Main Water Line Repair in Oregon
The service line is the one pipe with no shutoff between it and the street. When it fails, it fails at pressure, continuously, and the meter keeps counting.
Leak location before excavation. Trenchless replacement where the route allows it.
What the service line is
The water service line is the single pressurised pipe running from the municipal meter, or from a well, to the point where water enters your building. Everything in the house is downstream of it.
Two things make it different from any other pipe on the property. It is under constant pressure, so a failure leaks continuously rather than only when a fixture runs, often forty to eighty psi, twenty-four hours a day. And in most Oregon jurisdictions everything from the meter to the house is the property owner's responsibility, while the utility owns the meter and the main. A leak on your side is your bill in two senses: the repair and the water.
It is also usually buried at moderate depth with no intermediate valves, which is why locating a leak accurately matters so much. The difference between a located repair and an exploratory dig is the difference between one small excavation and a trench across the yard.
Signs it is leaking
The classic sign is a patch of ground that is wet, soft or unnaturally green when nothing explains it, and in an Oregon winter that is genuinely hard to spot, which is why service line leaks often run for months here before anyone notices.
More reliable indicators come from inside. Pressure that has dropped across the whole house, gradually or suddenly. A water bill that has stepped up without a change in habits. The sound of running water with every fixture closed. On a well system, a pump that cycles or runs continuously and never quite satisfies the pressure switch; that is the well-system equivalent and it burns out pumps.
The definitive check is the meter. Close every fixture and appliance in the building, then watch the meter dial or the leak indicator. If it moves at all, water is leaving the system. If it moves with the house shutoff closed as well, the leak is between the meter and that valve, the service line.
Escalating signs worth calling about immediately: water surfacing in the yard or the street, a sinkhole or depression forming along the route, water entering a crawl space or basement from outside, or any settlement crack that appears at the same time as the wet ground. A leaking service line washes soil out from under whatever is above it.
Wet patch in the yard that never dries? Call before it undermines something.

Nobody should open a trench on a guess. Leak location on a pressurised line is a real discipline and it is quick.
We start with a pressure test to confirm the loss is on your side of the meter and to establish its rate. Then acoustic detection: a pressurised leak makes a characteristic noise in the pipe and in the surrounding soil, and correlating equipment narrows it to a small area. On plastic lines, which transmit sound poorly, tracer gas or line tracing may be used instead. The route of the pipe is traced from the surface so the excavation follows it rather than searching for it.
The output is a marked spot and a depth. That single hour of work routinely saves several times its cost in excavation, and it tells you before you commit whether the leak is at one point or the line is failing generally, which is the repair-versus-replace decision.
Why Oregon service lines fail
Galvanized steel. Standard in pre-1960s construction. It corrodes internally, loses diameter and eventually perforates, usually as a pinhole first. A galvanized service line producing its first leak is not unlucky; it is finished, and the rest of it is the same age.
Polybutylene. Installed widely from the late 1970s into the mid 1990s, typically grey plastic. It becomes brittle and fails at fittings and along the pipe, often without warning. Where we find it, replacement is the recommendation regardless of the current leak.
Copper. Long-lived, but vulnerable to soil chemistry and to stray electrical current. Pinholes in buried copper often mean the whole run is exposed to the same conditions.
Older poly and undersized lines. Early polyethylene, plus lines sized for a smaller house than the one now standing on the lot.
Mechanical causes account for the rest: settlement, a trench cut across the line by another trade, root pressure, freeze damage on a shallow line east of the Cascades, and damage from vehicle loading where the line crosses a driveway.
A meter that turns with everything off is proof, not a theory.
Get the Leak LocatedRepair or replace
A spot repair makes sense when the leak is a single discrete failure in a line that is otherwise in good condition and has plenty of life left, a copper line damaged by a shovel, a fitting that has failed, a section crushed by vehicle loading. We excavate at the located point, cut out the damage and join in new pipe.
Replacement is the answer when the material itself is the problem. Galvanized, polybutylene and early poly all fail along their whole length, and repairing one hole in a line like that reliably produces a call about the next one within a year or two. It is also the answer when the line is undersized for the building, when it is too shallow for the freeze exposure at that address, or when there have already been multiple failures.
Replacement is a good moment to correct two other things at once: line size, if the house has been extended or the pressure has always been marginal, and the main shutoff, which on an older property is frequently a valve that no longer closes.
Trenchless replacement
A new service line does not always need an open trench. Where the route allows it, a new polyethylene line can be pulled through from a pit at the meter to a pit at the house, either along the path of the old pipe or on a new bore beside it.
That preserves driveways, patios, mature planting and, importantly, sidewalks and street surfaces that are expensive to cut and reinstate. On a service line crossing hardscape, it is usually the cheaper option overall even though the method itself costs more.
Its constraints are the usual ones: the corridor has to be clear of other utilities, which means locating gas, power, telecoms and the sewer first; the pits need somewhere to go; and the soil has to be workable. Where the route is open lawn at moderate depth, conventional excavation is often simpler and cheaper, and we will say so.
Cost, permits and the water bill
Length, depth and what sits on top drive the number, as with any buried line. Crossing a driveway, a sidewalk or a street adds surface reinstatement and, in the right of way, permits and sometimes traffic control. Work near the meter often requires coordination with the utility.
Service line work is permitted and inspected. We pull the permits, arrange the inspection, and include restoration in the quote, compacted backfill, matching surface reinstatement, lawn made good.
One thing worth doing while the repair is booked: contact your water utility about the bill. Many Oregon jurisdictions operate a leak adjustment policy that credits part of the excess consumption once a leak has been repaired, usually requiring the repair invoice as evidence and a claim within a set window. It is not automatic and nobody will offer it to you. Ask, and keep the paperwork.
We locate before we dig, it decides the size of the hole.

Main water line repair, answered
Close everything in the building and watch the meter. Movement means loss. Then close the house shutoff, if the meter still moves, the leak is between the meter and that valve, which is the service line and your responsibility in most Oregon jurisdictions.
Yes. Acoustic correlation, pressure testing and line tracing locate a pressurised leak to a small area, and we mark position and depth on the surface. On plastic lines, which carry sound poorly, tracer gas may be used instead.
By material. A single mechanical failure in sound copper is a repair. Galvanized, polybutylene or early poly fails along its whole length, so repairing one hole just schedules the next call. The location work tells us which situation you are in.
For a spot repair, a few hours. For a replacement, the changeover itself is usually a matter of hours even where the overall job runs a day or two, and we give you the window in advance.
Often partly, yes. Many Oregon utilities have a leak adjustment policy requiring proof of repair and a claim within a set period. It is never automatic, ask them directly and keep our invoice.
Lead service lines are rare in Oregon but do exist in a few older areas, sometimes as a lead gooseneck at the connection rather than a full line. Where we find lead, replacement is the recommendation and we coordinate with the utility on their portion.
Galvanized or poly service line? Replacement is usually the answer.
