Quote: A load sensing pump will be started up dry every few minutes unitl the seal burns out through running dry. Then when you need the pump it will fail quickly.
Exactly. That's exactly why I disregard load-sensing pumps as an option. The Quick BS I really like, because it's damn near indestructible and hasn't got any moving parts to fail. RuleMate pumps have a built-in switch and need water to close the circuit, so the pump doesn't run dry for very long at all, and when the level's down, they switch off. No electronics to fail or give jip! I do think an auto pump's a must if you're going to leave your boat afloat or if you've got any way for water to make ingress- stern-glands, skinfittings, etc, and fitting an alarm, especially if there are unserviced compartments, makes belt-and-braces sense. Engine compartments and in thru-hull compartments are obvious places.
