my toilet goes into ground i need another 4" pipe

[smudge70]

Hi Can anyone help, i have a light idustrial unit and have one toilet that
at present goes straight through the floor, the problem i have is that i need to add another 4" soil pipe to this because i need to install a commercial washing machine, what is the best way to do this, is there a way of removing old toilet ? and putting some sort of fitting one that would allow for the toilet and a seperate 4" soil pipe and how would this need to be vented?
i welcome anyones comments, many thanks,

Can you not dig it out and put a branch in? What is the waste requirement for the new washing machine?

Hi Thanks for the reply, the machine has a 3" waste from the drain but should run into a 4" pipe, the toilet at the moment has a bend from the rear straight into floor
thankyou

Sounds like you'll need to move the loo forward a foot or so and connected a swept branch in between the ground and the loo so that the washing machine can connect - although i can forsee problems of syphonage and/or blow-back

could you not move the toilet ?

i am thinking pull the toilet out, connect new pipe, and "split" new pipe one way to w/m the other to the toilet in a new positon, but the same way it is now

Or since i presume there must be an inspection chamber, run new pipe to this?

Or I'll get my coat

Hmm. So can I.
