I have a 2001 SAN with the LCS. My questions is this, what exactly do the valves next to the driver accomplish. I beleive (with no technical basis) that these valves open the tanks to the outside air thereby letting air out of the tanks so that they can fill. Is this correct?

Also, one of my tanks fills significantly faster then the other (shorter piping and less resistance I suppose), and this same tank fills whether I have the valves open or closed. Also, one of the valves turns signigicantly easier then the other. Anyone else have any similar problems or experiences and is there anyway to fix this?

And I know that if I close the ball valve in the enging compartment that no water will enter the tanks, but what the **** is the purpose of the valves next to the driver? I know in 02 the valves went away, and then in 03 they showed up again under the dash (could be 04 not 100% sure).

Help if you can. Other then that this is the best boat around for wakeboarding and the cruising that we do. Love it and recommend it to all.

i also have a 01 SAN and we heart our boat. But were always confused at why one tank fills and empties alot faster then the other one.

The healm control valves are really just vents as you suggest. The allow air to escape when filling the tanks, and also allow air in when emptying the tanks so as not to create a vacuum. On the 2001 model the water comes in and out through the same valve/hole
on the bottom and so a vent is required. BKH

Our 2000 fills and empty the 2 tanks in about the same time. And with the valves closed I never noticed that any water was coming in. For me it was a problem free system and I'm aware of the problems some people has with their ballast system.
Check if the vents are working properly, take them off the ballast tank and blow through them. With the valves closed you shouldn't be able to blow through them and when the valves open the resistance should be the same.

You mean the resistance should be the same from valve to valve, not from closed to open, correct?

Yes, correct.
