions. Also, because the pipework in older homes makes it prone to clogs and blockages, a power assist toilet can push waste through the system quickly and help to remove any trapped waste.
Of course, there are some downsides to pressure-assist toilets that you should take into consideration. To operate successfully, they generally require around 20 to 30 PSI which could be a problem in homes with low water pressure. Also, while pressure-assist toilets need little maintenance, they do cost more initially. Another problem for some is the noise of the flush as it is a lot louder than a standard toilet so have these things in mind when deciding what is right for your home.
