The main water supply source is typically in the basement or near a lower exterior wall. It branches into pipes that run through walls, ceilings, and floors, serving every plumbing fixture, faucet, and appliance. Pipes are essentially everywhere, branching into numerous sections.
If you couldn't find your meter, look for the service line by checking your basement or first floor, looking first along the exterior walls particularly on the side of the building facing the street. The incoming pipe will come through an external wall or the floor and then connect to the water meter.
The pipes that power faucets, showers, toilets, and other fixtures are typically hidden behind walls or under floors, a setup that requires careful planning for proper installation.
Your local water company will provide you with clean, drinkable water, remove waste water and sewage. From their main supply pipe, under the road outside your home, a branch pipe will run underground to a stop valve beneath a metal plate, which is set in the pavement or somewhere in your front garden.
This supply line is buried deep enough underneath your property that it won't freeze, and it runs from the ground directly into the home. Supply lines are usually made of plastic, galvanized iron, or (ideally) copper.
Pipes in attics, crawl spaces and outside walls are all vulnerable to freezing, especially if there are cracks or openings that allow cold, outside air to flow across the pipes.

One misconception we'd like to clear up first, though, is there are no pipes IN the concrete slab. And this means there can't be a leak within the foundation. In most cases, the pipes are under the slab. So you if you do have a leak, it is under the foundation.
Stud finders equipped with AC detection are indispensable tools for homeowners keen on pinpointing the exact locations of plumbing lines in their walls. The AC detection capability enhances the tool's ability to sense nearby electrical currents, which often run parallel to plumbing routes.
You'll want to find where the service line enters your home—typically in the basement or crawl space, just prior to the shutoff valve. The water meter may be in the same location, but in some areas, the water meters are outside the home.
After shutting off the main valve, ensure you drain the water from all the fixtures. In summer, the temperature of the water raises the pressure inside the pipes. If there is a crack, parts of your plumbing could burst. It is even more critical to drain hoses and faucets in the winter.
The main water line may be behind drywall, paneling, the ceiling, or flooring. Follow visible water lines near the water heater.
Sand or gravel areas in the bottom of valleys will often be home to groundwater. These layers can be covered by clay or silt, so it's prudent to check these areas thoroughly. Natural springs usually indicate groundwater is nearby. A spring that flows year-round will likely reveal a productive aquifer.
It comes straight into your house from the water mains. The water from this tap is usually moving and flowing and has not been stagnant (still or stationary).
In general, plumbing lines run either down from above or up from below to supply fixtures and appliances. There are exceptions, such as multiple fixtures in close proximity on the same wall and restrictive floor plan layout. In some scenarios, the plumbing lines may be run horizontally through the wall framing.
Homeowners insurance typically covers losses resulting from a sudden malfunction, such as a pipe bursting unexpectedly. However, a homeowners policy won't cover slow, constant leaks or other plumbing problems resulting from neglect or improper maintenance.
Start with a visual inspection
Begin by looking in the most obvious places: under sinks, in the basement, or utility areas where pipes are often exposed. Follow these pipes as far as you can to get a general idea of the direction they're heading.
The main water pipes are installed underneath this foundation, and the house is built on top of it. A slab leak occurs when a water pipe leaks under a concrete slab foundation. Since the water lines are beneath the house, you may not even realize that you have a major plumbing issue developing.
Blueprints and Plumbing Diagrams
Homeowners can often find these in a property's original building plans or request them from the local building department. Online resources and home improvement sites like It Is House also provide information on accessing or creating a plumbing diagram.
Accidental water damage that occurs as a result of a sudden, unexpected occurrence like a burst pipe is often covered by a homeowners insurance policy. In addition, cleaning, repair or replacement of wood flooring, drywall and even furniture due to water damage as a result of a burst pipe typically is covered.
One of the earliest signs of breaks or leaks is unusual noise. Strange noises like trickling, gurgling, or hissing can hint at a leak. The volume of the sound typically indicates the severity of the problem, but not always. Volume can also increase or decrease depending on the diameter of the affected pipe.
