What is a Saniflo Macerator?

First things first, what is Saniflo? It’s a brand that’s become synonymous with upflush toilet systems, which can be a lifesaver in small spaces. Instead of relying on gravity to move waste down the drain, these use a pump to macerate and pump it up to your existing plumbing system.  Saniflo appliance is also known as a macerator. This particular appliance differs from a traditional toilet in two ways. First, the high-speed rotating blades break down human waste and paper.


Second, it can be positioned some distance from the main soil pipe (there are limits, however). The system uses a centrifugal pump to remove waste from the toilet and pump it into the soil stack. It can be connected to your WC anywhere in your property (within reason) positioned behind the toilet pan.


Choosing the Best Saniflo Macerator

Now, here’s where it gets interesting. There are different types of Saniflo macerators with different characteristics. The pump sizes vary depending on your specific requirements. If it’s just for a toilet, a smaller unit will probably be sufficient. However, if the installation site is a distance from the soil stack, then a unit with a bigger, more powerful pump would be needed. It’s all about finding the right tool for the job, see our product page for more information.


How Does a Saniflo Macerator Work?

A Saniflo toilet consists of four main components:

  1. Impeller: This is like the engine of the operation. It helps create the pressure needed to move waste.
  2. Micro Switch: It’s like the brain that tells the system when to start and stop.
  3. Blade (Macerator): These blades shred waste into tiny pieces.
  4. Float Switch (Membrane): This one keeps an eye on the water level to make sure everything is working as it should.

Each of these parts plays a crucial role in ensuring the efficient removal of waste from the WC.


Tips for Installing a Saniflo System

Now, before you rush into a Saniflo installation, here are some tips and hints to keep in mind:

  • Check the Ideal Distance: The system has a powerful pump that sends waste into the main sewer. Always consult the manufacturer to determine the ideal distance from the soil stack, as online information can sometimes be contradictory.
  • Electrical Work: If you’re dealing with electrical installations in your bathroom, they come under Building Regulations. So, it’s crucial to engage a certified electrician to complete the electrical work or a plumber who is qualified.
  • Prevent Freezing: Don’t let your pipes freeze. Make sure to use adequate lagging to protect them from the cold.
  • Straighten the Discharge Tube: Keep your discharge tube as straight as possible and limit bends and elbows in your discharge pipe to help the pump work efficiently. Ideally, any elbows should be less than 45 degrees, and the pipe should be as straight as possible. Too many elbows or undulations can lead to blockages.
  • Follow Manufacturer Recommendations: Support all pipework according to the manufacturer’s recommendations. They know their products best and can provide the right guidance.

Remember, a Saniflo install can be a game-changer for small bathrooms, but it’s essential to do it right. When in doubt, don’t hesitate to call in the experts.
