Pressure Assist Toilet: What it is, Problems, Pros & the Best Review

Besides the normal gravity-fed toilets, most homeowners have now appreciated the need to install pressure-assisted toilets. Pressure-assist toilets usually have a tank inside of another tank such that when pressure is created in-between the tanks, the aftermath is a powerful flush that leaves your toilet cleaner than before.

These toilets have proved to be very effective in the recent past and this is the reason they are a common feature in most homes. Inhere, find out what exactly a pressure-assisted toilet is, how it works, pros and cons, some of the best models, and finally the frequently asked questions about these bathroom units.

What is a Pressure-assist Toilet?

This is a toilet that has an additional tank inside the main tank. As a result, a large amount of air pressure is normally created between these two tanks. When this toilet is flushed, the compressed air in the air chamber is usually released. With the pressure joining the force of gravity, the downward flush is typically explosive and can thereby make your toilet bowl cleaner than ever.

For this reason, you are likely to find this toilet in commercial settings such as in restaurants, hotels, and so forth. However, these toilets have started becoming very common in residential bathrooms.

How does a Pressure-assist Toilet Work?

Once you open this toilet, you will see a black air bladder instead of the conventional pump that you would expect to find in a normal toilet. As its name indicates, this air bladder usually contains air. However, it also fills with water, and when this happens, the air insides get compressed.

Once you flush the toilet, the pressure created will expel the water with massive force. The aftermath of this is a greater flushing power, as mentioned earlier. In the end, a fill valve such as the one found in a standard gravity-flush toilet opens. This allows water to refill the pressure tank, and the cycle gets repeated. The good news is that this toilet usually has a pretty simple mechanism compared to other toilets.

Pressure-assisted Toilet Problems/Cons

Pressure Assist Toilet Retrofit

Can you convert a regular toilet to a pressure-assist? It is not possible to mold the pressure-assist technology with the current gravity toilet.

To start with, the two technologies use different designs. In the gravity-fed model, the passageways from the tank to the bowl and the bowl’s rim holes are designed to transport water from the tank.

For the pressure-assist model, the bowl is designed to accept water that is forced down with great pressure. Apart from the design of the bowls, the tanks of these toilets are designed for different components. As a result, they are not interchangeable.

Are Pressure-assist Toilets Dangerous?

Pressure assist toilets are not always safe. They have a history of exploding. However, when properly installed and used in the right way, they pose no danger.

Since the tanks of these toilets contain a lot of pressure after flushing, there have been reports of exploding. Some consider these units ticking time bombs. The explosion may not only injure you but can also cause property damages.

At the same time, they cannot provide an effective flush if your water supply system is weak. If the water is not enough, your toilet won’t flush properly leading to clogs and messes that won’t be easy to clean.
