The ACO drain comes with a white PVC clamping drain and it has a compression collar for the tail piece of their linear drain channel body. Both the ACO PVC clamping drain and the Watts ABS clamping drain are approved drains. Both have cUPC engravings. Both meet Canadian standards.
When the inspector comes to check your work the first time is for the flood test. He/She might have been out prior to inspect the drainage pipes and inspect the 200 psi pressure test. Once the flood test is inspected your golden and you can complete the reno (assuming that the framing, electrical, low voltage, HVAC and Insulation inspections are in order).
I make it a habit now to print off the IAPMO Certificates for the drains I use and the waterproofing products. There is a high chance that your inspector has never seen one before.
