Hi KsGal - This drain is not compatible with Waste King disposals. Please let us know if you have any additional questions, thanks!
Nope but there is an ORB basket strainer for drain only.
I thought the same thing. The basket just lifts out
No, that is built into garbage disposer. The basket has a rubber stopper on the bottom if you want to fill the sink, you push that stopper down into flange.
No unless you are talking about pipes. Each is the same size
