Don't get pissed at us. Whether you're a total novice or old or whatever has nothing to do with your ability to post an accurate description of what you're trying to accomplish. You're original post asked if you could use a normally open valve. The answer was yes. (And there most certainly ARE 2-way normally open solenoid valves). And I had no idea what a water butt is-had to look it up.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 device I can clip on the bucket, an open valve which will close when water reaches the top of the bucket. Could someone just say if it is possible to make such a circuit?

How to read this, 9V battery is the only power supply? In this case, it's unlikely that any solenoid valve will have sufficient low power demand, either NO or NC type.I was assuming to use a 9v battery.
