Water Line Repair & Replacement in Meridian, ID
Water line repair fixes the buried service line that runs from your water meter to the house, the pipe that supplies everything indoors. It is a different job from repiping, which replaces the supply pipes inside the walls.
A leaking service line wastes water around the clock and can soften the yard or undermine a driveway. If you suspect one, we can confirm it and give you a price before digging.
Which part of the line is yours?
In Meridian, the city maintains the water lines in the public right of way, including the main in the street. The service line on your side, from the meter to the house, is the owner's responsibility.
If the leak is at the meter itself or on the street side, call Meridian Water at 208-888-5242. They handle their portion at no cost to you.
Everything from the meter to the house is private plumbing. That is the part a plumber repairs, and it is usually the part that fails.
Ownership works differently in Eagle, where the utility that owns the meter depends on which water provider serves your street.
If the meter test shows the leak is inside the house instead, leak detection is the next step, and a pipe that split in the cold is covered under burst pipe repair.
Service lines in Ada County's older neighborhoods near Main Street are the most likely to be galvanized.
Signs your service line is leaking
Service line leaks are underground, so the signs are indirect.
- The meter's leak indicator moves even with the main shutoff at the house closed.
- A strip of lawn between the meter and the house stays green or soggy in a dry spell.
- Water pressure throughout the house has dropped over time.
- You hear running water near the foundation when nothing is on.
- The water bill rose without a change in use.
The meter test on our leak detection page is the fastest way to confirm whether the leak is between the meter and the house.
Service line materials in Meridian homes
The material depends largely on when your home was built.
| Material | Where it shows up | What to know |
|---|---|---|
| Galvanized steel | Older Old Town homes | Rusts from the inside, loses pressure, eventually leaks. |
| Copper | Many homes from the 1970s to 1990s | Durable but can pinhole, especially at bends. |
| Polyethylene (poly) | Many newer homes | Flexible and freeze tolerant, fittings can loosen. |
| PEX or PVC | Some newer service lines | Durable, depends on correct burial depth and fittings. |
General patterns. The actual material is confirmed when the line is exposed.
Repair a section or replace the line?
If the line is in good shape except for one leak, such as a loose fitting or a single puncture, a spot repair is usually the right call. The plumber locates the leak, digs a small pit, and replaces that section.
If the line is old galvanized steel, has leaked more than once, or is undersized for today's household, replacement makes more sense. A new line restores full pressure and resets the clock.
Replacement does not always mean a long trench. Depending on soil and distance, a new line can sometimes be pulled or bored under the yard between two small pits. Before any digging, buried utilities are marked through Idaho's 811 locate service.
Check the pressure regulator too
Many homes have a pressure reducing valve where the service line enters. If street pressure runs high and that valve has failed, the extra pressure strains every joint in the house and can shorten the life of a new line.
A plumber can test house pressure with a gauge on a hose bib in a few minutes. It is worth doing whenever the service line is repaired or replaced.
What affects the cost of water line work
Service line jobs vary mainly with distance and what sits on top of the pipe.
- The distance from the meter to the house.
- Whether the line runs under lawn, landscaping, a driveway, or a walkway.
- Spot repair versus full replacement.
- Trenching versus boring or pulling a new line.
- Permit, inspection, and surface restoration.

Water service line questions
Who is responsible for the water line from the street to my house?
The City of Meridian maintains the public right of way and the meter side. The line from the meter to your house is the owner's responsibility.
How do I know if my service line is leaking?
Close the main shutoff at the house and check the meter's leak indicator. If it still moves, the leak is likely between the meter and the house.
Can a water line be replaced without trenching the whole yard?
Often, yes. Depending on the soil and distance, a new line can be bored or pulled through between two small pits.
Is a water line the same as repiping?
No. The service line runs underground from the meter to the house. Repiping replaces the supply pipes inside the house.
Why is my water pressure low in the whole house?
A narrowing galvanized service line, a leak, or a failing pressure regulator can all cause it. Testing pressure at the house narrows it down.
Do I need a permit?
Service line replacement is permitted work, and the plumber handles the permit and inspection.
