How Do Saniflo Up Flush Toilets Work?

Adding a new toilet to any room in your home can seem like an impossible feat. Not only is it necessary to break floors and install complex plumbing, but you’ll also have to find a way to connect your new bathroom plumbing to your current main drainpipe, which may be too far away.

While you may think that adding a new bathroom to a tricky space will never happen, there’s an easy and affordable way to get around bathroom plumbing problems: Saniflo. Saniflo products are innovative, inexpensive, and guaranteed to make installing any toilet system a snap. Saniflo has been manufacturing upflush toilets for many years and is a subsidiary of French multinational company that was formed in the 1950’s

The Saniflo toilet system is unlike any other bathroom pumping system on the market. Instead of attempting to attach new plumbing to a main drainpipe that could be more than 100 feet away, Saniflo’s macerator does all of this work for you. How? Not only can Saniflo’s macerator send waste up to 150 feet away, but it can also send waste up towards any main drainpipe – up to 18 feet—thanks to Saniflo’s unique upflush toilet. No other water pumping system can do these things, which is why Saniflo is quickly becoming the most popular choice around the globe.

How does Saniflo work? The process is really simple. First, when waste is flushed a patented macerating device inside of the tank activates. Within a matter of four seconds, the waste inside of the tank is completely pulverized. Then, the waste is pumped into a septic or soil stack up to 150 feet away. When the process has been completed, the macerating device inside of the tank is deactivated. As soon as the toilet is refilled with water, the tank is clean and empty.


The best part about Saniflo is that you don’t need major construction in order to install this unit – in fact, you can install it on your own in most cases. Since waste is flushed through a pipe that measures a mere one inch in diameter, there’s no need for serious construction. Customers who purchase a Saniflo pumping system do so in order to add en-suite bathrooms, basement toilets, garage installations, toilets for elderly family members, and many other practical toilets that could not be added through conventional methods.

No matter where you need a toilet, you can add one with the help of Saniflo toilet systems. Even if you’ve been told that you can’t add a toilet to your home due to the fact that your main drainpipe is too far away for a normal toilet system, you can bet that Saniflo will work. Thanks to this innovative product, no new toilet addition is impossible.

You’ll also be happy to note that our macerating pumps, gray water pumps, and toilet systems are entirely environmentally friendly, since they use far less water than any regular system. Saniflo’s macerating systems last more than 50,000 flushes (10 flushes per day), and all Saniflo gray water pumps come with a 2 year warranty. When it comes to installing a toilet system that won’t break the bank or the floors in your home, nothing beats Saniflo.

Waiting for the catch? There isn’t one. Even the installation is relatively simple! For those ambitious (and experienced) DIYers, click here to find your Saniflo upflush toilet installation instructions (but don’t attempt this alone without sufficient plumbing knowledge; if you’re a novice, this is a job best left to your plumber). And once it’s in, all you have to do is enjoy the convenience of another toilet where you never thought you’d be able to put one!

  1. I am a independent engineer and I work on most makes of macerators, yes there are some copycat makes, and I would agree that the saniflo range of macerators are by far the best on the market, some of the other make even use plastic blades, to me thats ridiculouse, but as far as I know all the saniflo range use stainless steel blades, and the simplisity of construction makes them very unlikely to break down if you use them correctly

  2. These Saniflo toilets are really fantastic. I recently installed one in a below ground level semi-basement toilet and it worked like a dream. They really are a good, and fairly low cost investment for the additional versatility they offer.

    Thankis for a Great Post

    1. Hello my name is Angel we want buy saniflo..shower.toilet.sink…what distance shower.toilet sink is beter for my proyect
      We need base for shower..what are the Best .mesures for the proyect.
      Dimensions.Wide by high..thanks for you help.God

  3. What a brilliant concept! Kind of makes you think that every toilet should work this way, even if normal plumbing access is avaialble. It’s sanitary and pretty efficient.

  4. The Saniflo brand are the best Macerators on the market, there are other brands but they are noisey, difficult to repair and are not as the same standard as a Saniflo Macerator. The Saniflo’s are easy to fix if they go wrong, providing they are installed correctly and have sufficient access.

  5. We have an older building where this would be perfect. We had to do a project at one of our panama city beach condos a few years ago. I wish I had this system. We practically had to rebuild the unit in order to get the bathroom in. Thanks for the info.

