How do I know if my main water line is leaking?

Signs of a main water line leak include a sudden drop in water pressure, an unexplained increase in your water bill, a wet or soggy area in your yard (especially in a line from the house to the street), the sound of running water when nothing is on, and mud or sinkholes in the yard. Check your water meter — if it's moving with everything off, you likely have a leak.

What material is my main water line made of?

Depending on when your home was built, it could be copper, galvanized steel, lead (pre-1950s homes), polybutylene (1970s-1990s), or PEX. Galvanized and lead lines should be replaced. We can identify your pipe material during an inspection and recommend whether replacement is warranted based on the material's condition and age.

Am I responsible for the water line from the street to my house?

In most Illinois municipalities, the homeowner is responsible for the water service line from the meter pit or curb stop to the house. The municipality maintains the main in the street. Some villages have programs to help with the cost of water line replacement. Check with your local village for their specific policies.

Can the water line be replaced without digging up my entire yard?

In many cases, yes. Trenchless methods like pipe pulling or directional boring can replace the water line with only two small excavation points. This preserves your driveway, sidewalk, and landscaping. The feasibility depends on the pipe route, depth, and any obstacles. We evaluate whether trenchless is an option during our assessment.

What causes low water pressure throughout my whole house?

Whole-house low pressure is usually caused by a problem with the main water line — a partially closed valve, a leak, a corroded or restricted pipe, or a failing pressure regulator. Municipal supply issues can also be a factor. We test pressure at the meter and at the house to isolate where the pressure drop is occurring.

How long does a main water line replacement take?

Most residential water line replacements are completed in one day. Trenchless replacements are often faster. The timeline depends on the length of the line, depth, soil conditions, and whether excavation through driveways or sidewalks is needed. We restore water service by the end of the work day.
