Sounds about right, except probably not the right coupling at the bottom. The check valve looks like it's got a 1 1/4" barbed fitting (other threaded end looks to screw right into the sump).

So you'd have 1 1/4" polyethalyne coming out of the sump/valve and need to connect that to whatever the cut pipe is made out of. The coupling posted is for PVC to PVC.

If your "cut" pipe is PVC, then you'd need a coupling that has PVC slip on one end and a threaded end on the other. Youd then put a threaded <--> barbed 1 1/4 coupling to connect to the poly pipe.


Basically assuming you've got 1 1/2" PVC as your "end point" you'd need a length of poly sump hose (1 1/4"), the valve, and 2 coupling/adapters
