I was wake surfing earlier today and realized the rear ballast was draining out of the drain holes of an 16 A20. The pumps were not on, wondering why this is happiening and if this is how the new system works? Thanks :)

A little bit will drain out of the vent line, or is it completely draining?

Same thing is happening to me on my A 20. The drain pump is not on and water drains out of the drain holes. There is no vent on the rear ballast so water is pushing through the pump. Was at the dealer today and they said if I extend the hose and put a loop in the drain hose it should solve the problem, but I'm not buying into it. This happens to both the pnp drain and the stock hard tank drain. Anyone have a way to solve this to get most out of the ballast?

Your dealer already gave you the correct answer. You need to loop the hose higher.

Think about it. Water seeks it's own level, and when you are planing off and the boat is tipping up, the front of your ballast bag may be higher than the thru-hull. So the water will run out of it. Once you loop the hose higher than the bag, then the water can no longer run out.

This happens to me as well, I believe that when the sacs are full, there is a lot of pressure in the bag. The pressure ends up relieving itself because it's not a closed system.
