Water Line Replacement Process

Here's How We Handle It

First, we’ll assess your situation and give you a straight answer about repair versus replacement. Many times, what looks like a simple fix actually needs a full line replacement to prevent future problems.

We locate your existing water line and plan the most efficient route to minimize yard disruption. If we can use trenchless methods, we will. If we need to excavate, we’ll map out exactly where we’re digging before we start.

During the work, we handle permits, coordinate with the city, and keep your water service interrupted for the shortest time possible. Most residential water line replacements are completed in one to two days, depending on the complexity and distance from the street connection.

Complete Water Line Services

What's Included in the Job

You get a complete water line replacement from the street connection to your house, including all fittings and connections. We handle the city permits and coordinate any required inspections.

Our work includes pressure testing the new line, backfilling and compacting excavated areas, and restoring your yard to reasonable condition. We use quality materials designed for Mountain View’s soil conditions and local water pressure requirements.

For emergency water line breaks, we can often provide temporary service while planning the permanent replacement. This keeps you from being without water while we order materials and schedule the full job properly.

How do I know if I need water line repair or replacement?

If your water line is over 30 years old, showing multiple leak points, or made from outdated materials like galvanized steel, replacement usually makes more sense than repair. Signs pointing toward replacement include consistently low water pressure throughout the house, multiple recent repairs on the same line, or discovering the pipe material is prone to failure. We’ll assess your specific situation and give you an honest recommendation based on the line’s condition, your home’s age, and what we find during our inspection.

What are the signs of a broken underground water line?

The most obvious signs are wet spots in your yard that don’t dry out, unusually high water bills, and low water pressure inside your house. You might also notice your water meter running even when no water is being used inside. Other signs include soggy areas near your water line’s path, unusually green patches of grass, or hearing water running when everything inside is turned off. If you’re experiencing multiple symptoms, especially after recent ground settling or construction nearby, it’s worth having the line inspected before a small leak becomes a major break.

How much yard damage should I expect during replacement?

It depends on your specific situation and whether we can use trenchless methods. For trenchless replacement, we typically need access points at each end with minimal digging in between. Traditional excavation requires a trench from your house to the street connection, usually 2-3 feet wide. We’ll map out the most direct route that avoids major landscaping when possible. Most of our Mountain View customers are surprised at how quickly the yard recovers after we backfill and compact properly. We can’t replant your landscaping, but we’ll leave the area ready for you to restore.

How long does water line replacement take in Mountain View?

Most residential water line replacements take one to two days, depending on the distance from street to house and soil conditions. The actual work time is usually 6-8 hours, but we factor in permit coordination, material delivery, and any unexpected conditions we find underground. Emergency repairs can often be completed the same day, though we might install temporary service first if we need to order specific materials. Mountain View’s permit process is fairly straightforward, which helps keep projects on schedule compared to some neighboring cities.

Will I have water during the replacement process?

You’ll be without water for several hours during the actual connection work, typically 4-6 hours depending on the complexity. We schedule this work to minimize disruption and can often coordinate with your schedule for the water shutoff period. For emergency situations, we can sometimes install temporary service to restore water while we complete the permanent replacement over the following days. We’ll give you advance notice of exactly when your water will be off and when it will be restored.

Do you handle permits and city coordination for Mountain View?

Yes, we handle all permit applications and coordinate required inspections with Mountain View’s building department. This includes the initial permit application, scheduling inspections during the work, and ensuring everything meets local codes before we complete the job. Mountain View requires permits for water line replacement work, and we’re familiar with their specific requirements and typical processing times. The permit cost is separate from our labor, but we handle all the paperwork and scheduling so you don’t have to deal with the city bureaucracy yourself.
