I have a cutsom sac for the port side similar to an Enzo sac, but built to my Tige's dimensions. It is connected to a reversible positive displacement pump from make-a-wake. We spend a great deal of time each session riding the starboard (aka dark side
) On the starboard side I have two sacs and I fill them with a Tsunami and then empty them with a tsunami as we fill the port side.
I'm ordering a custom sac for my starboard side, but I'd rather not buy another $650 system just to fill the dark side
What I'd like to do is build a system using the existing pump that will allow me to select where the source of my fill will come from, lake, port sac or starboard sac. I also want to be able to select where to direct the empty - port or starbord sac OR back into the lake. I'd love for it to be "smart", so that if I am filling the port side and the starboard side has ballast, the system would draw from that sac first.
AND I want 5 million dollars to build that system
Any engineer types out there that can design such a system with less than 5 ball valves?
