A delayed reaction float doesn’t necessarily guarantee a dry bilge. That depends on the pump’s ability to remove all the water before it sucks air, which is impossible. Then you have issue of the water in the hose falling back into the bilge after the pump stops, which is certainly negligible. But if the switch were to not shut off the pump could possibly fail or at best continue running dry. I’ve seen that with the electronic float switch which doesn’t actually have a float but senses the water electronically. It all depends on the level of the float and pump. So I wouldn’t agonize over expecting to have a totally dry bilge. But I do think that switch looks like a nice value. It’s interesting that the big marine manufacturers continue to sell their products at exorbitant prices on the premise that they are somehow “specially made” for the purpose. And if you look you may find that in many cases their products also come from China. Nice review.
