I'm sure this is a simple thing.....had additional rear ballast bags added to the rear. First time trying it this past weekend, they only seemed to fill up about a quarter of the way and then the water started running out the side. Same as it always did before when the rear factory ballast tanks were full. I noticed an air vent on the top but didn't want to mess anything up and just left it. Since then as a result of this forum, I understand I need to burp the bags. But still curious even how the system works? Do the factory ballast fill first and then to the bag? Or does water go through the sacks and then to the factory ballast? My dealer did the install so I'm assuming it's been done right and that I'm more than likely doing something wrong. Any help much appreciated?? Thanks all.

The hard tank fills first then starts pushing up in to the sack, the water you see coming out the side is probably the hard tank overflowing a bit as the bag gets fuller. I would add vent lines off your bags also so you don't have to manually do it every time. You can do this by either taping into the 3/4 overflow off the hard tank or tap into the drain line off the hard tanks. ImageImage

Okay that's kind of what I figured. I did see your post you copied for me previously. So if I vent the sacs while it's filling and overflowing from the factory ballast then it will stop venting water and begin filling the sacs more?? The key is venting the air in other words correct??

You can give it a try. Bleed the bags as your filling, that way the air is being pushed out as it fills, just don't forget about them filling [emoji6]

A lot of us rerouted the vent and tied it to the top of the sack itself... works great on my 15 T23.

Kinetic vent from drip depot or Amazon is much simpler and works great and costs 7-15$
Use the o-ring from your plug on the vent cause they don't come with one in the unused top fill/vent hole
