New soil pipe connection

[sleptwithatradesman]

Hi,

At some stage I'll be doing a loft conversion and adding a second bathroom.

I thought joining into the existing soil pipe would be the easiest way to connect a new WC.

My existing soil connection is an odd one. I've asked a couple of plumbers their opinion and they have yet to give me an answer.

My existing bathroom (before it was ripped out!):

The existing WC with vertical soil connection:

The soil pipe:

The soil pipe has no vent on my property (it's a semi) so must be a shared vent.

My question is:
Is it possible to connect into this existing connection and run a pipe internally upwards somehow?

I'm in the process of studding out the back wall for concealed pipework so if a soil pipe can be run internally now would be the time.

cheers

You need to check part H of the Building regulations. They are readily available on line. when you get the plans drawn up for your loft conversion they should take this into account.

Sure, but do you know the answer to my question?

I guess it's a tricky one.
