Things You Need to Know Before Choosing a Pressure-assist Toilet

With so many configurations, options, and styles to choose from, a considerable number of homeowners are having a hard time choosing the right Toilet. Even with renowned industry leaders, you should only get the best Pressure-Assist toilet.

Basically, you will need to consider your budget, lifestyle, and preferences among other things to get the right toilet. Discussed below are some of the important considerations you need to make while shopping for pressure-assist toilet:

Toilet Configuration

The  leading toilet manufacturers offer an array of toilet configurations to suit different needs. In order to get the right design and appearance that complements your bathroom decors, you have to choose the right toilet configuration.

Here are some of the main toilet configurations you should consider:

Two-Piece Toilets

These are the toilet that has two main components: the toilet bowl and the tank. The two come as separate parts that need to be joined during installation. As compared to other toilet designs and configurations, two-piece toilets are more affordable.

However, they require a considerable amount of space to install. Again, two-piece toilets are comparatively hard to clean, especially the part in between the tank and the toilet bowl.

One-Piece Toilets

This is yet another toilet design, in which the bowl and the tank are fused together. Although costlier than the two-piece toilets, pressure-assist one-piece toilets are the right choice for that sleek, modern appeal you want for your bathroom. These toilets occupy less space in your bathroom and are comparatively easier to clean.

Wall-Hung Toilets

This is yet another space-saving toilet design you can choose for your bathroom. Pressure assist wall-hung toilets are meant to be erected on the bathroom wall, saving you a considerable amount of space on the floor. They are designed to give your bathroom a contemporary appearance and make the bathroom appear bigger.

With this toilet configuration, the cistern is usually hidden behind the wall. As such no pipework or ducts will be visible to the user. For a secure installation, you will need a wall frame to secure the toilet on the wall as the piece is rather heavy.

Water Efficiency

Water efficiency is something almost all homeowners would like to achieve in their homes. Not only is this friendly to the environment, but it can also save you some money in your monthly water bills.

Owing to improvements in the industry, toilets are now more efficient on water, with standard models dispensing only 1.6 gallons per flush (GPF).

Advances in hydraulic designs of the toilets allow them to save about 50 percent of water while performing just as efficiently as traditional 3.5 GPF toilets. The more efficient toilet models dispense about 1.28 GPF, saving 20 percent more water than standard models.

Then there are the ultra-high efficiency toilets that have a flush rate of 1.0 gallons per flush, without sacrificing on flushing performance.

Dual-Flush Options

Pressure-assist Dual-Flush toilets are renowned world over for their enhanced water efficiency. They allow you to use either partial or full flush to flush away your waste. For instance, a good number of them dispense 1.6GPF on a full flush and 1.28 for partial flushes.

In such a case, the partial flush will be used to flush liquid waste, while the full flush will come in handy for pushing away the solid wastes.

Bowl Shape

Regardless of the toilet configuration, pressure-assist  toilets are available in several bowl shape options.

For all the toilet configurations discussed above, the leading brands offer round and elongated bowl options. The right bowl shape will mainly depend on the size of your bathroom and your preferences.

Here are the two main toilet bowl shapes you should consider:

Elongated Toilets

These have a bowl that is elongated on the front to assume an oval shape. As such, elongated bowl toilets offer extra room for added comfort. You can also get the compact elongated toilets that are designed to fit into he same space as conventional round-front toilets would.

Round-Front Toilets

These feature a more compact design and are suited for installation in smaller bathrooms. In order to save on space, Round-Front toilets have a bowl that is almost circular in shape. As such, they are also suited for installation in powder rooms.

Size Requirements

Different toilets are suited for different applications. This is why you need to ensure that your preferred model is ideal for your bathroom size.

One of the important size considerations you need to make is the rough-in distance.

This is the distance between the bolts and the wall behind the toilet. Most toilet models are designed to bolt to the floor some 12 inches from the back wall. You can also get 10-inch or 14-inch rough-in toilet options with this manufacturer.

For a smaller bathroom, the 10-inch rough-in toilets will come in handy. The 14-inch rough-i toilets, on the other hand, are best suited for the larger bathrooms.

Flush Mechanism

Most traditional toilets use a Gravity-Feed mechanism to push waste from the bowl down the drain. In this case, the toilet uses the weight of the water to generate enough flushing power. Owing to their simplicity, toilets that use this mechanism are cheaper to buy and maintain.

In an effort to save more water, the leading toilet brands offer pressure-assisted flush toilets as well. These use air to boost the flushing energy of the water flowing into the bowl. Pressure-assisted toilets are known to deliver a powerful, and efficient flush every time you use them.

Our Final Verdict

As compared to Gravity-Feed toilets, pressure-assist toilets have more benefits to offer. The leading pressure-assist toilet models are efficient on water and deliver powerful flush performance. Such toilets are known to clog less often, and are easier to use.

The five toilet models reviewed above are some of the best in the industry, with regards to power, reliability, and efficiency of the Pressure-Assist flush mechanism.

Combining such a mechanism with innovative technologies like the EverClean surface solution by American Standard produces a truly superior product.

With this guide, choosing the best pressure-assist toilet model for commercial or residential application should be easy.
