Main Water Service Line

Water Line Repair & Replacement in Nampa, ID

The water service line is the buried pipe that carries drinking water from the meter to your house. When it leaks, cracks or corrodes, the signs show up in the yard, on the water bill or at every faucet at once. We repair and replace service lines for homes across Nampa, Idaho.

This is a different job from repiping. Repiping replaces the pipes inside the house. Water line work happens underground between the meter and the foundation, and it involves excavation or trenchless boring, permits and a locate before any digging.

Sound Familiar?

A Wet Strip in the Yard, a Meter That Never Stops, or Weak Pressure Everywhere

People rarely call asking for a service line. They call because a strip of lawn between the street and the house stays green or soggy, because the meter spins with every tap closed, or because pressure dropped at every fixture at the same time.

In Nampa, one extra check saves confusion. Many homes also have a buried pressurized irrigation line, which is a completely separate system. A wet spot with a still water meter usually points to the irrigation line. A wet spot with a running meter points to the drinking water service line covered on this page.

Shut the main at the house and watch the meter. If it still turns, the leak is between the meter and your shutoff, which is the service line.

Matching the Fix to the Problem

Some service line problems need one repaired section. Others mean the whole run is at the end of its life.

How It Is Done

Trenching, Boring and What Happens at the Meter

Every job starts with an 811 utility locate, which marks buried gas, power and communication lines before any digging. For a single leak, we excavate at the leak, repair the section and pressure-test it before backfilling.

For a full replacement, the new line can be laid in an open trench or pulled through with a trenchless boring tool that avoids trenching across lawns and driveways. Modern service lines are usually polyethylene or copper, buried deep enough to stay below the frost line and pressure-tested to the Uniform Plumbing Code (UPC) before backfill.

The City of Nampa sets qualification requirements for excavation contractors installing private water service lines outside the building, and the work is permitted. If pipe inside the house is also failing, pairing this job with whole-home repiping avoids a second disruption.

Pinpointing Before Digging Saves Money

Digging in the wrong spot is the most expensive way to find a service line leak. Acoustic equipment can narrow an underground leak to a small area first, so the excavation is short and targeted.

That is why many service line jobs start with electronic leak detection. If the line has already split open with water pooling at the surface, the leak often reveals itself, and our broken pipe crew can respond around the clock.

Pricing

What Water Line Work Costs Depends On

Line length, depth and what sits on top of the line drive the cost. A short repair under grass is a small job compared with a full replacement under a driveway.

Many homeowner policies exclude underground service lines unless you added a service line endorsement. Check your policy before assuming coverage.

Questions

Water Service Line Questions

Who is responsible for the water line from the meter to my house?

The line on the property side of the meter is generally the homeowner's responsibility. The utility's side of the meter is theirs. If you are unsure where the boundary sits, ask the city's water division before paying for repairs.

Can a water line be replaced without digging a trench?

Often, yes. Trenchless boring pulls a new line underground between small access pits, which spares lawns, landscaping and driveways.

Why is my water pressure low everywhere?

A corroded galvanized service line, a leak on the line or a failing pressure-reducing valve are the usual causes. Testing pressure at the house tells us which one it is.

Is a leaking service line an emergency?

A major break with water pooling or flowing is urgent and handled 24/7. A slow leak should still be fixed soon, because it wastes water and can undermine soil near the foundation.

Do you repair water lines outside Nampa?

Yes, including Middleton, ID and the other surrounding towns, with permits handled through the right local or state office.
