Check the Meter
If you suspect a leak, monitoring your home’s water meter will give you a definitive answer.
The meter is often located beneath a manhole-type cover near the street or (in areas where temperatures don’t dip below freezing) on the side or back of the house, near to where the water supply line enters the house.
If the water meter test indicates a leak inside your home, check the cabinets under the kitchen, laundry, and bathroom sinks to make sure they’re dry. You’ll also want to look for puddles around the bases of tubs, toilets, and showers and beneath the water heater, dishwasher, and clothes washer. If you find any puddles, turn off the water supply valve to that appliance or fixture and call a plumber.
