The pipe between the street and your house
The water service line is a single underground pipe running from the water main in the street to your meter and main shutoff. Water service line repair means finding where that pipe leaks or breaks and fixing or replacing it.
Nobody sees it, so trouble shows up indirectly. You may lose pressure, hear nothing, find a wet lawn in January or open the meter lid to a spinning dial. Because the pipe is buried, finding the problem comes before fixing it. The City of Minnetonka reports a service line inventory under federal lead rules and lists 3,907 lines of unknown material, so ask the city utility about your line before you dig, according to its latest water report.
No water or a flooding yard from a broken service line
A broken service line can flood a yard or basement and leave the house with no water at all. We answer the 24/7 line at night and on weekends, and same-day appointments are offered when available.
Here is what to do while you wait.
- Close the main shutoff inside the house. If water still flows to the yard, the leak is likely ahead of the valve and the utility may need to shut it off outside.
- Look at the water meter. A dial that spins with everything off points to a leak past the meter.
- Keep people and pets off soft, soaked ground, which can hide a sinkhole around the pipe.
- If the water seems to come from the street side of the meter, call the City of Minnetonka Public Works utilities office as well.
- Photograph the wet area, the meter and any damage with the date visible.
- Move belongings out of the basement if water is coming through the wall.
Signs the buried line is leaking
A soggy strip of lawn that never dries, a bright green stripe of grass, a depression in the soil or a patch of melted snow on a cold day all point to water under the surface. Inside the house, look for a basement wall that is damp where the line enters.
Pressure and noise change too. A low-pressure complaint at every tap, a hiss near the meter or a bill that keeps rising suggest a leak. The meter test on our leak detection page tells you if water leaves with everything off.
Why pressure drops at the taps
Low water pressure has several causes, and the service line is only one. A partly shut main valve, a clogged pressure regulator, a failing shutoff, corrosion inside old supply pipe or a leak all reduce flow.
Check whether the problem is one fixture or the whole house. One tap with a weak stream is usually a clogged aerator or cartridge. The whole house points to the main valve, regulator or the service line itself. A pressure gauge on an outdoor spigot shows whether the pressure arriving is low, and the water pressure rules in Minnesota Rules chapter 4714 cover the topic. We read the gauge, not the code, when we diagnose.
Finding the exact leak before digging
Digging blind is expensive. We trace the pipe with a line locator, listen along its path with an acoustic ground microphone, and pressure test the line to confirm a loss. Where the route is unclear, a locating tool follows the pipe from the meter outward.
Once the spot is marked, the excavation can be a small hole instead of a trench across the lawn. This is the same approach described under buried line leaks on our leak detection page, here from the repair side.
Dig, trenchless or pipe bursting
The right method depends on the pipe, the route and what sits on top of it.
| Method | Best for | Trade-offs |
|---|---|---|
| Open trench dig. | Short runs, one clean break, easy lawn access. | Surface restoration of lawn, driveway or landscaping. |
| Spot repair. | A single leak found by tracing. | Only fixes that spot, and the rest of the aged pipe stays. |
| Trenchless pipe lining. | Sound route with a damaged inside. | Needs a clear path and may not suit every pipe or fitting. |
| Pipe bursting. | Replacing the whole line along its old path. | Needs entry and exit pits, and a pipe that can be burst. |
Not every method fits every property. A tree, a driveway, a fence or another utility may decide the choice. We explain the option that fits your yard.
Repairing a leak in the underground line
For a single leak on an otherwise good pipe, the plumber digs to the spot, cuts out the damaged piece and joins new pipe with the proper fittings. The excavation is backfilled in layers and the surface restored as agreed.
If the line is old, thin or leaking in several places, patching can turn into a yearly chore. Replacement is the cleaner answer in that case. A new service line is installed from the main connection point to the meter, and the water is turned back on only after a pressure test.
Burst or separated pipe inside the house is a different job, handled on our burst pipe repair page.
Minnetonka's service line inventory and your address
As of 2025, the City of Minnetonka reports 0 lead service lines and 13,722 non-lead lines, with 3,907 lines still listed as unknown material. We are not saying yours is any particular material. We are saying that a camera look or a short exposure of the pipe is a sensible question to ask when the line is open anyway.
Ask Minnetonka Public Works about the inventory entry for your address. Permit rules vary, so also ask the City of Minnetonka building department whether your project needs a permit before work starts.
Water main replacement questions
The water main in the street belongs to the city, not to the homeowner. If you think the main itself is broken, or the whole block lost water, call Minnetonka Public Works. Your plumber handles the line from the connection to your house and everything inside it.
What affects water service line repair cost
Underground work has more variables than most plumbing. You get a clear price before work starts.
Insurers differ on underground lines. Some policies cover a sudden break while others exclude wear, or offer an optional service line endorsement. Read your policy and call your insurer before work starts.
When the leak is on the city side
The utility is responsible for the main and the connection point. A leak between the meter and the street can fall on either side, depending on the local rules for your address, so call both. We close the valves, test which side is losing water and tell you what we find.
We serve Minnetonka and nearby towns, such as Eden Prairie and Plymouth, where lines and city rules may differ. Check that anyone you hire is licensed at the Minnesota DLI Check a License lookup.
Questions about water service line repair in Minnetonka
Yes. The 24/7 line is open around the clock, including nights and weekends, and same-day appointments are offered when available.
A spinning meter with everything off, a soggy strip of lawn, a bright green grass line or a wet basement wall at the entry point are the usual signs. We confirm it with tracing and a pressure test.
The city owns the main in the street. The pipe to your house is generally the property owner's concern, but the split varies. Ask Minnetonka Public Works about your address.
Not if we can avoid it. We locate the leak first so the dig can be small, and trenchless methods are an option on some lines.
The city reports 0 lead lines. Some are still listed as unknown material. Ask Minnetonka Public Works about your address, and ask us to look at the pipe when it is exposed.
A partly closed main, a failed regulator, corroded pipe or a leaking service line can each be the cause. We check the pressure at an outdoor spigot to narrow it.
The main under the street belongs to the city. We repair and replace the line from the main to your house. See our repiping page for pipes inside.
