None of which you talk of should be flushed away macerator or not.
The reality is people do put the wrong stuff down a bog and expect it to work like a normal one, and often its up to the householder, their engineer, etc to
get the thing back working after its jammed ..I agree with you about the wrong stuff.

Reality and theory are different..we have a lady we put a saniflo in for under her stairs years ago, as she only uses it there has never been a problem
but ...these units are problematic in my opinion

That’s good.

I think you just need a fitter with more experience/ ability to think outside the box to suss this out for you.

Really, don’t go with a macerator.

Where are you located?

I thought you had to have a soil piped toilet as a main if you wre to have a macerator installed by regs.

Thanks, I’m starting to understand that there are better options to having a macerator. I’m in South Wales.

Thanks everyone for your help and advice. I am really grateful. I have posted a diagram of my ideal set up for my bathroom including dimensions and some details.
I have already purchased the suite so I would really like to make this layout work if at all possible.

Is it possible for the internal soil pipe to run as diagrammed in my picture (blue line)? It would be almost a 3m pipe with 3 bends. Is this possible to do without the risk of blockages?
Also, is there a standard ratio of fall that I would need to have? How would I work out how much to raise the toilet or lower the waste outlet?

Many, many thanks!

Is there any reason you can't run the soil pipe on the outside?
Then you wouldn't have to raise to lavatory at all?

Well, if it went on the outside then it would have to go across the front of my house and I don’t particularly want it to do that.
