Hello, I've been a long time lurker on this most excellent forum - so much great advice! I'm in the throes of a master bath remodel, replacing one of those old built-in whirlpool units with a freestanding tub. This required me to move my 1 1/2 tub drain line over one joist space. Due to placement/etc., I went with short sweeps but now I'm having second thoughts.
Am I asking for trouble/should I redo with long sweeps, instead? this might jog my layout slightly (moving the drain an inch or two further away from the joist). Ugh.
I've found the aforementioned (in other posts) table 706.3 (uploaded) from the IPC that states that short sweeps can be used for waste less than 2" but of course I'm in Minnesota and they are now using 2020 UPC code with this opaque statement:
"Horizontal drainage lines connecting with other horizontal drainage lines shall enter through 45 degree (0.79 rad) wye branches, combination wye and one-eighth bend branches, or other approved fittings of equivalent sweep."