  6. We’re thinking of converting part of our garage into a utility and a small downstairs toilet. We’ve had 2 builders round to quote on the work and have been advised by both that we cannot have a toilet there as our drains are too deep. I asked about saniflo and was advised that this would also require a lot of work as the kitchen floor (kitchen is behind garage)would need taking up for the pipework to be fitted which would also mean more expense. I can’t get my head around this as my understanding was that you can fit saniflo easily anywhere. The builders came highly recommended and seemed to know what they were talking about but I’m completely baffled!!!!

  8. I Will have to come back again whenever my course load lets up nevertheless I am getting your Feed so i could read your web blog offline. Cheers.

  9. I just moved into a flat with a saniflo and its a nightmare. Not only are you very limited of how much paper you can use as it can block but ive used my apparent new saniflo for the last 2 weeks very responsibly and when it flushes the blades are so powerful and noisy it literally rocks things, the whole bathroom floor vibrates and the toilet moves. It goes off on its own, its just a matter of time before the whole thing blows open. Terrible product.

    1. Sorry to hear about your bad experience! Did you have the unit professionally installed? Have you gotten it checked for defects? We have not had complaints like yours, perhaps you got a faulty unit.

  10. Can anyone help. We have a saniflow installed for the first time. We have a sink and a toilet connected, however we have filled the sink with water and then pulled out the plug, we have done this 3 times but the pump hasn’t kicked in. Are we doing something obviously stupid.

  11. We have a saniflow system in my sons room. At first it worked well, but it blow’back sometimes and the smell is awfull. We contacted saniflow and were advised to put a smaller pipe in it was ok for while but the smell is back. Help

  12. My husband has had a stroke and is unlikely to be able to get upstairs for the loo when he comes home from hospital. We have a space in the hall where possibly a Saniflo loo could be installed. I need an engineer/plumber to come and have a look to see if it can be done please.

    1. Hi Irene, sorry to hear about your husband’s stroke. We sell the toilets, you’ll have to look for a local plumber in your neighborhood to do the installation.

  13. I was thinking of getting a saniflo system fitter, do you need to
    have a sink fitted to? As I’ve only got room for the toilet.
    As this will be in the kitche .

    1. Your toilet will be in the kitchen?

      You can install the toilet only. Consult your local plumber for more information on the installation process. Thanks for your interest!

      1. Hi Yael, thanks for your prompt response! I have another question: there are some pumps that attach at the back of toilets (up-flush?), and they usually come in kits. Do the sani-flow toilets work with other brands of macerators and vice versa? I realize they are meant to be used together, but I’m a curious person 🙂

  14. I am interested in installing a toilet in my garage and these units look like they would fit the bill. I live in an upstairs condo with the living space over the top of my garage. The plumbing for my upstairs laundry actually pipes over and into the neighbor’s garage. It’s just the way these units were built. I have no existing plumbing into my own garage. So do I need at least a sink already down there for one of these toilets to work?

  15. I would like to install the Saniflo into my garage. I am on septic but the garage is a lower level than the septic tanks which means that the pipes from the Saniflo would run up hill. Will this be a problem?

    1. Hi Carol, I believe that it shouldn’t be a problem but double-check with your plumber or installer to be sure. Good luck and enjoy your Saniflo!

    1. Hi Bob, we suggest that you contact an experienced plumber to ensure that your installation goes smoothly and works with your specific layout. Good luck!

  16. Help! I have a Saniflo unit installed in my en suite bathroom for a few years now but just lately it cuts in intermittently, 2 or 3 times during the night which is very annoying! Can you suggest a cause/remedy/repairable?
    Many thanks

  17. Hi, I want to install a toilet in my log cabin at the back of my garden about 120ft from the house. The house is slightly downhill from the log cabin. I would be happy for the toilet to be one that paper cannot be flushed down and that is used for No 1’s not No 2’s!
    Is it doable and which Saniflo would I need?

  18. I am interested in this product. Do you know if it is a good solution until I can figure out why my main toliet keeps getting clogged?

    1. Please feel free to contact our knowledgeable sales professionals at 800.554.3210 – they will be able to answer your questions. Thank you for your interest!

    This is my first time for me on the computer ser
    ching ,so I hope I got it right. Hoping to here from someone.Thanks.

    1. Hi Dan,
      Josh, a member of our sales team who’s an expert on the topic, contacted Saniflo for you. They recommend using a separate pump for each toilet bowl. However, it has been done using a “Y” shaped pipe. A better option for this application would be the Sanicubic1 model pump:
      Hope this helps! If you need any other assistance feel free to give us a call at 800-554-3210.
