Broken Main Water Line Repair
The main water line runs underground from the street to your home, and a break can waste enormous amounts of water while leaving you with little pressure. Common causes include freezing, shifting soil, tree roots, and aging pipe. FlowFast connects you with an independent local plumber who can locate the break and repair the damaged section.

Emergency PlumbingBurst pipe or major leak right now? What counts as a plumbing emergency, what to do before the pro arrives, and how to get connected with an independent local plumber fast.
View all Emergency servicesYour main water line is the one pipe your entire home depends on, and it lives out of sight underground — which means breaks often go unnoticed until the symptoms get dramatic. A soggy patch in the yard that never dries, water bubbling up through the lawn, a sudden collapse in water pressure, or a shocking water bill can all point to a break between the street and your house. Because the leak is underground, thousands of gallons can escape before anyone connects the dots.
FlowFast connects you with an independent local plumber who can pinpoint the break using listening equipment or line-tracing tools, then excavate precisely at the problem spot rather than digging up your whole yard. Depending on the pipe's condition, the pro will repair the broken section or recommend replacing the full run if the line is old and failing in multiple places. They will also restore water pressure and test the line before backfilling. The sooner the pro is on site, the simpler and less disruptive the repair tends to be.
Warning signs
Signs you need this service
- An area of the yard that stays soggy or muddy even in dry weather, sometimes with water visibly bubbling to the surface.
- A sudden, severe drop in water pressure throughout the whole house, not just at one faucet. Which makes a professional diagnosis worthwhile.
- A water bill that spikes dramatically with no change in your household's actual water use. So do not wait to get it checked.
- The sound of running water when everything is off, or a water meter that spins with no taps running. Before it gets worse.
What to expect
The process, step by step
The pro traces the underground line and pinpoints the break so excavation stays as small and targeted as possible. Ensuring the problem is fully resolved.
The area is dug out to expose the pipe, and the broken section is cut away for inspection of the surrounding line.
New pipe is installed to match the existing line, with proper fittings, bedding, and depth for your region. Which keeps the work neat and contained.
The line is pressure-tested, the trench is backfilled and compacted, and water service is restored and verified. Keeping you informed at every stage.
Prevention
How to avoid this problem
- Know where your line runs and avoid planting deep-rooted trees or driving heavy equipment over it. So stay consistent.
- In freezing climates, make sure the line is buried below the frost line, which a pro can verify during other work.
- If your service line is old galvanized or polybutylene pipe, plan a proactive replacement before it fails underground.
