Anyone know why does the Rule Eco Bilge comes in 12V and 24V versions?

I assumed it was a purely mechanical device.

It needs a negative feed, as well as a positive feed, so presumably it has some electronics in it, or a simple relay.

On reflection I guess a microswitch is not really going to like switching 20A so a relay seems likely.

I have a very old version and some people doing work on the boat messed around with the wiring. Now it seems to be permanently on without the negative even being connected which I find hard to understand - relays would hardly ever fail "on" in such applications.

I suspect it is dead but I suppose I can take it apart to find out before replacing it - the trouble is it leaves the boat without an automatic pump at the moment and I am nervous about that

Sounds like it might have failed, although maybe the wiring is just the problem. Your boat should be fine; I've never had an automatic bilge pump in 40+ years of boating. If there's a serious leak, the average bilge pump wouldn't cope anyway.

If it needs changing, these work well ; https://www.asap-supplies.com/whale-bilge-electronic-field-sensor-504859
