Standing water under a house is usually the result of only two things; either a leaking water line, or from surface water drainage around the house. If it was from a leaking water line, the leak would have to be substantial, and you would hear running water in the house.
Rainwater that drains under your house can flood your basement or lowest housing level and cause mold to grow. The damp conditions can even bring termites into the house, causing further damage to its structure. Fortunately, stopping rainwater from draining under your house is a fairly simple process. It may even lower your water bill by allowing you to use captured or diverted rainwater to irrigate the lawn, flowers and other ornamental plants in your yard. Ensure the soil is graded to slope away from the house.
