2008 22SSV Ballast Pump

Hello, I am new to boating forums, and also to Supra. We recently purchased a 2008 22SSV as an upgrade from our 2013 Yamaha AR190. The wake is awesome and rampy, but the ballasts take forever to fill. From what I have read, there is only one pump, and it only pumps about 8-9GPM. Also, I wonder if a valve is worn out because as i am filling either of my stern bags, the bow bag still fills... I am assuming that the sprinkler valve needs replaced, but I am not sure where it's located, and any help would be excellent on this matter.

To the pump, does anyone have ideas on a pump replacement that could speed up fill time? 20-30GMP would be excellent, but is that reasonable?? Thanks a lot for your help, and I am looking forward to being a part of the forum.

If you fill in motion it makes a HUGE difference in fill time!

Upgrade to wakemakers setup that is like the newer boats with 3 reservable pumps! I did on my 07 24ssv and fill 1100 x3 in 12 mins and is a much cleaner install vrs the sprinkler valves.
