Jet Pipe Plumbing provides water line repair in Sunnyvale, CA, serving homeowners throughout San Carlos, Santa Clara, and the South Bay. Whether you’re dealing with a pinhole leak, a burst pipe, or a corroded section of line, our licensed technicians diagnose the issue and give you an honest repair-vs-replace recommendation.

Common Water Line Problems We Repair

The most common issues we repair include pinhole leaks in copper or galvanized pipe, burst pipes from age or pressure issues, corroded sections that have started to leak, and joints or fittings that have failed over time.

Pipe Leak Repair

Targeted repair of a leaking supply line — pinhole leaks, joint failures, and cracked sections located by inspection and fixed with copper or matching material.

Main Water Line Repair

Repair of the primary underground line bringing water from the municipal supply into your home, including burst sections, failed fittings, and corrosion damage. When the line is corroded end to end, patching it twice costs more than putting in a new one.

Active Leak Response

Same-day service for leaks causing active water damage. We locate the source by inspection, stop the leak, and tell you whether a repair or a section replacement is the right fix. If water is running now, shut off the main and call us as soon as we open.

Same-Day Repair Service

A leaking or burst water line is often urgent, since it can cause water damage the longer it goes unaddressed. We prioritize these calls and offer same-day service in many cases to get the leak stopped and the line repaired quickly.

Repair vs. Replace: An Honest Assessment

Not every leak calls for a full line replacement. If a pipe is otherwise in good condition, a targeted repair may be all that’s needed. But if a section has multiple failure points or is clearly near the end of its life, we’ll recommend whole-house water line replacement instead of repeatedly patching the same aging pipe.

Pinhole Leaks

Pinhole leaks typically develop from internal pipe corrosion and can be easy to miss until water damage shows up nearby. We locate the exact failure point and repair or replace the affected section as needed.

Burst Pipes

A burst pipe is one of the more urgent calls we respond to, since it can release a significant amount of water quickly. We isolate the line, stop the flow, and repair the break, then check nearby sections of pipe for similar signs of stress or age.

What Our Customers Say

Corroded and Aging Pipe Sections

Corrosion inside a pipe restricts flow and weakens the pipe wall over time, eventually leading to a leak or burst. When we find corrosion during a repair, we’ll let you know whether it’s isolated or a sign that more of the system may need attention soon.

Flat-Rate Repair Pricing

Every water line repair includes a flat-rate quote agreed before work begins, backed by a workmanship warranty on the repair itself, with no hidden fees added afterward.

Preventing Future Line Failures

Once a repair is complete, there are a few practical steps that reduce the odds of a repeat call. Keeping water pressure within a safe range with a pressure-reducing valve protects pipe joints from stress over time, and addressing hard water with a softener slows the internal corrosion that leads to pinhole leaks. We’ll flag any pressure or water quality issues we notice while making a repair, since correcting the underlying condition is often more effective than repairing the same type of failure again a year or two later in a different spot along the same line.

Serving Sunnyvale and the South Bay

We repair water lines throughout Sunnyvale and nearby San Carlos, Santa Clara, San Jose, and Redwood City. Contact us for same-day repair, or ask about whole-house repiping if your home has recurring pipe issues.
