What Is a Saniflo Toilet and How Does It Work?

If you’re planning to add a toilet in a new location such as a basement, loft conversion, garden room or a new en-suite, you may have come across the term Saniflo toilet or macerator toilet systems. But what’s the difference, and how do they work?

This guide explains everything homeowners need to know, from how these systems function to why ‘Saniflo’, the inventor of the macerator toilet, remains the most trusted and reliable brand on the market.

What Is a Saniflo Toilet?

A ‘Saniflo toilet’ is a term for a toilet which is attached to a Saniflo macerator. By using a Saniflo macerator, homeowners can install a toilet or full bathroom almost anywhere in a home, even where traditional gravity plumbing isn’t possible, practical or cost-effective.

Unlike standard toilets that rely solely on gravity and large soil pipes, a ‘Saniflo toilet’ uses the attached macerator pump to break down waste and pump it through small-diameter pipework to the nearest soil stack or drain.

This means you can install a toilet:

• In a basement below the main soil pipe.
• In a loft conversion.
• Under the stairs.
• In outbuildings or garages.
• Anywhere far from existing drainage.

Saniflo: The Inventor of the Macerator

Saniflo invented the macerator system in 1958, and continues to lead the market with reliable, high-quality products made in Europe. Saniflo is therefore a well established brand for macerators, though it’s important to remember that not every Saniflo is a macerator (we do more than just macerators), and that not every macerator on the market will be of Saniflo’s quality.

Saniflo Toilet with Built-In Macerator

‘Saniflo toilet’ is also often used to describe some of our products which come complete with the ceramic toilet and macerator system together, for example the Saniflush and Sanicompact. These products offer convenience when purchasing and installing the toilet, and the Sanicompact in particular is great for installations where space is limited, for example under the stairs, or in small en-suites.

How Do Saniflo Toilets Work?

So, exactly how do Saniflo toilets work? Understanding this is simple once you know the key components inside a macerator unit.

When you flush a Saniflo toilet:

1. Waste and water enters the macerator unit positioned behind the toilet.
2. A membrane detects rising water inside the unit and engages a microswitch.
3. The motor automatically activates.
4. Rotating macerator blades and water break down waste and toilet paper into fine slurry.
5. An impeller pumps the waste through narrow pipework (usually 22 to 32 mm).
6. The waste is discharged into the main soil stack or drain.
7. The system stops automatically once empty.

All of this happens in just a few seconds and the noise generated is normally no louder than flushing a standard toilet.

Key Components Explained

The essential parts found inside a macerator are:

• Membrane: Detects water level and pressure changes when the toilet is flushed.
• Microswitch: Triggers the motor when the unit fills up.
• Blade/Macerator: Cutting blades that liquefy waste.
• Impeller: Pumps the processed waste through pipework.
• Motor: Drives the blades and pump.

These components work together seamlessly to provide efficient removal of waste and water from the macerator unit.

How Do Macerator Toilets Work?

The essentials functions of macerators are similar to that of Saniflo macerators explained previously, but regardless of the brand, how do macerator toilets work in general compared with standard toilets, and why and when should you use one?

Standard toilet without a macerator:

• Require gravity-fed waste pipes.
• Must be located near the main soil stack.
• Can be costly to install in new areas.

Macerator toilets:

• Use electric pumps to move waste.
• Require only a small diameter discharge pipe.
• Can pump waste horizontally and vertically.
• Allows flexible installation anywhere in the home.
• Depending on the model, can also pump waste water from basins, showers, bidets etc.

A macerator can typically pump vertically up to around 5 metres or horizontally up to around 100 metres. This flexibility makes them ideal for renovations and extensions where conventional plumbing would be expensive or disruptive.
