SNIP>>>If you want a really dry bilge you'll have to install a
positive-displacement pump. ... Use an adjustable diaphragm switch mounted
high
and a piece of clear vinyl tube to reach to the bottom of the bilge. The best
of these will have an adjustment that will allow on and off settings in the
1-4" range. John "Seahorse"
John, can you give us examples of "positive-displacement pumps?"
I find this an interesting thread as I installed PSS shaft seals thinking it
would lead to a dry bilge but water comes in from too many other sources so
now my objective is to pump as much of the water out as I can.
