I finally got my ballast system installed, I'll post pics when I take them later!

However, the one problem I had with it was the front bags filling while the boat was moving and the pump was off. Anybody have any ideas on how to combat this? I'm running a T-manifold with two pumps coming off of the drain plug in the hull. The hoses for both pumps run forward about 6 feet then one goes through the gunwale to the back and one splits into the two front bags. The hose going to the two front bags is the one I have a problem with. I was confused about why they fill and not the bag in the back of the boat but one theory is that the hose going to the back of the boat takes a pretty high path to get back there (up around steering wheel height) and the hose to the front bags does not. Think if I just make the hose going to the front bags take a higher route it will be an easy fix to the problem?
