Yep, the check valve is the last thing in the system before the thru hull fitting.

Got it and thanks for confirming. My boat is 1.5 hours away so I'm trying to do this upgrade in one trip with everything I need heh.

I should have realized I could have just stuck my finger in the check valve to see which way the flap went but yes blowing also works lol. The housing is also larger on the side the flapper has to fold into so that also should have been a clue for me lol. Regardless I went ahead and marked the flow direction so I don't forget when it comes time to install next week.






Based off your recommendation I realized I did not have enough bag and hose fittings to do two vents per each rear bag instead of one so I put in an order at WM this morning for them. I also ordered another pair of 1" Tee fittings so that I could make this plumbing network below. I think this is how I should do it similar to yours. I'm going to move my ballast sensor in between the check valve and the Tee fitting. Thoughts?
