I ran across this diverter valve at the local West Marine and it gave me an idea. When filling the 750# surf sac that most of us use, we typically are not filling the sac on the opposite side. So what if we installed one of these diverter valves on the fill line to the opposite sac and run a second fill line from it to the vent hole on the 750# sac? Then when you are filling that sac, you turn on both the rear ballast switches and turn the knob on the diverter valve so that the bag is filled from both ends.
Those with the stock system will see a moderate improvement since the stock pump is now filling the sac via two hoses but those that have gone to three separate thru hulls and three separate pumps should be able to cut the fill time in half. This requires that your 750 # sac be completely empty before you fill though (which mine always is) since there won't be anywhere for air to go.
The diverter valve is a little pricey at $67 but you can buy the same thing in brass for about $30. Search 3 way diverter valve.
Has anyone done this already?
I am going to incorporate this into my ballast system upgrade.
