Hi Josh, It seems strange, isn't there an overflow / vent chrome cap on the hull about 1 foot right under each tank filler? Also, don't you have the "Gardena" control manifold somewhere near your fresh water pressure pump? With the manifold you should be able to decide which tank gets used when..
If your boat doesn't have the manifold that would be an easy thing to retrofit.. It looks like Gardena no longer makes it but something like this would do the trick.. http://www.smarthome.com/claber-8581-4-way-garden-hose-distributor-valve.html?src=Froogle&gclid=Cj0KEQjwjrqvBRD6wf2fy-C61PIBEiQAUzKQTqBZo6oxmmCdI2986DJz5Ad57U5uQ_BWwlMV4-dN0lsaAspZ8P8HAQ On my boat the tanks are under the settees on either side of the cabin. They are clear plastic with a large inspection port on top.. It's pretty easy to remove the settee cushion / open the port and see exactly how much water is left. I can show pictures of my setup if you want.

My tanks are cross vented to one another through a low point loop. It appears that I could in theory fill all my tanks from one deck fill port despite having a fill port for each of my tanks. I'm thinking that tracking tank level is a challenge when they are all sluicing between one another. This doesn't seem advantageous. Why would the manufacturer do this. Is there a problem with me undoing it? Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
