If you’re planning a bathroom renovation or considering installing a toilet in an unconventional location like a loft conversion, basement or garden office you’ve probably come across Saniflo toilets. These clever systems offer flexibility where traditional plumbing might not reach, but they also come with plenty of questions, especially: where does the waste go from a Saniflo toilet?
In this blog, we’ll break down exactly how Saniflo systems work, where the waste ends up, common problems with Saniflo toilets, and how to ensure your bathroom macerator pump runs smoothly. So, let’s dive into the world of macerator toilet pumps and find out where the waste really goes!
What Is a Saniflo Toilet?
A Saniflo toilet is a type of macerator toilet pump system that’s designed to move waste from your toilet to the main sewer line, even if gravity drainage isn’t available. It’s ideal for areas where conventional plumbing is difficult or impossible to install.
Rather than relying on traditional gravity-fed sewage systems, Saniflo uses a bathroom macerator pump to grind and pump waste and wastewater through small-diameter pipes to reach the nearest soil stack or main drain.
Where Does the Waste Go From a Saniflo Toilet?
Let’s get straight to the point: where does the waste go from a Saniflo toilet?
The waste from a Saniflo toilet doesn’t disappear into thin air it’s cleverly pumped away through a small bore pipe (typically 22mm to 32mm in diameter) and directed towards your existing soil stack, drain, or sewage system.
Here’s a simplified process:
Flushing – When you flush the toilet, the waste enters a small tank behind or underneath the toilet.
Maceration – Inside this tank, rotating blades (like a blender!) macerate the waste into a fine slurry.
Pumping – Once macerated, a powerful pump pushes the slurry through narrow pipes up to 100 metres horizontally or 5 metres vertically.
Disposal – The waste is finally expelled into the main sewage system or septic tank, just like a standard toilet.
This process makes it possible to install toilets in locations far from your main soil pipe like under stairs, in basements, or in garages.
How Does a Saniflo Toilet Work?
Understanding how a Saniflo toilet works can help you troubleshoot problems and use the system more efficiently.
Sensor-Activated Macerator: Once you flush, a sensor detects the presence of waste and activates the bathroom macerator pump.
Blade Grinding: High-speed blades chop up the solid waste and toilet paper into a liquid.
High-Pressure Pumping: The system then pumps this liquid through small pipes to your main drain.
Automatic Shut-Off: Once the tank is empty, the unit shuts off until the next flush.
This means that even if your toilet is far from a vertical soil stack or below the main drainage line, a Saniflo system can still transport waste efficiently.
Common Problems With Saniflo Toilets
While Saniflo systems are incredibly useful, they’re not without their issues. Here are some problems with Saniflo toilets you should watch out for:
One of the most common issues is blockage. This usually happens when non-flushable items like wipes, sanitary products, or even too much toilet paper are flushed down. The macerator can’t break these down, leading to jams.
If your Saniflo is making grinding, buzzing, or vibrating noises even when not in use, it could indicate a faulty switch, blockage, or worn macerator blades.
Odours from your Saniflo toilet usually mean trapped waste or poor ventilation. In some cases, the system may need to be descaled or professionally cleaned.
Water or waste leaks are serious and can damage your floors or walls. These leaks often stem from cracked pipes or loose connections and should be addressed immediately.
Since Saniflo relies on electricity, any power outage can disable the system. This could result in backed-up waste if the unit is used during the outage.
Maintaining Your Bathroom Macerator Pump
To keep your bathroom macerator pump in good condition:
Only flush toilet paper and human waste.
Avoid using harsh chemicals; instead, use Saniflo-approved descalers.
Clean the unit regularly (every 3–6 months).
Schedule professional servicing annually, especially in high-use environments.
Preventative care not only saves money but also extends the lifespan of your macerator toilet pump.
