I'm a bit confused. When pumping overboard, the sound of he macerator will change dramatically when the tank is empty.My frustration is with not knowing how full the tank is so when trying to empty it out at sea without burning up the macerator, I am never sure. Stupid system.
I am going to find some kind of dye to put in it so I can always know.
But, how will a dye help you know the level in the tank?
