Upflush toilets are not new technology, but they’re gaining traction in the US. European countries like France and Italy have been using them for years to solve tight spots and make it easier to install bathrooms below preexisting lateral lines (especially since there is no need for an extra room that would take up valuable space).

The first version of this type was developed by Saniflo back when Western Europe had very different plumbing than we do now; these types were designed specifically with older homes where installing a conventional toilet wasn’t feasible because it would cause intersecting laterals or even flooding on your own property line!

Toilets are a crucial component of every home. They come in a variety of sizes, designs, and settings. When it comes time to design your dream home, renovate your space or even make some temporary changes to adapt to life situations, you will undoubtedly find yourself dealing with the toilet issue. Which ones should you buy?

Can it be installed where you want? Can you afford it? Will it look good? These are all good questions. When you consider conventionally installing a new toilet, you will stare into a barrel of excessively expensive and lengthy installation processes.

In recent years, the market has demanded state-of-the-upflush toilet systems. When adding new accessories to an existing home, these toilet systems are designed to eliminate the need for a large underground water pipe.

When it comes to finding a new toilet for your area, the upflush toilet system is a perfect alternative to a traditional toilet. Are you in a bind because your plumbing system lacks a downward drainage device? If that’s the case, an upflush toilet is your best option.

What is an Upflush Toilet?

Upflush Toilets

To move the size of your toilet and link it to the main sewer line, the Upflush toilet system uses a macerator and pumps. It is based on the idea that instead of using gravity plumbing at ground level, you can chop the size into a fine consistency and pump it through overhead PVC pipes to a point in your home more suitable for connection to the main sewer line. This alleviates the need to break down your floors and saves you a lot of money both at the contractor and plumbing need.

Crushing phase

When the waist is pushed down and behind the toilet where the crusher and hose are housed in a white box, it enters the crusher first. This shredding machine comprises well-designed blades that operate at high speed, grinding up all the crud into a finer, more readily movable consistency.

The Pump out Phase

After the macerator has done its job, the belt is pressed into the pump tank consisting of the diaphragm. When the waistline is filled to this diaphragm, the pump is activated and projects the entire waste into a 1-inch-thick tube through a one-way non-return valve. This hose travels no matter the length you need from your toilet to the main sewer pipe, delivering the size to the main system.

Ready for Business Phase

After the waist is pressed and the pump is turned off, the one-way valve closes, preventing the penetration of gray matter. The macerator, as well as the pump, is now empty. Therefore the toilet is ready to go through the process again. The waist is not adjusted for a long time, and there is no need to worry about the accumulation of unpleasant odors or wear of the system due to excessively long holes in the waist. When the toilet bowl returns to its standard cleaning state, the gray matter is long gone. 

Installation of Upflush Toilets for Basements

A 3/4- or 1-inch PVC drain pipe, a 1 1/2-inch PVC drain pipe, and a 2-inch PVC pipe for drain connections are commonly included with a toilet upflush kit; also, you will need to provide a 3/4- or 1-inch PVC drain pipe, depending on the type. All of these hoses connect to the macerator, not the vessel.

The drain hose connects to a reduction connector that you attach to the outlet at the top of the cutter. You can extend it to 15 to 25 feet in height (depending on the model) and a horizontal distance of up to 150 feet to connect to the sewer.

A ventilation pipe is attached to another hole at the top of the cutter and goes up into the wall to connect the building’s ventilation network.

After attaching the 2-inch waste hoses from the appliance drain to the macerator inlets, connect the bowl by tightening the flexible connector that came with the kit. The water supply hose, of the same type as a conventional toilet, is screwed onto the toilet tank and the water supply shut-off valve. Then attach the toilet bowl to the floor with the included lag screws, plug in the macerator, and you’re done.

Reasons for using an Upflush toilet

Reasons for using an Upflush toilet

Freedom of choice

The first and most crucial thing to realize about an Upflush toilet is that it can be attached to practically any surface. You might have unused space in the basement or beneath the stairs, you’d like to convert into a bathroom. This could be impossible or extremely expensive if you install a conventional system such as a Monoblock toilet. The upflush system shows its colors with its ability to set up almost anywhere! This gives you complete freedom of choice.

No need to tear the floor

Water supply systems rely on power sources, water sources, and PVC. Using these pipes means you don’t have to tear floors to install plumbing. Extend the pipes as needed until you can connect them to the main water lines

Easy to install

These systems are much lighter and faster to install than a conventional toilet. It is within reach of even a novice. An expert should install this system themselves by simply following the supplied installation guide.

Decent warranty

The system and pump come with a warranty covering you for years. So you don’t have to worry about expensive repairs.

It’s easier on a budget

Upflush toilets have a similar price as regular toilets when it comes to actual toilets. But when you consider the potential plumbing, digging, and redesign involved in the installation. From a conventional system, it quickly becomes apparent that up flushing systems are much cheaper. 

You can add a sink, shower, and bathtub

If you desire to create a complete bathroom, the upflushing system adapts to it. Connect the sink, shower, or bathtub sockets to the system via the supplied seals, and you are ready; no underground plumbing is required!

Frequently Asked Questions

How does the Upflush toilet work?

The powerful macerator has a rotating blade that shreds and crushes solid materials such as human waste and toilet paper. When mixed with rinsing water, the solid material turns into fine slurry that travels easily through a narrow tube to the top. The silent electric pump moves the fine slurry upwards under pressure.

Do you need to ventilate the Upflush toilet?

All plumbing fixtures must be vented. Like all plumbing fixtures, an upflush toilet should be vented into the main chimney of your home. It extends from the main sewer pipe to the roof. The tank comes with a ventilation port on top.

How much does an Upflush toilet cost?

Upflush toilets typically cost between $600 and $800. For a total cost of $700 to $1,000, a competent plumber can usually install one in an hour or two ($ 100 to $200). Wastewater disposal systems cost from $ 400 to $ 700, depending on the size of the tank. However, these systems do not come with a toilet, so you must buy them for an additional fee.

How do I clean my Upflush toilet?

To clean the toilet bowl with an extra rinse:

  • Pour 1 to 2.5 liters of non-acidic toilet cleaner and descaler into the toilet bowl.
  • Allow the descaler to enter the macerator by turning on the macerator pump for a few seconds.
  • Restart the macerator and let the descaler work for another 2 hours.

How far can the Upflush toilet pump go?

The unit pumps wastewater upwards up to 15 feet and 150 feet horizontally (with gravity drop). After the water level in the tank drops, the microswitch turns off the unit until the flush is reactivated. 


If you’re planning to renovate permanently and the main plumbing is there, you may not need an upflushing system. However, suppose the location where you plan to build a toilet is remote from the mainline. In that case, you are doing so temporarily, you want to save money on installation. Or you want the satisfaction of doing it yourself, an upflush toilet system is the only option.
