Seriously—write it down. Grab a piece of duct tape and a sharpie, and label the valve “WATER OFF” with an arrow. Tape it right next to the valve or on the pipe above it. You’ll thank yourself at 2 a.m. when your brain is foggy.
Show your family, your roommate, or even your pet (okay, maybe not the pet, but tell them anyway). Make it a household game: “Who can find the water shut-off in under 30 seconds?” Winner gets extra dessert. Everyone wins because no one floods.
