As I was replacing my flo-rite valves with the TH valves it dawned on my why my center ballast tank fills quicker then the rear tanks (except when motoring). The center tank has the valve after the pump, the rear tanks have the valves before the pump. The little valves do more harm to the flow when they are on the suction side of the pump. I also noticed that the pumps are mounted so they can trap an air pocket which explains why my port side rear pump did not like to prime when stopped.
So today I moved all the pumps so they screw right into the ball valves then mounted the new TH valves downstream of the pumps. I feel confident that they will prime easily and fill the tanks faster.
It appears that the factory does not take advantage of the two peice aspect of the pumps? There was a 3/4 close nipple and a 45* on the front pump so you could spin it on the through hull. I was able to remove the nipple and 45 then screw the removed base right on the ball valve getting it lower and thus better water.
Now I just need to finish putting the stereo back together so I can go test it out.
