Frequently Asked Questions

What size pipe should I use for the discharge?
This will depend on the product and how far the waste needs to be pumped. Please refer to the installation instructions.

Can I put a dishwasher/washing machine/kitchen sink through a macerator?
No, building regs do not allow for the potential cross contamination of black and grey water waste in a domestic unit also the potentially higher temperatures coming through may cause the thermal cut out switch on the unit to activate and cause a flood. However, if using a commercial unit such as a Sanicubic etc. then it is permissible.

Will I need to fit an Air Admittance Valve (AAV) to the Saniflo?
That will depend on how the discharge pipe runs away from the product. If at any stage there is a vertical drop on the discharge pipe of more than a metre then one may be required. By increasing the diameter of the discharge pipe at some stage you may negate the need for an AAV. An AAV should not be fitted to the air vents on Sanicubic and Sanifos units as this will hinder the operation of the unit.

What size fuse do I need for a domestic unit?
5-amp fuse

Why can I not use 22 mm pipe for the discharge of a Sanivite+ or Sanispeed+?
Because they are pumps and not macerators so the output from them is higher than a macerator.

How do I fit the European adapter?
Some Saniflo products come with a 22/32 mm European adapter, to use this we recommend securing the smaller end inside the discharge hose with the metal adjustable clip, the larger end is designed to be solvent welded inside 32 mm pipe, apply adhesive to the outside of the European adapter and push it into the 32 mm pipe and wait for adhesive to set.

Can I install a domestic macerator slightly remote from the back of the WC?
If the macerator is going to be on the same floor level, then yes but no more than 200 mm away. If you are installing a Sanipack Pro Up with a wall hung WC, the Saniflo unit can be up to 500 mm away.

Can I run the discharge pipe from the Saniflo externally?
Yes, you can but we would recommend increasing the pipe size and insulating the pipework.

What is the discharge pipe size for a Sanifos?
50 mm o/d and we recommend the use of PVCU.

What is the minimum water pressure required for operating a Sanicompact?
The minimum water pressure for operating a Sanicompact is 1.7 bars. If the water pressure is lower than this, we recommend installing a traditional toilet bowl, behind which you can install an adaptable macerator like the Saniflo Up, Sanipro Up, etc.
