Finally getting around to setting up DC.

I purchased used Oneida V3000 yellow version off CL.

I had a buddy that runs local supply house get me all the SCH40 PVC 4 and 6 inch pipe, WYE's, 45's couplers / reducers that I couplers that I ever could possibly need.

So the last piece of the puzzle is what blast do I need, that will work with 4 inch SCH40? From my readings it seems all vary OD/ID and I don't want to monkey around and just want tried and true that will work with 4" PVC.

Any recommendations and thanks in advance!
