building a ballast system pump help
 

Ok I"m putting togeather a 3 bag system in my boat. 2 in the rear one in the ski locker. Will one ballast puppy pump fill all 3 bags? how should I run the hoses? just T the lines off or run from bag to bag?

I'm going to run 2 fly high 400lbs in the rear and the one in the ski locker is yet to be determined.

I planned to run a line in the bottom to fill drain, and a vent out the top of each bag over the side.

I would split off right after the pump instead if running bag to bag. I would also put a check-valve in each vent/over-flow line. This will keep the pump from sucking air if one sac empties before another.

ok.. I will have to see if the fly hi sacs have a valve like that.. I thought maybe they did... If not is it something I can buy that screws in?

I did the same thing with four bags but I made a mainfold right after the pumps to divide the water up. So I could control what bag I wanted to fill.




I'll find a picture of it at lunch for you.

a manifold system?? that sounds complicated! but cool!

not really, All you would need is 3 valves teed into one pvc pipe. Then run your lines from each valve to a bag.

ah ok! I can handle that! you just open and close the valves to fill each bag you want. a picture would be great!

Every thing here was bought at lowes except the pump. I cut a panel to fit in front of the engine and wraped it in carpet. The black pipe above is just PVC painted black for some reason. The switch for the pump is wired in the panel on the far side you can't really see it but this lets you work everything from one place. Flip the switch and open a vavle.

nice setup man..

ah very cool! I think I will do a similar set up. What size valves and hose did you use? 1 inch?

Yep 1"

did you tape all the treads or use pipe sealent so it doesn't leak?

also do you fill drain out of the same pump?

On the threaded one's I used tape the rest was the sealent.

ok cool thanks!
