The last time I had my pup out was the NC Spring Rally (a month ago). I opened the cold and hot water drain lines for the ride home and all was well. It has, without exaggeration, rained every day since then here in the NC mountains. We finally have some nice weather today, so I headed out to see how the pup was doing. It's been hot today, so no water on the ground or anything - the driveway is dry. I noticed a strange puddle under the pup. I crawled underneath and immediately felt all the floor boards - ship shape. Then I noticed a drip coming from the cold water drain line - it's dripping water. The valve is open and has been for a month, so I sincerely doubt there's any water left in the system from a month ago. Any ideas?
