Traditional toilets use the power of gravity to dispose of the flushed water into the sewer system. But many times, people want to install a toilet in a basement or in a tight place where the drainage line is above the room and gravity can’t help. 

In these kinds of situations, Upflush toilets come to the rescue. The flushed water from an Upflush toilet will go to the rear of the toilet and up into a macerator or garbage disposal. It will then go to an external pipe for final disposal.

Though Upflush toilets are getting popular in recent years, they were created in the 1950s by Saniflo. In this article, we will learn what an Upflush toilet is along with its pros and cons. We’ll also try to focus on answering the question – “How does an Upflush toilet work?”

Using upflush toilets is quite similar to regular toilets. The sole difference between them is in their waste disposal methods. Traditional bathrooms employed flushing to remove the waste and allow gravity to flow it down into the pipeline. 

The flushed water from an Upflush toilet will go to the rear of the toilet and up into a macerator or garbage disposal. From there, it will go to an outward pipe. It is also known as a macerating toilet due to the usage of the macerator.

Upflush bathroom system has become popular due to the less hassle during installation. The installation cost of an Upflush toilet system on a small or old bathroom is pretty low. Also, Upflush toilet installation is more manageable than putting up a traditional toilet.

Are Upflush Toilets Reliable?

Toilet technology has come a long way since the invention of the flush toilet in 1775. It was not until 1884 that John Harrington designed and patented the first “up-flush” toilet. Which is still used today.

Many people are worried about the reliability of up flush toilets?. But don’t worry, because the up-flush toilet is reliable for many reasons. Some of the reliability reasons are given below.

  • it’s easy to install.
  • it’s inexpensive.
  • there are no moving parts or complicated mechanisms inside.
  • it can usually go 20 years before needing repair.

An upflush toilet works following almost the same principle as that of a typical s-trapped toilet setup in case of operation. The upflush toilet design allows water to be directed into the bowl via an angled pipe, instead of through a vertical one as with conventional toilets.

This means that no matter how much water you use to clean your bottom, you won’t have any leaks at all!

So you can reasonably rely on upflush toilet systems the same way you would trust a typical toilet set up to function.

Using gravity, traditional toilets flush down the slope to your pipes. The waste from an Upflush toilet system flows out the back of the bathroom and into a pump with a macerator. 

The macerator contains a rapid-cutting blade, which is turned on automatically and transforms the waste into a fine slurry. This is why Upflush toilets were first called grinder toilets when invented in Europe in the 1950s. The trash is crushed up and pumped to your septic tank through your house’s internal plumbing. 

You don’t even have to worry about the maintenance of the toilet. The pump and the macerator last more than a decade before it needs a checkup. So, in most cases, you need to install the toilet and the pump, and you can forget about the maintenance of the macerating unit.


There’s a lot of buzz and misinformation about upflush toilets, so we should clear it all up for you. Yes: they work just like any other toilet!

The only difference is that after your butt goes to town on them (burp!). The waste will be disposed of off into a pump where the macerator gets rid of those pesky bits in one easy swoop by flushing them down its drain pipe.

This means no more odors or clogs from solidified soap scum anymore either because there isn’t anything left behind but water vapor at this point anyway thanks to how powerful these things operate.

By using a pump, you can flush your toilet without any of the hassle associated with other systems.

Upflush toilets are simple and streamlined because they only require one small unit that sits behind or connects to an extension pipe for installation into power outlets–no more worrying about installing valves!

The waste from these types of fixtures goes right up through regular pipes but won’t end up back inside where it started like in some cases when people use their septic tanks instead (or if there isn’t enough room within its boundaries).

A visual difference between standard restrooms and those equipped on being “upflushed” is how often air needs replacing: While most maintain atmospheric pressure constantly thanks to natural ventilation.

Worried about maintenance? Don’t be – The pump is maintenance-free! No more worrying about getting your waterlogged, dry lawn back.

After 10+ years of use, you can simply replace the motor and it will be as good new – all for less than $200 USD in parts prices alone (it’s not even something that needs replacement).

Upflush Toilets VS Urinals

A flush toilet is a device that flushes water and air into a toilet bowl to dissolve human waste, force it through the drainpipe, and into an available sewage system. This machine also uses some mechanical power to raise the water level in the bowl before flushing. Many people confuse upflush toilets with urinals. While they are similar in many ways, there are some key differences that actually make them unique!

Upflush toilets use pressure from the incoming water supply to flush the waste down the drain while urinals rely on gravity alone to pull waste away from the user.

Although both upflush toilets and urinals are types of flush toilets, but they are not the same.

