Virtually all major appliances connect to something. At the very least, major appliances connect to electricity, often requiring a 220v line. A hot water heater must connect to a water supply and either electricity or a gas line. A stove or range must connect to either electricity or a gas line, or both. The refrigerator must have electricity and, today, a water supply for the icemaker or supply of cold water. The washer must have both power and water supply, and the dryer requires both power and a vent. Moving these connections and power sources can become very expensive, not only in terms of the labor costs, but because of the additional tearing out of existing walls, floors, etc. to make the changes. When you add together the damage and repairs and the labor and parts charges, the amount can be fairly high. Once again, attention to these seemingly small details can save money on your remodeling project by reducing the amount of work required.
