Once a year, find your main valve. Turn it off. Turn it back on. This exercise keeps it from getting stuck. A valve that hasn’t moved in a decade? That is a ticking time bomb. You don’t want to discover it only when water is spraying everywhere. Trust me. I’ve seen the puddles.
Do the same for your toilet and sink valves. Give them a little wiggle. They’ll thank you. So will your future self, who doesn’t have to eat cereal out of a colander because the sink is flooded.
The Final Secret
If you ever have to turn the water off for a long time, open a lowest faucet (like in the basement). This drains the pipes and prevents frozen bursts in winter. Then open your highest faucet (like a second-floor bathroom). This lets air in. It’s like opening a wine bottle for your house. Classy.
And when the emergency is over? Turn the water back on slowly. A sudden gush of pressure can blow out a gasket. Let the air hiss out of the faucets for a minute. Listen to the pipes gurgle like a happy dragon. Then smile. You did it. You turned off the water. You’re now a master of the universe. Or at least of your own house.
Now, go find that valve. And maybe buy a backup valve wrench. You’re a pro now. Act like it.
