About 2-2.5m apart. But WC2 is only temporary until the house is built.

Thanks PeterW. So I could probably use a pan connector with waste adapter on WC1, instead of using the top boss on the branch. Would that work better?

After some advice on a FloPlast double branch please. Ive got my soil stack coming up through the ground floor of my new garage from a store below. I need to connect a toilet and basin and then in a room next door connect up a temporary bathroom (toilet, bath, sink). I was hoping to use the double branch to make all the connections but now I'm not sure if I should be using separate boss connections above/below the branch for basins/bath. Is it ok to use both boss connections on one side and both pan connections?
