Vent / overflow on front sac

[04OUTBACK]

So i am going to switch my front sac with one of my back sacks as the back sacs have a fill/drain ports on 1 end and another fitting on top. I plan on running a hose off the top front of the sac to a thru hull fitting. this should allow for venting/burping the sac and also it should flow when the sac is full.

ANy issues with that thought process? as long as the thru hull is above the line of the sac, it should not freely drain, correct?

Correct, run the vent off the top of the bag and up near the threw hull and add a Y connector and your golden

don't forget the check valve to keep the water from rolling back in through the vent as it's draining.

I think I need to do this too. My front bag fills up with air. Can you use the existing thru-hull and a Y connector? If you add a check valve in the vent line, will air push right through it and get out?

[sandm]

I wouldn't see why not. the water is going to force the air out the first available hole, the venthole. should be a case where once you see water coming out, you're full.

my original plan was to add another through hull, but, if I understand correctly,
If I put a check valve on, I can use a Y and use the current drain for front?

Check valve go above or below the y? Above I would assume so it does not flow back down the other side of the Y?

Thanks
Picking up the boat from Winter Jail today hoping to get to work on some of these chores!

Grab one of the wifes wine bottle corks for the exit thru hull for when your towing, when ya get to the flint pull it out. Simple/cheap
