I think the manufacturers recommend not putting a tap Tee in over half the size of the Main. For example a 3 inch tap is the biggest you can put in 6 inch tile, and 5 inch tap the biggest you can put in 10 inch tile without affecting durability of the main.
This is what my supplier told me years ago. |
