Minimum arm length for a p-trap is 3" (for 1 1/2" pipe) To me it seems impossible to slope it | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

So how do you slope the trap arm for a shower drain especially when the drain is close to the pipe (so the trap is min 3") As per the below diagram if you try to slope it using the arm segment that will compromise the glued connection between the arm and the trap as shown in this picture


In my case I have this. I am not sure if the part of the wye that connects to the trap arm is counted as part of the trap arm in this configuration...
