Best Pressure Assisted Toilets

More often than not, renters and first-time homeowners will stick it out with whatever toilet is already available. A thorough cleaning and maybe a toilet seat replacement are all bathroom newbies usually need. But if you’re looking to replace your toilet or make it more eco-friendly, a power flush toilet or pressure flush toilet may be the way to go.

While looking for the best pressure assist toilet, pay attention to the drain line and cleaning details. Ideally, the high-pressure toilet you choose should push waste out of the bowl and into the drain line faster and more efficiently than a traditional gravity flush.

You’ll also save yourself some money from replacing flappers, chains and other mechanisms because they’re unnecessary for these types of toilets. And best of all, these cost-effective options can be installed the same way as gravity toilets and require the same water pressure. Check out these 15 options for potential buying ideas.

Why choosing a lower-flush volume toilet matters

People don’t often think much about their toilets until the one that’s included starts to clog, won’t flush at all or parts keep breaking. The saying “If it ain’t broke, don’t fix it” is a common saying for a reason.

While this post is not meant to tell you to yank out your perfectly working toilet, there are benefits to consider what works for you for the long run. Some guests may not even notice that there’s a difference between a pressure assist toilet versus a traditional tank-type toilet. Give or take a few, most flush the same. The performance of a pressure assist toilet may sound the alarms though.

Unlike some older, lesser-quality version that sound like someone gargling instead of flushing a toilet, pressure assist toilets should normally be high quality.

The pressure of these toilets should flush waste out of the bowl and down the drain faster and more efficiently than a gravity flush toilet. This is mainly due to the higher velocity and pressure of the rim jets. In addition to wasting less water, you will find yourself saving money in other ways. Skip replacements or initial needs for toilet mechanisms such as flappers or chains. Instead, pressure assist toilets use flush activation for easy maintenance.

How to clean a pressure assist toilet

With its high-pressure flushing options, these kinds of toilets can reduce stain and odor-causing bacteria, mildew and mold on the surface. Generally speaking, toilets should be cleaned at least once a week. This includes toilets that “look” clean. While these kinds of products help to reduce waste from staining the insides of the toilet, even the best kind of toilet can still have buildup.

Just as kitchen and bathroom sinks that “look” clean should be wiped out daily to avoid E.Coli and Salmonella, so can toilets if all fecal matter is not properly removed. Additionally, make sure to wipe out the outside of the toilet too. Sometimes people will swirl the toilet brush around the inside but not dedicate enough time to the other areas.

Spray the handle, around the rims and all over the floor bolt areas, too. These areas often get ignored but then start to yellow or show signs of debris with time. If you make cleaning the entire toilet a priority each time, you may find yourself with a cleaner toilet both inside and outside. Read our reviews of the best toilet cleaners available here.

How to install a pressure assist toilet

If you’ve installed a gravity toilet, then you already understand the general process of installing a pressure assist toilet. The water pressure is usually the basic water pressure for a traditional toilet’s pounds per square inch (psi).

Read the instructions carefully to know exactly which tools and supplies are needed in order to install each one. They are not all created equally. Of course you can always pay for installation, but if you want to save a few bucks and have a bit of DIY crafty behavior in you anyway, this installation job may be about like lifting and loading any other item.

These toilets can be used in pretty much anywhere—assisted-living facilities, bars, churches, gas stations, government buildings, hotel rooms, medical offices, nightclubs, offices, residential apartments, restaurants, schools, strip mall retailers.

Bottom Line

From the 15 options above, hopefully one of these make sense for your bathroom or powder room needs. For homeowners (or realtors) who may have seniors, people with disabilities or others who have special needs, pay special attention to the toilet options that are American Disabilities Act (ADA) certified.

Ideally, all of the options have one-flush results, and judging from most of the reviews, they do. But whether you’re looking for an elongated seat or a round seat, there’s a little bit of everything for both. But before committing to such a permanent purchase, take into consideration your own height and build to make sure that the measurements of the seat are comfortable for you and the rest of the residents’ needs.

While there are many reasons why major appliances may or may not work in the long run, double-checking the measurements is the easy part. And having an eco-friendly toilet like one of these pressure assist options is even better for your long-term needs.
