Hey guys,
This is my first boat with ballast bags and two of them have issues. The left one I need the most usually will not fill or when it does it's slow. Dealer says it needs a complete overhaul for like $2500, any ideas what I can try on my own first?

Also, my middle bag in the ski locker just fills on it's own when it's not even on. What could cause that? It seems like it fills whenever another one is on and weird thing is the "on" switch for that one doesnt light up when I actually try it.

I hope it's cool to be a pain and ask for help on here. I can fix things but dont quite known the entire ballast system and how it works.

Thx,
CC
