I just bought a couple of sacs for my boat, but I didn't buy a pump. I planned on making one out of a bilge pump and some hose. I started thinking about it last night, and I thought of putting a Y-Splitter in the line for one of the rear tanks, and running the second hose out from under the rear seats so that I could use it to fill the sacs. The Y-splitter would have to have the capability of turning off each side independently. Has anyone tried that before?

The only thing to remember is that the water flow to the side of least resistence. As a result if one hose is longer than the other the shorter hosed sac will fill first. However you can adjust that with the valves Good luckNautiqueless in San Diego -
ballast splitting
Jeff,
I own a 2001 super air, which has the air valve system with fill/ empty ballast pumps. The only thing I didnt like about the boat was the ballast system, filling and emptying via two pumps, plumbed together, filling through and emptying through each other.
I teed off the intake for the pumps and added another fill pump, plumbed it to fill my starboard tank, cut the hose between the two original fill/ empty pumps and made them dedicated to the portside tank, so its a fill/ empty independent of the other tank. I also added another pump to the starboard tank so it can empty independently also. I kept the air valves hooked up as a vent, etc. and now empty via the tugboat look, or peeing boat, as my son would say.
so yes you can tee off the intake to your pumps, but I would add another pump to your tee vs filling from the rear pump.Comment

sounds about how my '02 came from the factory.
A dedicated fill for each tank.
A dedicated vent with no pump in the line.
A dedicated empty out the side.
I have three holes near the deck on one side (ballast empty, ballast vent, and bilge) I have two holes on the other rear side (ballast empty, ballast vent), three holes near the deck by the cockpit (same as three in the rear), one hole on the port side for the dash cooler drain, and four holes in the bottom of the boat (engine intake, and three dedicated ballast intakes).Comment

Re: Splitting Ballast Intake Line
If your concerned with speed of the fill, you might want to upgrade to a slightly bigger "Y" joint. Maybe something made out of PVC. I have 2 different 1100 pumps with different size connectors. The smaller connector takes a bit longer to fill than the larger one.Originally posted by NautiqueJeffComment

Here is what I did with some success and failure.
I changed all my tubing to 3/4" Here's the reason, from the factory the pickup to the rear tanks is 3/4" then from the pump the tanks it was 1" I figure you can only pump as much as your smallest tubing. So, I swapped out for all 3/4" easier to find parts for.
I then replaced the pumps for 1100gph pumps and had to do some retro fitting for plumbing sizes but, ultimately, I'm still at 3/4" I run it up to the tanks, put a "Y" splitter like you show (garden hose "Y" splitter) run one to the tank and then one to a fat sac on top. Then did the same exact "Y" splitting on the overflow of the tanks. I then plumbed a pump on the other connector on the fat sac then up the 2nd "Y" to the overflow stock plumbing.
When filling I have to fill either the tank or fat sac, if I leave the "Y" both open then it'll continue to fill the tank and never fill the fat sac, less resistance. So, I turn off the tank and fill the fat sac.
My biggest problem I've had is trying to get the empty pumps on the fat sacs to actually empty but, haven't tried flipping the fat sacs over so that the connections are down.
The other problem I had was that I almost blew the storage cover off from over filling the fat sac. So, I have to keep an eye on it.

Wake Junky - If you are trully using Fat Sacs, I would recommend swithching to Launch Pad sacks they have many mroe openings from which you can connect your system to. And they have drains located in the bottom of each sack, which should be a benefit to what you are attempting to do.2001 Super AirComment

I would opt to try another fat sac but, I've already forked out 2 bills for custom letsgoride fat sacs which are the thickest I've seen.
I am thinking of just flipping the bags upside down but, then I have the problem with burping. I figure if they are completely empty they shouldn't be able to take in air.
