I'm adding an electrical line to my outdoor pool breaker box. I was digging near the box with a pickaxe (yeah, I know, stupid) and was trying to be careful, but I was not careful enough. I don't believe the wire cable itself is damaged, but it is possible. The conduit and its hole is shown below. Unfortunately some mud has gotten into the hole because of the rain last night.
Some water leaked out of the conduit when I made the hole so water was already getting in. Given that, I'm inclined to either leave it as-is or wrap it with duct tape or something. I could cut it and splice it inside of an outdoor electrical box but I'm not sure if it's worth the trouble or not. Advice would be appreciated.
