Average Reviews:
(More customer reviews)The idea of this switch is to allow the bilge pump to come on automatically when the water level in the bilge gets to a certain level (1 or 2 inches approx) and then stay on until the floating actuator drops back down as the water in the bilge falls below that level. The problem with this switch is that it won't shut off when it should. Every time it has come on, it has failed to shut off when it should. It continues to run, pumping air instead of water, as it was intended to do. The way it was manufactured there just isn't enough floating weight in it to drop back down and shut off when the pump starts pumping air instead of water.As a result, it continues to run until either you hear it still running, or your battery runs down whichever occurs first! (fortunately attwood bilge pumps draw so little juice, it runs forever on a fully charged 12v batter ). If wired directly to the battery as the instructions say to do, the only way to shut it off is to reach down into the bilge and pull up on the switch, or disconnect the battery cable or the bilge pump wire from the battery. (unless you wire it to a on/off dashboard switch).
Some might say I didn't follow the instructions when I installed it - but I did, to the letter.
Using a little "mickey mouse" technology however, I was able to get it to work by attaching about a 1/2oz fishing weight (I glued it on the top of the switch using a waterproof marine sealer). Now it works fine.
It makes me wonder how something like this can get to the market when so much depends on this little device. Apparently Attwood doesn't check these in real life situations, which to me, is a little scary.
