Intermittent Bilge

I'll take a look for a stock float switch. That could be it. I did not install the automatics. I'm just going to get rid of them. If there is not a correct craft automatic switch I'll put in a Rule brand one that goes with the rule pumps.
Thanks

Are you the original owner? Did you put the Rule pumps in? If no I'd check and see if there is a Correct Craft installed switch that may be conflicting with the ones in the pump then. My switch is mounted by the back pump just in front of the rudder but is wired to control both pumps

It sounds like you have two of these:

Rule 500 Automatic

They are supposed to cycle on every 2 1/2 minutes and stay on if the pump senses a load on the impeller, that is how the automatic function works. I am guessing that the electronics sense the amp draw to determine if water is there. They sometimes act funky like you are describing when they get older. I am personally not a fan of this type of automatic pump as they tend to wear out faster than others due to the automatic cycling, not to mention they run the battery down for no reason when there is no water in the bilge. I used to run a big motoryacht with these pumps in several "nuisance water" areas, and found they usually lasted about a year under constant duty. Folks usually install them for ease of wiring or tight space constraints. I suggest changing out for a standard pump with floatswitch.

I'll start off by saying, "Yes I did search through old topics to see if I could find an answer". I have two Rule 500 GPH bilge pumps which are "computer controlled" what ever that means and is likely the root of the problem. The pumps seem to come on and off at random times.
Scenario: Boat has a bunch of water in it and the Bilge power was not on while not in use. (I don't like to rain the battery and the boat is behind my house int eh water so if there is a bunch of rain I can turn them on
I turn on the bilge power. Nothing happens. Then after a couple of minutes (or maybe not at all) one pump will just start going. Then it will stop a few minutes later. 15 minutes later one of the two will come on again and then go off again after a few minutes. They stop before the boat bilge water is below pump level. No, I don't have a leak. I can open the engine cover to see they are still working on the same collected water but strangely taking breaks while they work, or don't work. Took out screens they are not clogged.
So crappy pumps or is there something else going on that might be indicative that they are both doing it at the same time.
Thanks
