leak

Had a water leak. I found it because I saw the dogs had muddy feet and there shouldn't have been any mud. It looked easy to dig out so I started Wednesday evening and of course it wasn't so I turned the water back on so the horses could have a drink. Thursday morning I got out early because I didn't want the horses without water for long. Siete came over to get a drink.When nothing came she hit it with her foot and tried again. I was about 20 feet away, outside the pen in the hole and she looked at me. She was telling me dad, the water's off. I couldn't turn it back on so she stood perfectly still with the waterer between her front legs and raised her head up high and stared at sky. I knew she was watching me since horses see very well to the side. When I turned it on the was there for her drink. This waterer doesn't make noise when there's water so I don't know how she knew it was on.
