Overview
Replacing the line that runs under your yard
The main line between the meter and the house is out of sight for decades, which is why it usually gets attention only when it fails. By then the pipe may have been leaking slowly for a while, or it may have reached the point where one repair is followed by another.
An underground replacement swaps the entire buried run for new pipe. The job is shaped by what sits on top of the line: lawn and planting beds are straightforward, while driveways, patios and retaining walls change the plan. We walk the route with you first so you know where we will dig and what will be disturbed.

What's included
What our underground water line replacement covers
Route planning
We confirm where the existing line runs and decide whether to follow it or take a better path.
Hardscape planning
Driveways, walkways and patios are mapped so we disturb as little as possible.
Excavation
The trench is dug to the depth the new line needs along the full run.
New pipe installation
We lay new copper or PEX with fittings suited to buried service.
Connections at both ends
The new line is tied in at the meter side and where it enters the house.
Testing and backfill
The line is pressure tested, then the trench is backfilled and compacted.

Warning signs
Signs the buried line is worn out
Repeated leaks
More than one leak in a few years usually means the whole run is deteriorating.
Old galvanized or unknown pipe
Older buried steel lines corrode from inside and out and tend to fail in sequence.
Weak pressure that keeps fading
Gradually falling pressure can mean buildup or damage along the whole line.
Discolored water at every tap
Rust-colored water across the house can come from an aging main line.
Soggy soil that comes back
Wet patches that return after a repair suggest more than one weak spot.
Shifting soil or settling
Hillside and clay soils can stress older lines until they crack in several places.
When to call
When to plan a replacement
If you have repaired the main line before and now have another leak, it is worth asking whether replacement makes more sense than a second patch. The same goes for older homes where the line is the original pipe and has never been replaced.
Planning a replacement on your own schedule is easier than doing it during a failure. Calling before the line bursts lets you choose timing that works around your household.

Underground Water Line Replacement questions
Will you have to tear up my driveway?
Not always. Where we can, we route the new line around concrete instead of under it. If the line has to cross hardscape, we explain the options before we start.
How long will I be without water?
Only while we disconnect the old line and connect the new one at each end. We tell you before the water goes off and roughly how long it will stay off.
What pipe do you use for the new line?
We typically use copper or PEX, chosen for the soil, the run and how the line connects at each end.
Does the replacement need a permit?
Main line replacements generally require a permit and inspection. We explain what your city or county requires before work begins.
Can you reuse the old trench?
Sometimes. Following the old route can be simplest, but if it runs under a slab or tree, a new route is usually better.
