Will this float switch idea work?
I wanted to install a float switch in said barrel to turn off the pump when the barrel is full, but was trying to avoid having to run wire all the way from the pump/controller/battery set-up at the stream to the barrel.
I had this idea that if I pumped water first into a 5-gal bucket mounted on a tree near the pump and raised it up above the barrel, Not only would I make the most of my pump's feeble lift (by reducing the friction it must overcome and allowing gravity to do the work), but it would also allow me to put a float switch on the bucket itself, rather than in the barrel, thus reducing the wire run significantly.
Here's a picture (not all system components represented). Will it work? I'm wondering if there's a physical/practical consideration that I'm missing...
Thanks for having a look!
