Hi can anyone help with the following.
I have an upstairs bathroom that is connected to the stack pipe which is open vented at the top.
I have a down stairs saniflow toilet that is connected direct to the drain via its own pipe I am wanting to change this to a normal toilet and will replace the pipe work to the drain with the correct size but do I need to vent this pipe or can it go straight to drain in closed pipe as I already have a vented stack connecting to the same drain.
