The Bates family will never forget their house fire, and so they organize a car-washing fundraiser to give back to the heroic volunteer firefighters who responded to their emergency situation. Right before the big day, Zach insists on giving the Bates kids a tutorial on the do's and don'ts of properly washing a car. But will a family water fight put an end to Zach's lesson? Meanwhile, Chad and Erin are interested in purchasing a "fixer upper" house and begin the search for a property that they hope to renovate and call their own!
