looking to replace my p trap system under the kitchen sink. It’s old . The actual pipe that suppose to curve up to the sink drain is rotted under so I need to unscrew the nut and replace it .
I prefer to replace the whole thing with PVC . How would I go about doing that? What would you do?
It looks like your trap arm is soldered to the house drain pipe in the wall. I suspect the in-wall pipe is copper DWV, as I see no threaded joint that is the usual point of attachment for "PVC" under-sink tubular drain systems. The easiest thing would be to use a rubber coupler sized to fit 1 1/2 tubular drain, between the solder joint sleeve and the new trap arm. (PVC in quotes above because actual PVC tubular drain parts are largely a thing of the past, which is sad because they were vastly superior to the mostly polypropylene stuff universally used nowadays).
