Dual output pump?

[rushin]

For you ballast pro's (xpjim1) , how do you think this pump would work for a two bag set-up? I found it on ebay, I think it is a 800 gph.

just to point out the obvious, it will fill both sacs at the same time unless you install 2 ball valves. These will be hard to reach though. That will work, just depends on what you want out of your system.

The Attwood Tsunami T800 pumps are only $25 bucks at many online stores. A couple of ball valves will cost you $10 or more.

ok, stupid question..... whay are the ball valves needed?

Did you use 1200's or 800's?

So you could control which sac to fill.

fill two at the same time. One outlet would fill one bag and the other outlet would fill another bag.

You would need to shut off one outlet or the other unless you wanted to fill both sacs. Like for surfing, you would only want to weigh one side.

I went with the T800's. Too many headaches with the 1-1/8 fitting on the T1200's

I am not worried about filling just one, I want to fill'em both up.

That pump will work just fine for ya.

is a check valve needed between the fill pump and the sac?

Those pumps will allow backflow, and because they are not self priming, need to be mounted as low as possible in the bilge. Because of this, they can allow the sacs to drain. If you run the fill hose with a loop, kinda like a drain trap, higher then the sac, you will probably not have this issue.

You could also go with a faster pump and put a Y fitting on your output and do the same thing and fill faster. Just my 2cents worth
