I'm looking for recommendations for a self-priming diaphragm pump
that has a 3/4 inch hose connections. I need two of them. One for the bilge pump
and one for the sump pump
. Would like the pumps to be the same for both bilge
and sump, so they can be interchanged in a pinch. Also my bilge pump
is plumbed below waterline so it needs somehow support anti-siphoning. Also needs to be able to pump at least 25 feet or so, since bilge/sump are a long way from the thru-hull fitting.
