Installing a Flexible Tub Drain

[trombonemann]

I have a Watco Flexible Drain that I am installing on a bathtub renovation. Need to move drain over to accommodate larger tub. The Schedule 40 PVC I need to connect it to had a slip-joint with a brass drain assembly previously. The Watco has a female connection that a 1 1/2 Schedule 40 PVC pipe would fit. Can I install two slip joints to connect these using 1 1/2" under sink PVC to connect Schedule 40 PVC?

What model number waste kit did you get? I typically wouldn't trasnsition from sch 40 plastic to tubular/slip joint downstream.. What material is the trap made from?