Differences Between Upflush Toilets and Urinals:

Let’s take a look at some key differences between upflush toilets and urinals:

  1. Urinals were invented much earlier than most people think. The first urinal was patented in 1885, while the first upflush toilet was patented in 1964.
  2. Upflushing toilets use water pressure to move waste down the drain when flushed, while Urinals use gravity to move waste out of the user’s body after cleaning.
  3. From upflush toilets, Urinals are considered to be more sanitary. Urinals have a trap door at the base of the urinal that prevents odors from entering the bathroom.
  4. Urinals are smaller in size than most upflush toilet systems. The bowl of a urinal is usually only half as big as a regular toilet bowl and can be moved to different locations with ease since they are small and light.
  5. Most urinals come with extensions that can be added on so more people can use them at one time (making them more sanitary than using regular toilets). Upflush toilets, on the other hand, cannot be used by more than one person at a time.
  6. Urinals are a lot more affordable than the upflush toilet systems and are used in commercial settings. Since upflush toilets use more water, they might not be as eco-friendly as you think they are.
  7. Most urinals have smooth surfaces and don’t have traps, while upflush toilets commonly have traps that contain odors.
  8. While urinals have a smooth surface and don’t have traps, upflush toilets are more germ resistant and have smoother surfaces for easier cleaning and fewer bacteria growth.
  9. Most people consider urinals as a bathroom accessory and consider them to be separate from the toilet area, while in reality, upflush toilet systems are part of the overall bathroom design.
  10. Upflush toilets use flushing water pressure to flush waste away instead of using gravity or mechanical power to pull waste away with the help of a trap door.

How Much Is the Cost of An Upflush Toilet?

Upflush toilets are very cheap relative to the traditional toilet installation cost. Installing traditional toilets includes drilling holes, breaking floors, maintaining close distance with the main sewer lines. But an Upflush toilet can save you from breaking your bank as well as your bathroom. 

As it does not need a downward pull for the waste to go to the sewer line, you can even set it up under the sewer line. Then you can connect the discharge pipe to the main sewer line. 

All things considered, an Upflush toilet will cost you around $1000. With the installation and all, you can get it done within $2000 or less. You can avoid spending $10,000-$14,000 on a bathroom install if you go for the Upflush toilet system.

So, if you want to save money and make your plumbing lines mess-free, you should definitely consider installing one of the best upflush toilet systems.

But if you find it difficult to choose, our careful evaluation might help you to pick. Read our guide on best upflush toilet systems reviews.

How to Choose the Best Upflush Toilet?

When you are looking for an Upflush toilet for your bathroom, there are some pointers you can take from this article. 

First, you have to decide if you want full bathroom coverage with the Upflush toilet and shower. Then the pump and macerator sit as the centerpiece of the bathroom. You can attach shower lines and sinks to the Upflush toilet. The “SaniPlus” or “SaniBest Pro” Upflush toilet will make for such a full bathroom coverage.

Other Setups

If you want a partial or half-bathroom setup for an Upflush toilet, you should look for “SaniCompact” for the toilet and the sink. It is a self-contained unit that hides the pump inside and gives one connection for a sink.

For greywater solutions, like kitchen or shower water only, you can consider the “SaniSHOWER” or the “SaniVITE” models. It’s appropriate for dishwashers, laundry machines or showers, or baths.

Upflush toilets are helpful if the bathroom is well below the sewer line (more than 12 feet or so). Otherwise, the distance is too much. Before installing an Upflush toilet, you should measure the distance of the bathroom from the sewer line.

The commode connects to the macerating unit with a pipe connection. Some manufacturers combine the toilet units and hide the macerating unit within the commode. This makes the setup more compact and portable.

How to Install An Upflush Toilet?

Installation of an Upflush toilet takes a moderate level of skills that you can master with some learning time. You can always call a plumber to install the toilet in your bathroom. But if you are a one-person army who likes to do it himself, here’s a brief guide about installing an Upflush toilet.

Brief Installation Guide

Step one: Check the depth of the place from the main sewer line. You are going to need a discharge pipe according to the distance from the sewer line.

Step two: Make a base for the macerator unit stable and reasonably level with the surface. You can build a 2×2-inch frame and pour concrete for ease, then set the unit on it.

Step three: Install an iron flange for support to prepare the unit for the toilet. Use bolts long enough so that you can mount the toilet.

Step four: Assemble the float switch that will trigger the pump. Install the discharge pipe and place the pump in the tank. Before sealing the unit, check if the pump works.

Step five: Connect the discharge to a drainpipe which leads to a bucket or drains. Tape the discharge pipe’s joints as the pump is very forceful. 

Test the pump by slowly pouring water into the tank. Once the water reaches the correct level, the float switch will trigger the pump and discharge it.

Step six: Install the 3-inch vent pipe. Install the lines from other plumbing tools if you want.

Step seven: Install a backflow device to the discharge pipe to ensure that the wastewater does not flow back into the tank. Connect a 2-inch discharge drainpipe to the discharge unit and connect it to the house’s sewer line.

Step eight: Install the supply pipe.

Step nine: Finally, install the toilet.

By following these steps, you can install an Upflush toilet within 5-6 hours. So, it may not be tough to install an Upflush toilet if you have at least some kind of knowledge about house tools and plumbing.
