The Wasteflo WC3 Macerator is a great product to choose if you're looking to transform any area into a cloakroom, complete bathroom suites or ensuites in your home. The slim design allows it to be fitted nicely behind a WC whilst still allowing room for the cistern to be fitted against the wall, wihtout the need to use battens to make it fit. The smart watertight cassette unit allows for easy removal, maintenance and cleaning of the macerator's working parts. All of this can be done without having to remove the whole toilet, cistern or pipework.

If you're aim is to create an additional bathroom in your home, then this Wasteflo WC3 macerator would be the perfect choice for you. The job of a macerator is to take the waste from your toilet to the main sewage pipe. This makes it even easier to install a toilet in any room of the house, maybe in the loft conversion or basement. This Macerator is manufactured to the highest of standards as it is by Stuart Turner, however, if you do find any factory defects, you're covered by a 2-year manufacturing guarantee.


Stuart Turner Wasteflo Removable Cassette System

Wasteflo Super-Slim Design

Super-Slim Design

The unique offset design of the WC connector allows the Wasteflo to fit easily behind the toilet pan without pushing the cistern away from the wall.

Traditional designs often require an unattractive wooden batten to hold the toilet cistern in place.

Stuart Turner Wasteflo Helical Blade


Inverted 4 Cutter Helical Blade

The Industrial 4 Blade Inverted Cutter is an innovation, designed specifically to overcome the jamming problems of traditional 2 blade systems.  It combines four inverted, hardened steel, cutting blades with a powerful vortex pump. This design dramatically reduces the chances of blockage and jamming caused by foreign objects in the toilet.

Stuart Turner Wasteflo Adjustable WC Pan Connector


Adjustable WC Pan Connector

Standard rigid pan connectors require the height of the toilet waste outlet to be186mm high in accordance with British Standard BS EN 33:2011. This is great in theory but with an increasing number of toilets coming from European manufacturers or imported from Turkey, Egypt and the Far East many toilets will not have the waste at this exact height. The unique Wasteflo adjustable pan connector will fit any height of waste outlet from as low as 164mm all the way up to 196mm

Stuart Turner Wasteflo Standard Plumbing Connections


Standard Plumbing Connections

Wasteflo macerators use standard nut and cone waste fittings, instead of the cheaper metal jubilee clips used on other brands. Metal jubilee clips are difficult to clean and prone to corrosion, making them unhygenic. Pipes can also be accidentally dislodged from Jubilee Clip fittings resulting in leakage of foul waste water. The Nut and Cone waste fittings used on Wasteflo macerators result in easier to clean, more secure and more attractive connections.

    5/ 5

    Easy to order with good description and prompt delivery, slight difference in connection from unit it was replacing but all part needed included including none return valve to stop back flow on discharge pipe. Had a loose piece in the box not sure where it fitted but a chap at Stuart Turner tech department gave me instructions on how to fit it nice to know they have a help department Instructions easy to follow liked the fact it had a 2 year warranty and filter could be changed easily. So to date pleased with purchase

    Working well and good value for the money.will recommend.

    4/ 5

    Even as a non plumber I was able to fit this unit in a below ground bathroom in my garage. Ver good value and quiet operation. My only niggle is that it took careful alignment of the loo and the macerator to ensure a satisfactory leak free seal.

    Haven't commissioned this yet but it's really neat and fits snugly in our tight space. Excellent service and delivered on time and as requested.
