How do I find my main water shutoff valve in an emergency?
New homeowners often forget to locate their main water valve after moving in, leaving them scrambling with a flashlight during a sudden leak. Sticking or rusted valves cause further panic when they won't budge, leaving people afraid to force them and risk breaking the pipe while waiting days for a plumber.
