Is Saniflo system problematic for terrace house?

We had a Saniflo installed when we converted the waiting rooms of our station into a self catering unit.  It worked perfectly until the day a young couple decided that one would have a shower, and the other would use the toilet, they were flooded out by the toilet. Can only use one source of water at a time.

Have flushed the toilet and run the shower at the same time many times.  

It might depend on the unit you get.  There are different ones for different reasons - you'd get a different one for a full ensuite that you would for just a toilet, so perhaps it was undersized.  

There's a dedicated company that service and repair them.

would a saniflo handle all sorts of stool, especially those on the hard side like rocks?

Mother in law installed one many years ago. I guess we must be due for a catastrophe soon, because it’s never been serviced. 

I would just point out that it runs to pump out the waste from the bath and basin, as well as the loo. So, the noise is on for a lot longer than you might expect. It would be worth listening to it running in the neighbouring rooms, particularly the one underneath.

It is as valid now as it ever was.

Just pause and ask yourself why a Saniflo is needed...
Because the pipes away from this toilet are too small diameter for toilet waste...? Why didn't they simply install proper diameter pipework?
Or is it because there's too many, too tight bends?

Does mincing everything that goes down that loo sound like an optimal solution to you?

The other usual installation situation is because the toilet is below sewer level. And we all know what does not roll uphill.

A saniflo is a great deal more expensive and involves a lot more labour than installing proper diameter pipework.  Nobody would install one as a bodge.  

If the only suitable place for an extra loo is a long way from the drains and a fall can't be accommodated through the house layout (or the joists run at an angle to the required route) then a macerator is the appropriate solution. 

While I'm sure this is generally true, our new house had not just one but two saniflos that were installed as bodges. It cost us just over £2k to have one changed and the pipework put in place for the other (we'll connect it up when we replace that bathroom rather than tear up the tiled floor now). It only cost that much because the paving slabs and tiles to the front and side of the house had to be taken up, very carefully and slowly to avoid breakages, to connect up the pipework. I'll never understand why the previous owner chose to have two macerators installed when access to the soil pipe was so easy.

I watched too many episodes of Homes Under the Hammer in the past to ever have used that 'nobody' statement sensibly.  😂

Slap on the wrists for me.
