Hi all. I want to fit a new bathroom at the opposite end of the house to the existing bathroom. How do I go about getting the toilet waste to the soil pipe? I mean, is it possible to simply add a new soil pipe? Or is this sort of thing too complicated and/or expensive?
I've heard of a system that compresses the toilet waste (nice!) and feeds it through a 15mm pipe, which can then be routed to the soil pipe, but have also heard that this system is very noisy.
Any advice?
Thanks in advance.
Paul.

It all depends on a number of things, position of drains etc. Your best bet would be to run a new soil stack to that end, and cost would depend on how much digging is involved and what material your digging through.

Macerators would also do the trick as you say you just need a small pipe, but be warned I've yet to meet a human that recommends them, they really are the worse bit of kit ever designed. Forever going wrong and each time you have to put your hand in the ship to unblock it. I was unfortunate to be called out to one, it will not happen again Crying or Very sad

Thanks for your (extremely) quick reply. Thanks to your description, I think I will avoid the macerator route! Unblocking one of those babies is something I never want to have to do even once!
Looks like a new soil stack then.
Thanks again.

Go for running a new soil stack pipe if you can.

It is not only the toilet waste, but also the bath / basin / shower waste as there are limits to the run and gradient for the respective waste pipes.

Whilst most macerators cost £300 - £600, each time someone drops something down the loo - like keys, cigaretter lighters and alike - you are quite likely to need a new macerator (as not too many people want to service them!).

Most macerators I have come across use a 22mm pipe to pump the waste. Not too noisy but the room will not smell as fresh as one with a conventional toilet.

Also macerators don't last forever - with acidents and servicing I would not be surprised if it averages out around £250 a year or so.

Looking at it over say 10 years, a new soil pipe is a better idea.
