I have problem with size reducing tee in schedule. For example 32-20-16 Tee and 20-32-16 tee are the same size (32-20-16) in schedule. how can I fix it?
Okay I misunderstood your issue, I thought it was the branch size that you were having trouble with.
Going back to your original post, with the sizes being run-run-branch the a 32-20-16 tee and a 20-32-16 tee are the same thing. When you buy the tee there will be only one version and then its up to you which way round it would be fitted on site.
