I'm making a water detector. This will be used to monitor water in my sump pump discharge pipe, so it will be seeing water every 10 minutes or so. I need something stiff that I can insert into a threaded cap that I will be attaching to a "T" on my PVC piping.
My first thought was to use 14g copper ground wire from some romex I have. Its stiff enough. But then read that copper oxides in the presence of moisture. Would this oxidization prohibit the conductivity?
I also thought about using aluminum, I went to the hardware store and they have aluminum rod but its not thin enough, I would like something no larger than 12g in diameter, although 10g might work too.
I think I can get small brass rod at the hobby store, I've seen it there before but wasn't really looking closely. They might have aluminum too.
Any suggestions?
