Yard service line leak
A wet strip, a soft spot, or a bill climb with no indoor leak — the buried line losing water to the soil.
Water Line Repair & Installation — Triangle, VA 22172
The water line is the pipe that brings Prince William Water's supply from the meter to your house — plus the main runs inside that everything else branches from. When it leaks, pressure sags, or age catches up with it, every fixture in the home feels it. This page covers finding, repairing, and replacing those supply lines.
24/7 line for urgent problems. Scheduled visits for everything else — honestly sorted on the first call.
Two clues point at the water line before anything is dug: pressure that fell across the whole house, and ground that stays wet along the line's path during a dry spell. A third clue is arithmetic — a meter that moves with the house valve closed means water is leaving between the meter and that valve.
Call (855) 913-0016 and describe which pattern you have. If the yard is actively pooling or the meter is spinning fast, treat it as urgent and close the meter-side or house valve to stop the loss while we plan the locate. A slow pressure decline over months is a scheduled diagnosis — but schedule it, because lines do not heal.
A wet strip, a soft spot, or a bill climb with no indoor leak — the buried line losing water to the soil.
A partly failed line, a clogged or tired regulator, or scale narrowing an old galvanized service.
Rust narrowing the pipe from inside until flow at showers and laundry cannot keep up.
Older plastic service pipe with a known failure history, often replaced proactively or at first leak.
Fittings at the meter or the house entry weeping where materials change and soil moves.
A shallow-buried stretch that froze in a hard snap, splitting where cover was thinnest.
The first heavy run inside the house — often in a crawl space — thinning and pinholing with age.
The pattern that says the line's material, not the spot, is the problem.
Water line work joins two trades: detection to find the failure, and careful excavation or interior work to fix it at the right scope.

Supply problems feel different from drain problems: everything weakens together. Match your pattern here.
| Symptom | Likely cause | Urgency | Next step |
|---|---|---|---|
| Every fixture lost pressure over months | Scale or corrosion narrowing the service line | Scheduled diagnosis — worsening trend | Book a pressure test |
| Wet yard strip in dry weather | Service line leaking underground | Urgent — continuous water loss | Close house valve test; call today |
| Meter moves with house valve closed | Leak between meter and house valve | Urgent — that section is yours to fix | Call for locating this week |
| Pressure fine at one hose bib, weak indoors | Interior restriction or regulator issue | Routine — pinpoint by testing | Book an interior check |
| Discolored water after every quiet period | Corroding galvanized line shedding rust | This month — line condition question | Ask about material assessment |
Age and material write most of the story. Galvanized steel services from the area's earlier building decades rust from inside; some plastic lines from later decades carry their own failure reputations. Either way, the line that was adequate for forty years narrows, thins, and finally weeps at its weakest joint or bend.
Soil writes the rest. Clay ground near Quantico Creek and Chopawamsic Creek swells and shrinks with the seasons, flexing buried lines at their fittings. Tree roots do not drink from pressurized lines the way they invade sewers, but root growth and settling shift soil around the pipe. Add a freeze where cover is shallow and a line gets tested from three directions in one year.
The boundary tests come first: meter behavior with the house valve open versus closed splits the world into 'street side of the valve' and 'house side.' Static and flowing pressure readings at an outside bib then show whether the problem is volume, pressure, or both.
For a buried leak, acoustic listening along the located path and soil probing at the wettest point converge on the dig spot. We mark depth as well as position, because a line under a driveway or a mature planting deserves one accurate excavation — and we confirm the pipe's material at the first opening, since material decides whether a spot repair or a replacement conversation follows.

A spot repair replaces the failed joint or short section and pressure-tests the line — the right scope when the exposed pipe on both sides is clean, full-sized, and sound. We show you that exposed pipe; its condition is the argument.
Full replacement pulls or bores a new service line — commonly modern polyethylene or copper as conditions and code practice dictate — from meter to house entry, with a new shutoff and, where pressure warrants, a regulator. Where routing allows, trenchless pulling reduces the yard damage to access pits at each end. Either method ends with the same proofs: pressure held, meter still, fixtures flushed clear.
One exposed section usually answers this question by itself. Here is how we read it.
| Situation | Recommended path | Why |
|---|---|---|
| Isolated joint failure; pipe clean and full-bore both sides | Spot repair | The line has years left; the joint did not |
| Widespread internal rust or narrowing | Full replacement | Every future repair inherits the same narrowing |
| Problem-era plastic with any failure | Full replacement | The material's history argues against spot trust |
| Second leak within a few years | Full replacement | The pattern has already voted |
A service line break that floods a yard, undermines a driveway edge, or spins the meter is tonight's work: close the meter-side valve if you can do so safely, or the house valve, and call (855) 913-0016. Water escaping under pressure underground can erode soil voids that surfaces later collapse into, so speed genuinely matters beyond the water bill.
A home with no water at all also counts: we will help you determine on the phone whether the cause is your line, your valve, or a Prince William Water outage affecting the street.
Eastern Prince William County — Triangle included — receives water sourced from the Occoquan Reservoir, treated at Fairfax Water's Frederick P. Griffith Water Treatment Plant, and distributed by Prince William Water, the county authority formerly known as the Prince William County Service Authority. That water is moderately hard, which matters inside the house for scale, but for the buried line the bigger local facts are soil and age.
Streets around Graham Park and Old Triangle Road hold the oldest services, many now in the window where galvanized narrowing shows up as weak showers. Newer builds near Potomac Highlands have modern plastic services with decades ahead of them — their water-line calls are more often pressure-regulator and interior-run questions than buried failures.

