110mm Soil Double Branch - Connections

[BenD]

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?

Yes you can use a double tee as it is seen as a swept connection however I would try and get the basin to wash down the branch from past the WC if possible.

 

The bath is a bigger issue, you can use the bottom boss but I would make sure there is a good flow from the bath to it and no restricted pipework

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?

How close are the two WC's?

 

Someone will be along to mention the potential "swap contents" issue when you flush one of them.

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

Yes would be fine

Not an issue with a double swept branch like that - it is when they are used horizontally
