First thing I do is disconnect the damn things. I've had a lot more dead batteries due to them than I have boats saved because of them.

And I thought I was the only one with this problem! I keep my boat on a Hydro-Hoist but water collects in the bilge after a hard rain. A couple of years ago, the pump came on after a lot of rain and ran the batteries down. Over that winter I hit the pivot with spray Gunk. The pump still works (It's a Rule). Since that time I take no chances on the hoist while I'm gone. I've got a stick that I slide down between the headers that rests on the flapper valve. I've never forgotten to remove it since I'm always checking stuff back there before I go out. Replacing the switch in my boat would be a nightmare. I always check the pump to make sure it's working before I go out. The pivot hasn't stuck since.

TTT for one more pass.

Another picture of the bad float switch.

My switches are allso Attwoods. They are either always hanging on, not working or coming apart.

Connect the auto float hot wire direct to battery.

Connect other hot wire to a switch.

Either way you are fine.

Exactly Tommy,
AT and Sonic rig the Auto Bilge function to a switch.

Those Rule automatic pumps Milord listed switch on every 2.5 minutes, looking for water, and cost a ton.

The Water Witch was the first solid-state switch I ever saw, and came out about 10 years ago. There's a new on out called SensaSwitch that's smaller, completely sealed, reasonably priced, and has no exposed sensors. Costs $25 for small pumps (up 12 amps): SensaSwitch . I'm putting one in the boat I'm re-rigging now.

In the meantime, I checked the Rule (not Attwood) switches in my Formula. They're vented, but can get gummed up by the usual bilge gunk. A good shot with a garden hose around the base of the switch, and through the vent hole sorts that right out...

By the way, is anyone looking for a 1250 gph Atwood pump? I just pulled one of this re-rig job. It's in good shape, but since I can't get to it with the engine in the boat, I figured this was a good time to change it out. It's only got 170 hours on it.