How It Works
You explain what you are seeing; we ask the questions that sort urgent from schedulable and tell you any shutoff step worth taking now.
We test before we touch: pressure, meter, camera or fixture cycles — the evidence comes first, in view.
You hear what failed, why, and the repair paths with their costs — including the option of a smaller fix where one honestly exists.
The repair is completed and then proven under pressure or full flow before anything is closed or covered.
What failed, what was done, what to watch — documented for owners, landlords and tenants alike.
Know both shutoffs — house and meter side — and keep the meter box accessible and reasonably clear. Note your static pressure once: a regulator holding pressure in a healthy range spares every joint and appliance valve in the home.
Watch the yard after dry weeks for unexplained green or soft strips along the line's path, and read the meter monthly so a buried leak gets discovered by arithmetic before it is discovered by a sinkhole of a water bill. When landscaping, keep new trees off the line's route and dig anywhere near it by hand first.

Why Consider Us
Triangle turns over fast. Families arrive on orders, renters rotate each summer, and landlords carry keys for houses they may visit twice a year. Triangle-Plumber is built for that rhythm: short, clear explanations, written notes a landlord can act on from another state, and a pre-move walk-through habit that catches the dripping trap and the tired water heater before a new tenant finds them the hard way.
We also say plainly what is not ours to fix. A Prince William Water main issue, a shared townhome line owned by the HOA, a fixture a tenant damaged — you hear who owns the problem and what the next call should be, instead of a bill for guesswork.
Turnover is when plumbing problems surface. We check shutoffs, traps, disposals, and heater age at the moment a home changes hands, so surprises land on a checklist instead of a first night in a new place.
We explain, in plain terms, which repairs usually sit with the property owner and which day-to-day items sit with the tenant — then document the finding so both sides read the same note.
A meter test, a pressure reading, or a camera view comes first. The repair follows the evidence, and you see that evidence while we talk through the choices.
Call (855) 913-0016 at any hour. You get shutoff guidance for the situation in front of you first, then a visit matched to how urgent the problem actually is.

FAQs
Use the house shutoff. Close it fully, then check the meter: if the meter still moves, water is leaving between the meter and that valve — the yard service line. If the meter stops, the loss is inside the home's plumbing. That one test splits the problem in half. Tell us the result when you call, and the visit starts with locating instead of searching.
Gradual, whole-house decline usually means narrowing, not leaking: rust and scale building inside a galvanized service, or a pressure regulator drifting out of adjustment. A leak more often shows as a bill increase or a wet spot. Pressure testing — static versus flowing readings — separates the two on the first visit, and the pipe's material and age usually confirm which story you are in.
The standard split puts the utility's responsibility at the main and meter, and the property owner's responsibility on the line from the meter to the house and everything inside. Our boundary test documents exactly where your loss sits, which is the fact that decides responsibility — keep our written summary if you ever need to discuss it with the utility or an insurer.
Modern services are commonly run in polyethylene or copper, chosen for soil conditions, length, and local practice. Both outlast the galvanized and problem-era plastics they replace. We will explain which suits your run and why — including how the connection at the meter and the house entry is made — before the work is quoted, so the material decision is informed, not assumed.
Not necessarily. Where the route allows, a new line can be pulled through or alongside the old path with access pits at the ends, leaving most of the yard untouched. Open trenching is needed when the route bends, crosses other utilities, or the old line's path cannot be reused. Either way, we mark the route, the pits, and the restoration expectations in the plan before starting.
Yes, quietly. Escaping water erodes the soil supporting whatever is above it — driveway edges, walkways, even foundation backfill — and the surface failure can arrive weeks after the leak began. That is why a fast-spinning meter or a spreading wet area is treated as urgent: stopping the erosion early is far cheaper than rebuilding the surface it undermines.
It is a valve on the incoming line that caps the house's pressure at a set level, protecting fixtures, appliance valves, and joints from high street pressure. If your home has one and pressure turns erratic or low, the regulator itself may be failing. Not every home needs one — it depends on the pressure Prince William Water delivers at your street — and a gauge test during our visit answers the question with a number.
Most residential replacements in Triangle complete within a day or two of active work once locating and any required notifications are handled, with water restored the same day in typical cases. Longer runs, driveway crossings, and weather can extend that. We give you a written sequence — dig or pull, connect, test, restore — so you know which day holds what, and the meter-stillness proof closes the job.
Often, yes: rust sediment from a corroding galvanized line settles when water sits, then flushes out brown at the first draws. Occasional discoloration after utility work in the street is different and clears quickly. If the pattern repeats on your home's schedule — every Monday morning, every return from a trip — the line's interior is the likely source, and a material assessment belongs on the list.
If the rest of the line proves sound, absolutely — a spot repair is the right scope for an isolated joint failure in healthy pipe. The decision turns on what the excavation exposes: clean, full-sized pipe on both sides argues for the spot fix; rust, narrowing, or problem-era material argues for replacement. We show you the exposed section and let its condition make the case, either way.
Depth and exposure vary house by house. A shallower burial, a section crossing under a driveway where soil cover and frost behave differently, or a stretch near a vent or meter box with less insulation can freeze while deeper lines survive. After a freeze repair, we assess cover depth along the run and flag the shallow sections so insulation or deeper re-bedding can protect them next winter.
Check one outside faucet and, if you can, whether a neighbor has water — that separates a street outage from a house problem in a minute. Check your house valve is open and the meter area shows no flooding. Then call us at (855) 913-0016: we will walk the possibilities with you, and if the fault is your line or valve, we will come prepared to restore service; if it is a Prince William Water outage, you will know that too.
