Answer: There isn't much that LIKES wet, clay soil, but there are shrubs more tolerant of those conditions than others. They include Redbud (Cercis canadensis), Japanese Snowball (Viburnum plicatum tomentosum), weigela and boxwood. If your faucet has a persistent drip or underground leak, nothing will last long there, so you'll need to have it repaired.
Have you considered installing a "hedge hydrant"? This product, sold by Gardener's Supply Co. (see http://www.gardeners.com/gardeners/-06-143.html/) lets you move your faucet outlet 10 feet from the wource. This would put it out of the range of the foundation plantings. Hope these ideas are helpful!
