Posted this on ephatch's facebook group, for anyone else in the future that's having problems I'm posting it here:

Welp, we've been getting an insane amount of rain and I was looking forward to seeing a dry interior, but the hatch is leaking again. Nowhere near as much as before I cleaned out and snipped those drain hose connector things but still a little. The water is still coming from the same spot in the rear passenger side hatch. Any ideas of what else I could do? I'm thinking of putting some kind of rubber sealant around it and/or where the hose plugs in, and where it plugs into the quarter panel. Unless I left it without putting it back on 100% plugged in, which I'm hoping it was just a simple mistake like that, I'm basically lost. Suggestions or advise would be greatly appreciated.

For reference these are the drain hose plugs that go into the quarter panel.
