Main Water Line Repair in Marietta, GA
When the problem isn't one fixture but the whole house — no water, or barely any — the main service line between the meter and the home is usually the cause. Here's how main water line repair works.
Why Main Line Problems Feel Different
The main water line, also called the service line, runs from your meter to your home — the single point every fixture and appliance draws from. Because it feeds the entire house, a failure there rarely stays isolated to one room: low pressure at every fixture, a sudden drop to little or no water, or the meter still registering flow with everything off.
Compare this against symptoms confined to a single sink or bathroom, which usually point to interior plumbing instead. For a broader look at underground water-line issues in general, see underground water line repair.
Main Line Diagnosis
A meter test, visual inspection of the yard and meter box, and acoustic listening equipment help confirm and locate the issue before digging.
Spot Repair
Locate the line, confirm the failure point, excavate only the area needed, repair the pipe, then backfill and restore the surface.
Common Failure Causes
Age and material, corrosion, ground movement, and physical damage from nearby digging are the usual causes of main line failure.
Repair vs. Replacement Assessment
A spot repair often makes sense when the rest of the line is sound; repeated failures or old galvanized material point toward replacement instead.
Whole-House Pressure Loss
Low pressure at every fixture, a sudden loss of water, a meter that keeps moving, or a wet area between the meter and the house.
Permits for Main Line Work
Work on the service line requires a plumbing permit in the City of Marietta, applied for by a licensed professional on your behalf.

Every main line repair is scoped individually, but the same handful of factors tend to drive how much work is actually involved.

Main Water Line Repair FAQ
Common questions about main line problems and repair in Marietta.
How is a main water line problem different from a single leaky pipe inside my house?
An interior leak — a supply line under a sink, a toilet fill valve — usually affects one fixture and is accessible without digging. The main line feeds the entire house, so a problem there tends to show up as whole-house symptoms: low pressure everywhere, no water at all, or a meter that keeps registering flow with every fixture off.
Can a main line problem be fixed without digging up the whole yard?
Often, yes. If the line can be located and the failure is isolated to one section, a targeted excavation at that spot is usually enough. See our overview of underground water line repair for how spot repairs generally work.
How urgent is a main line repair?
It depends on the symptom. A slow pressure decline over weeks is worth scheduling soon but isn't necessarily an emergency. A sudden total loss of water, or water surfacing in the yard, is more urgent — see broken underground pipe repair for what to do first.
Will a main line repair also fix my low pressure at just one faucet?
Not necessarily. Pressure trouble at a single fixture is more often a fixture, aerator, or interior-plumbing issue rather than the main line. Whole-house pressure loss is the stronger signal that the main line itself is involved.
What affects the cost of a main line repair?
The line's length and depth, how easy the break is to reach, the pipe material, and whether the fix is a small spot excavation or something more involved all factor in. We don't quote pricing without seeing the property and locating the problem first.
Does a main line repair require shutting off water to the whole house?
Usually, at least for part of the work. Because the main line is the single supply point for the house, water typically needs to be off at the meter while the repair is made, then restored once the line is reconnected and tested.
