How Many Guys Run CV off releaser Manifold

[RiverValleySugarhouse]

First year on vac. So I was checking for leaks and I get a slight back flow when my single releaser dumps. I have heard of people using check valves off manifold to the woods. I am trying leader cv's on my bottom half and clear reducers on top. So would it be worth spending the money on some clear 3/4" check valves between releaser and the woods??? I don't no why the flapper in between the float reservoir part and the manifold doesn't prevent this.?:confused:

Your flapper should have a tight seal preventing the leakage of air. Check your flapper to see if there is some ice on it or obstruction. Our flapper wasn't making a proper seal our first year on our Bernard releaser and it was due to the wrong elbow/flapper installation. We had to exchange it.
