Material for water level probes in fresh water tank.

Awesome! I had no idea there were such things as aftermarket probes. The OEM probes on my old tank look like they heated a piece of .25" x 1" metal and jambed it through the side of the tank then hit the perforation with a torch.

I will do some research on tank probes!

P.S. I have a total of 4 probes. 3 sensor probes and a single common probe. The single common probe is mounted higher than the lower sensor probe. Now there is some great engineering!
