I am upgrading to a GG IV setup from a GG I. While running the plumbing I realized that my center locker bag does not have a dedicated vent line but rather vents through the empty line. How is the setup for the GG III system?
Are the bags vented through a dedicated through hull or are they linked to the empty line? Are there any check valves or are the lines just connected through a Y fitting?
Thanks guys.
