921.4.1 " ...but in no case shall the line be less than 2-inch soil pipe when piping is underground." -Standard plumbing code 1994.

Table 710.1(1) Building Drains And Sewers In table minimum size for a drain line is stated as 1 1/4 inch. -2007 code

Back in '94 when we started in the trade, min. DWV was 2 inch under slab. From what I'm told by other plumbers in my area and from how I interpret 2007 code, it appears as though 1 1/4 inch is min. for a drain line under slab. I'm just saying... In 2007 FL. code, 710.3 has been omitted. If you look in 2001 code book 710.3 states, "underground piping shall not be less than 2 inches."

I think they are talking about waste arms on that one. You just cant have 1 1/4 under slab. Just seems impoosible. Here is the statement of the chart. What do you other Florida plumbers think. Yeah now that I reread it another 20 times. they are talking about waste arms. ! 1/4 you can have only 1 DFU. Note it says connected to any portion of the building drain or building sewer. A waste arm is connected to a building drain.

MAXIMUM NUMBER OF DRAINAGE FIXTURE UNITS CONNECTED TO ANY PORTION OF THE BUILDING DRAIN OR THE BUILDING SEWER, INCLUDING BRANCHES OF THE BUILDING DRAINa
