I may be retarded or just mentally incapable of explaining what I want to google so bear with me for a second.
I got a line of trapdoors holding back water and I want to send a redstone signal so they can open and close, I can't connect dust or repeaters directly to the block holding the trapdoors because the water will wash away the redstone, so I make a line of redstone for the signal and then I have to have a line of repeaters pushing the signal into cobblestone that keeps the line safe and dry. Pic related is the way I figured I could extend the lines without breaking the signal.
Was there a better / easier / less repeater-bleeding way of doing this?
