Since we were replacing the garbage disposal that died recently (fairly easy - already done) we decided to replace the convoluted drainage pipes under the kitchen sinks too. The argument we are having concerns the proper placement of the P-trap.

The wall drain pipe is 2" and is located on the right side. The garbage disposal and the dishwasher are on the left. I think it would be fine to run a horizontal pipe from the disposal and have the P-trap on the right side (by the wall drain pipe). My husband insists that the disposal should drain directly into the P-trap. Is one way better than the other?

I want to do this correctly the first time, so I'll do without my kitchen sink for a day or two until I can find out the best way to do this.

The "best" way, (and the correct way) is to cut the old drainage back to the wall stub out, wye out and install a single trap for each tub. We install our disposals in the left hand tub. Good luck, Tom
