Hi All

Looking to do a 7x4 shower with 2 heads in master bath. What would the DFU be?

IL Plumbing code says

Shower stall DFU: 3 - Min Trap: 2"
Showers (group) per header DFU: 3 - Min Trap: 2"


Does this mean it's 6 DFU and a 4" Drain?

I was planning to have a linear drain

TIA

Mark

My interpretation would be a single 6 DFU trap. Which is a 3" trap per UPC, with a 2" vent
Or 2ea, 3DFU traps. 2" min trap
Hope that helped.....
