I need to rework the plumbing under my kitchen double sink. Currently, it consists of one brass drain pipe along with all ABS pipe and compression joints. Can I replace the pieces I need with their PVC counterparts or will there differences in diameters not allow this.
My experiance in the UK is that compression waste pipe fittings are pretty tolerant about pipe sizes. For example a "40mm" compression fitting will clamp down on a pipe that is anywhere from about 40mm to 43mm in diameter.
I don't know if compression fittings sold in other countries are similar or not.
