Why are pump hoses in some trawlers apparently not installed with loops high
enough to prevent a siphon from starting? I cannot begin to think of a
reasonable excuse. So what if holes have to be cut in cabinetry or soles or
whatever - get the end of the loop up there!
My boat came to me sans check valves, sans siphon breaks in the two bilge
pumps, and I am not thinking of any changes. Their hoses run almost to the
main deck level before doubling back down to exit near the waterline. You
can flood the boat down three feet or heel it over at 30 degrees, and no
water is coming back through those bilge hoses. Sure, it raises the head
pressure a bit - so what? Get a bigger pump. Anybody ever had one too big?
Am I missing something here?
