It's my portable. You can use any hose or rigid pipe you want, as long as the flap on the check valve closes from gravity so you don't lose vacuum. I used brass ½" to garden hose fittings, because I had them

Oh ok thanks for your help Jim! My discharge was a ¾ male so I stayed with that size PVC and went with a ¾" spring activated check valve that opens @ 5 PSI but it seemed a little too hard to open so backed off the retaining screw a little & it seems to open easier
