So I purchased a pair of launch 440lb side sacs and they would not drain out with a hose attached the the lower ports as well as the higher ports? Other sacs I have used drain right out, am I doing something wrong? I know the line is not clogged due to the fact its the same one i use to fill. thanks guys

When you say "same one I use to fill" are you talking the through hull fitting that's below the water line? If you're trying to pump out the intake there may be too much pressure for the pump to overcome? It still should work but...I would think slowly. You should be draining above the water line.

I fill from the bottom of the boat, I pump the water out of an AUX bilge pump hole above the water line. Im using the blue fittings, this is driving me nuts??

Is the pump clogged? Is it running in the right direction?
