Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

    A GFCI is designed to trip when it recognizes that some the electricity leaving the receptacle is not returning back, and someone could be getting shocked or even electrocuted because of it. All receptacles in wet locations such as kitchens, bathrooms, garage, and exterior are required to be GFCI-protected. Because the first receptacle in a string of them running around the home will protect all the ones downstream if it is a GFCI, builders put a GFCI-receptacle in one bathroom, for example, and it protects receptacles in other bathrooms around the house that do not have the push-buttons. Sometimes a GFCI-receptacle in the garage will protect all the bathrooms in a home. So go around your home looking for GFCI-receptacles to see if the top button is popped out. If so, then push it in to reset the GFCI-device and open the circuit and you may—possibly, just possibly—have solved your dead bathroom receptacle mystery.

    To learn more about GFCI-receptacles, go to our blog post Why does that wall plug have push-buttons in the middle?”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
