Many homes, mostly in rural settings, depend on wells to supply their water. When you buy a home that has a well, you should understand that there are certain things you need to learn about that other homeowners don't have to be concerned with. One example is being able to recognize when your well may be running dry.
Turn on your faucet. If your home uses well water and the well is running dry, then your faucets will sputter when your turn them on or air may come out in addition to or instead of water.
Examine the water that does come out of your faucets. When your well is running dry, the water may appear darker in color or look muddy.
Taste the water that comes out of your faucet. If your well is running dry, the water may taste different than it normally tastes.
Hire a water-well professional to measure the level of the water to determine whether the water in the well is running dry or whether there's some other problem with the well or its equipment.
