bags not emptying

[Birdman]

so i bought some 750# sacks from wake makers and they never really fully drain got more than enough time on them 8 mins. just wondering if I'm going to have to live with this now or if its something maybe my dealer can take care of when its in there this fall.

Are these being manually filled and drained with a W709 pump kit, piggy backed on to the factory setup, did they replace a hard tank that was in the locker or did you do a ground up custom ballast install?

add check valves, but understand that they don't always drain 100% empty without having to pop the hatch and move them around a bit.

[blackcup]

mine do the same everytime. at the end of the day i just let the pump run and move them around to make sure they are 100% empty
