sorry I've posted in the wrong section
I need a little advice if you please, I've been asked to add a toilet in a room above an existing toilet, the original one downstairs has no stack and goes straight down under the toilet into the concrete floor. I suggested a saniflow but custard doesn't want one. Can I use the existing drain to go upstairs internally for the new toilet with a aav in above the highest spillover connected to the stack. And t off it moving the toilet a couple of foot one way I'm a little worried about the top flush upstairs ending up in the bowl downstairs or sucking the toilet trap.. Thanks in advance
