I noticed that during system checking, I"ll use rubber plugs (ones that are shown on pumps) to clog sight glasses, they match perfectly.
I know, maybe someday I"ll upgrade it to keg.. since I couldn't ground it at plastic bucket I installed 0.03A FID switch in control panel. It should register any short circuit and brake power immediately.
