Ballast Bags?

[cab13367]

So what if you remove the plug and added another fitting & hose and T it into the drain? Theoretically that should allow the air to purge as the bag fills right?

Razz,

That sounds right. I always roll up and remove all the bags to allow everything to dry, then I don't hook them back up until I am on the water so I don't have this issue. But if I was going to leave the front bag in there all the time, that's what I would do.

Sounds like a good idea. Am i correct you referring to the cap and such at the top of the bag? One ind has the Fill and Drain nozel and the other side has a screw on cap.

Any idea what adapter will fit those to attach a line to it?

Then i would just run a hose from that cap on the top section of the bag back to the lower drain line where it pumps it out of the boat.

I think pretty much any of these would apply, Wakeside Fly HIgh Ballast Fittings. I'm just going to have to figure out how to getur done!

Yup i think your right onto something there Razz. I think ill get the first two pictures. The screw in adapter and then the quick release fitting so it looks like the others. Then a T junction and some 3/4 hose and run it from the front of the bag back to the lower drain line. Hopefully that works.

I dont quite understand why only the front bag fills with air. Must be the way that drain port is on the curve of the hull in the front.

[Razzman]

I know this sounds like a pain but i would think the T should go as close to the thru hull as possible, but i dunno.

I think the thru acts like a scoop and sucks the air in. Hey! Why not just cork it up!

[mmandley]

Yea i was wondering about that too. < T it at the hull exit > See another good reason why i didn't fill in that sub with spray foam. I would need to run the tube right threw that cut out where the sub fits in.

I would think running it to the Hull exit will cause more issues with draining water. The exiting water would hit that T and then drain back into the bag making it im possible to drain then. With the T at the primary exit point on the bag then it would be less likely to pump it back into the bag?

[Razzman]

I dunno, those T's aren't that thick are they? I'd use the ABS ones from an auto parts store. Where's Jason when you need him?

[mmandley]

Well no there not that thick but wouldn't you want a 3/4 so you dont limit the drain flow?

Maybe get one of those angles Ts so the air is mixing at a 30 degree angle. So the water flowing by acts like a Vacuum and helps pull any air and water out. Ohh thats a good thought if i do say so myself. LOL

[Razzman]

Ok i think it's getting a little deep here! LOL!

Yep, that's the solution. W736 in the spare hole, W742 on to that, and then Wye it into your drain line. You could install a check valve, but if you use a Wye fitting (and not a Tee) it shouldn't be necessary.

Amazing (and a little surprising) to learn how Moomba set their systems up from the factory.
