I recentlt replaced a leaky hot water heater drain valve with a nice brass one. However I notice that some of the insulation stays wet around it when I feel back the rubber grommet. I notice even tiny droplets of water on the outside of the metal jacket under the grommet. There doesn't appear to be a leak where valve connects as I can look and see no leak. Also if it leaked it would leak down and the insulation on the sides wouldn't be wet. What's the cause of this? It wasn't wet before I replaced the drain valve. I'm pretty sure because I did this as one of my checls. My drain valve had been leaking where the water actually drains from and at the handle.
