    Default IBS venting hose?

    Oops meant to say "drain" hose in thread title.

    So ... Installed the IBS system from Wakemakers over the weekend and noticed that the drain hose is connected to the top of the bag. It drains fine but is that normal? Seems weird to me to have a drain on the top of the bag.

    The problem I have with it is when it is full, the 90 degree elbow on the drain hose prevents the front seat from sitting flush.

    Any ideas?

    You should be able to drain it from either leg.

    You were correct in the title. That is the vent hose, unless you hooked up your hoses wrong. The hose just below that at the bottom of the bag is the fill/drain hose. Make sure you have the fill/drain hose in the correct spot. Some guys live with the seat popping up, others will actually drain some of the water out so that the seat goes flat. Are you venting from the nose of the bag or the top right rear leg?

    I too live with the seat and cup holders popping up. If you have people sitting up there, that will keep the seats down - otherwise, I want all the weight I can get.

    The cup holders have a drain connection which was not used on Moombas. It is pretty sharp. My cup holders were pretty securely attached, so I broke the adhesive tape free and ground off the drain nipple. Just breaking the adhesive free would have been fine.

    Follow up question. Are guys venting from top of the nose or the top of the right rear leg?

    Default IBS venting hose?

    I vent from the top of the starboard leg because that is the closest spot to the thru hole. I do on occasion loosen the plugs at the top and port legs to let air out if I feel there is air in the bag. Only takes a few seconds, and I'm not worried about it enough to install/move my vent.

    I followed Joe's model and am venting from the nose -- never had an issue with either the filling or emptying. And with the check valve these bags both empty completely flat and better than my rear locker bags that don't have check valves!!

    I vent from the nose. I figured that it would be the high spot, especially underway. The vent line from my center bag reached the nose of the IBS so it was really easy.

    vent from the drivers side leg, we only surf, so that made sense as it would end up being the high spot
