Thanks for all replies. I have the 12v solenoid valve, my only problem was to make it close on a signal. And the answer turned out to be very simple, use a 12v normally closed relay.
It was a perfectly accurate description of what I'm trying to do - and you're (or as most of us would say 'your') answer was "that's not possible" which I take as a no. I was seeking electronics advice rather than lifestyle advice, which I seem now to have found, and would appreciate no further...
This isn't getting far. A bucket takes time to fill, I'm old and a tital novice to electronics (which is mainly why this is so difficult for me and why 'why would you want...' questions don't help) I wander off and do something else and come back to a flood and a wasted water butt. I imagine a...
You'd think, but when the water level reaches the wires it makes rather than breaks the circuit. If I have to stand there and switch off the solenoid I might as well switch off the water butt :-)
Is it possible to use a 'normally closed' 12v valve so that it is normally open and closes when water level reaches the sensors? I can't find a 'normally open' one anywhere. (Yes total beginner, please reply in words of ½ a syllable. I want to make a device to switch off the supply from the...
