Typically located in the lowest level of a home or building, sump pumps main function is to prevent flooding after a storm or heavy rainfall. If you own a home, or are purchasing a home with a basement, having the sump pump inspected, or installing one is crucial to preventing potential water issues. Sump pumps automatically monitor and pump out any water that may be building up in the pits of your home or business's foundation. A sump pump should be inspected once a year, normally after winter in preparation for upcoming spring storms. A few common signs that your sump pump needs to be replaced are: strange noises coming from your pump while it is running, constant running, visible rust or corrosion, irregular cycling, or is 7 years or older.
