View Full Version : Center locker bag to Nose bag piggyback

05-11-2010, 05:52 PM
I have a gravity games bag in my center locker and want to piggyback off of the drain side to just fill the nose bag. And then run a drain off of the nose bag to the thru hull.

I know this has been done on here but I am wondering where the "check valve" is supposed to go, (for venting I think)??

and does anyone have any pics of how they routed the tubing from the center locker to under the front seats??


ps I have an 06 outback V

Somebody was talking about this the other day. Let me see if I can find it.

Morgan. You need a spring check, and it needs to be installed on the empty line of the floor sack. What it does is create just enough back pressure to re-direct the water to the bow sack and fill it rather than just push out the empty line. When your empty pump for the floor sack is on it has enough pressure to open the spring check and empty the bag.
You will need to add another empty pump for your bow sack.
