When you are filling the sacks how much of the pump do you put in the water? IE just dump the entire pump in the water or just enough that it pulls water?

we usually just throw the whole pump over the side so that the whole pump is submerged. we have done it like that for years and never had any problems. not to say its the right or wrong way but it works for us. my :twocents:

same here, 3 years and still works fine. Those pumps are made to be submerged, plus it won't suck any air this way and pump water the fastest.

Instructions say that you may need to submerge pump for it to start pumping.

That is to develop enough net positive suction head for priming purposes. I throw mine overboard and any extra hose that may be near by as well.

throw it in and let it suck. also just hook it up to the outlet on the sac and pump it back out. lift the bag to keep water to it while draining.
