A dripping faucet or running toilet can waste hundreds of gallons of water a month and quietly inflate your bill. The good news is that most household leaks come from worn washers, loose connections, or aging seals — all cheap and easy to replace. In this post we walk through how to spot a leak early, the basic tools you’ll want on hand (an adjustable wrench, plumber’s tape, and a bucket), and step-by-step fixes for the five most common culprits. If a repair turns into standing water or pipe corrosion, that’s your cue to call a pro before it becomes a bigger problem.
