26 reviews


The Saniflo Sanibest Pro is a heavy-duty upflush toilet kit designed to work hard and keep going for years to come. Featuring a heavy-duty macerating pump, a white toilet bowl in either standard or elongated length, a white toilet tank, and an extension for installing the macerator behind the wall, this kit is the perfect addition to your home, office, or rental building. Designed to allow installation of a complete bathroom up to 25 feet below a sewer line (10 feet more than most models) and up to 150 feet away from a soil stack, the Sanibest Pro incorporates a heavy-duty grinder system to handle all your household waste, and even items that aren’t supposed to be flushed down a toilet system, such as sanitary napkins and dental floss.  Because of this, the Sanibest Pro is a popular unit for environments that you may not have control over, such as rental units.

SaniBEST Pro Benefits

The SaniBEST Pro is a system that is used to install a complete bathroom and/or laundry room up to 25 feet below the sewer line, or even up to 150 feet away from a soil stack. The SaniBEST Pro pump is designed to connect with:

  1. This SaniBEST Pro Upflush Toilet
  2. Any Sink
  3. Any Shower
  4. Any Bath
  5. Any Washing Machine

While most of Saniflo pump ranges are macerators, the SaniBEST Pro incorporates an actual grinder system.  The SaniBEST Pro is ideal for situations where you do not control the use of it (ie. rental unit, offices, warehouses, etc).  The SaniBEST Pro is designed to deal with sanitary articles that may have been flushed down the toilet; such articles may consist of sanitary napkins, q-tips, dental floss, etc.

SaniBEST Pro Installation

The SaniBEST Pro is simplicity itself to install; there are just four connections.

  1. The macerating/pump is connected to the spigot of a horizontal outlet toilet. 
  2. The toilet tank is connected to the water supply. 
  3. The macerating/pump is connected to the small diameter discharge pipe work. 
  4. The macerating/pump is connected to the electrical supply. 
Then optionally connect the discharge pipes from the sink, shower, bath and/or washing machine.

SaniBEST Pro Function

The inside of the SaniBEST Pro is comprised of a pressure chamber, which starts and stops the unit, and the motor, which drives the stainless steel cutting blade and the pump.  When the flush is activated, the water flowing into the SaniBEST Pro activates a micro switch in the pressure chamber, which in turn starts the motor.  The motor is sealed for life in an oil filled enclosure.  A common spindle/shaft drives the impeller and the blades.  The moving parts therefore are kept to an absolute minimum.  Water and organic waste matter, enter the chamber and are reduced to slurry as the blades rotate at 3600 RPM.  The reduced solids are picked up at the bottom and the impeller mounted beneath the motor ejects the waste.

The unit pumps the effluent upward to 25 feet and/or 150 feet horizontally (with gravity fall).  Once the water level in the container goes down, the micro switch deactivates.  A normal operating cycle for the SaniBEST Pro takes about 7-9 seconds depending upon the discharge pipe run configuration.

In addition, the SaniBEST Pro will also discharge gray water from a variety of other sanitary fixtures such as: a sink, a bath/shower, a urinal and even a washing machine (indirect connection).  When adding a bathtub/shower, a base will have to be constructed.  This base should be made out of a 2” x 6” (minimum) or 2”x 8” (recommended) on edge, to allow for the installation of a P-trap and the required 1/4” per foot gravity flow towards the pump unit.

The wastewater from other sanitary fixtures is discharged into the SaniBEST Pro via two 1½-inch inlets on either side of the housing.  The discharge elbow on top of the SaniBEST Pro can be rotated 360 degrees depending on the discharge installation.  A non-return valve (included in assembly) prevents back flow into the unit.

This unit has been designed with a vent connection on the lid.  All plumbing codes require connection to a vent system.  Please note that the vent system should be a two-way air vent.  The use of mechanical vents, air admittance valves or similar devices are not permitted as these are considered one-way air vent systems.

The SaniBEST Pro unit must be connected to our rear discharge toilet.  It is highly recommended for the grinder to be connected to a Ground Fault Interrupter (GFI) circuit.

The SaniBEST Pro has been certified to American and Canadian Standards.  Macerating standard; US: CSA Certified & IAPMO (UPC) listed - ASME A112.3.4, CA: Macerating Standard CSA B45.9.  

SaniBEST Pro Water Conservation

The water closet the SaniBEST Pro is connected to, uses much less water than a regular toilet, it uses 6 liters (1.6 US Gal) of water per flush.

    I am very pleased with the purchase and the quick delivery. I cannot wait to install it and have a bathroom in my basement!!
    Phil from Boulder, Colorado on Mar 27, 2015
    I have had one of these installed for almost 2 years now. The unit worked great for the first 20 months or so and then failed. While I was not thrilled that the unit had issues, I must say that the customer service has been nothing short of amazing. They are responsive, flexible, professional, easy to interact with. Very good to see that the unfortunate issues are taken seriously and dealt with promptly.
    Thomas from Georgia on Feb 27, 2014
    I appreciate your answering all my emails. Everything got here ahead of schedule, which is very nice.The installation was also easier than I thought it would be. Used it all weekend without problems. Very nice system
    Marvin from Texas on Dec 15, 2013
    System works perfectly after a year. no problems.
    Bob L. from Ohio on Jun 21, 2013
    Our tank actually arrived with a crack, I called these guys and they shipped me a new one the same day. Never seen service like it. And the unit is truly impressive. Yes, you can hear it working, but this grinder can really take care of anything. I'm a contractor so I've been messing with how much toilet paper it can handle, and really can't find it's breaking point. I'll definitiley use it on future jobs.
    Stephen G. from PA on May 22, 2013
    I wish all sales/customer service folks were this responsive. Top notch service.
    Shannon T from California on May 03, 2013
    My home repairman recommended this and I'm glad he did. It looks great, works great, and clogs less.
    Monte H. from Alabama on May 01, 2013
    Got to my house in 3 days. I was shocked! I mean DVDs from Amazon take 2 weeks to arrive. Anyway, just top notch ecommerce site all round. Thank you guys!
    Josh P. from Florida on Apr 23, 2013
    I wish I had gotten the sanicompact instead, but I didn't know if I would need a shower tap onto it as well, so I just went conservative.
    Brandon B. from Alabama on Apr 09, 2013
    So grateful for free shipping. It must have cost you a fortune, but thanks for saving me a bundle!
