Main Water Line Replacement in Woodbridge, VA
A failing water service line is one of the few plumbing problems that costs you money every single day it goes unrepaired, because you are paying the utility for water that never reaches a fixture.
Older homes in the area may still have galvanized steel or early copper service lines. Both corrode and both eventually pinhole. Replacement in modern PEX or copper solves it permanently.
The main water line carries potable water from the meter at the street into your home. Failures show up as low pressure, a spiking water bill, or wet ground in the yard. Lud's Plumbing replaces main water lines in Woodbridge, VA, and this service qualifies for our written-quote price-match guarantee.
Signs you need main water line replacement
- Water pressure dropped noticeably across the whole house

- Water audible in the ground near the meter box
How we handle it
Step 1
Confirm the leak
We isolate the house side from the service side at the meter to prove the leak is in the buried line.
Step 2
Locate and mark
Utility locates are called and the run from meter to house is marked.
Step 3
Choose the method
Open trench or a pull-through replacement depending on what sits above the run — driveway, sidewalk, mature trees.
Step 4
Install new service
New line with proper burial depth below frost, a new main shut-off valve, and pressure testing before backfill.
Step 5
Inspect and restore
County inspection where required, compacted backfill, and restoration of the disturbed surface.

Main Water Line Replacement FAQs
How do I know if my main water line is leaking?
Shut off every fixture and appliance in the house, then watch the meter. If the dial or leak indicator still moves, water is escaping between the meter and the house. Wet ground along the run, falling pressure, and a rising bill with no usage change confirm it.
How long does main water line replacement take?
Most residential replacements are completed within one to two days once permitting and utility locates are done. Runs that cross a driveway or sidewalk, or that require deeper excavation, take longer. Water service is typically restored the same day the new line is installed and tested.
What material should a new water service line be?
Copper and PEX are both accepted for residential service. Copper is rigid and long-proven; PEX resists corrosion, tolerates ground movement, and can often be pulled through with less excavation. We recommend based on soil conditions, run length, and what sits above the path.
Will the yard be destroyed?
Not necessarily. Where conditions allow, a pull-through replacement needs only a pit at each end rather than a full-length trench. Where open trenching is required, we compact the backfill and restore the surface, though grass regrowth and hardscape repair may be scheduled separately.
Is low water pressure always the main line?
No. Low pressure across the entire house points to the service line, the main shut-off, or a failing pressure-reducing valve. Low pressure at one fixture is almost always an aerator, a supply stop, or a cartridge. We test at the hose bib nearest the meter to identify which category you are in.
