Can i solvent-weld the trap adapter onto pvc that is 1.9” od (1.5” schedule 40, not 1.5” od)?

Yes. A pipe with 1.9" OD is actually called 1.5" (1-1/2") because that is the nominal pipe size. Petersen Products and various other sites have lists of what the true OD, ID, and wall thickness are for PVC and ABS.

I bought this kit but I need a longer waste tube. Is there a different kit or can I buy a longer waste tube?

I ulttimatelychad to buy an additional piece of straight pipe and use pipe glue, washers and connectors to get it to reach the sink drsin

I think the pipe from the trap to the septic line might be too long, can I use a flexi line with your kit. My septic pipe is an unthreaded bare pipe?

The L shape pipe can be cut. So no need for a flex line.

Is the j-trap piece 1-1/4" diameter? Could I connect just the j-trap (plus a nut?) to the threaded metal elbow of the existing bathroom drain pipe?

If your existing (metal) j-trap has a captive nut to connect to the threaded metal elbow, you probably want to find a j-trap that has a captive nut. However, I think you could use this kit if you're willing to also remove the metal elbow & drain pipe and replace them with the arm included in this kit. This kit has the captive nut on the arm, not on the j-trap, and the threads are on the j-trap. It would be more "universal" if the kit were designed with the threads on the arm and the captive nut on the j-trap.
