Jet Pipe Plumbing provides water line repiping in Sunnyvale, CA, serving homeowners throughout Santa Clara, San Jose, and the South Bay. We default to copper for whole-house repiping because of its 50+ year lifespan in Bay Area soil, though PEX or HDPE piping is available for specific situations where it’s the better fit.
Why Homes Need Repiping
Older homes with galvanized steel or aging copper pipes often develop low water pressure, discolored water, or recurring leaks as the interior of the pipe corrodes. Whole-house repiping replaces the entire supply line system at once, rather than patching one leak after another as pipes continue to fail.
Whole House Water Repiping
Complete replacement of all water supply pipes throughout your home, from the main line connection to every faucet, shower, and appliance.
Main Water Line Replacement
Full replacement of the primary water line bringing fresh water from the municipal supply or well into your home’s plumbing system.
Partial Water Line Repiping
Selective replacement of damaged or corroded sections, targeting specific problem areas like a single bathroom, kitchen, or leaking branch line.
Copper vs. PEX Repiping
Copper is our default recommendation because it lasts 50 or more years in Bay Area soil and meets local code across every jurisdiction we work in. PEX is more affordable and flexible to install, which makes it a reasonable option in specific situations, such as tight access spaces, though it doesn’t match copper’s long-term lifespan.

Minimizing Disruption During Repiping
Repiping an entire home understandably raises questions about how much of the house will be disrupted. Our crews work room by room, cutting small, targeted access points in drywall rather than opening up entire walls, and we protect flooring and furniture as we move through the home. Water is typically shut off only in short intervals as each section is connected, and drywall patching is included at the end of the project so you’re not left coordinating a separate contractor for repairs.
Your Repipe, Step by Step
A repipe is a planned job with a fixed order. The part most homeowners do not hear about in advance is the city: two inspections, one before the walls are closed and one after.
Free on-site assessment
A technician checks what the pipes are made of, what shape they are in, and how we reach them, then confirms what the house needs.
Price in writing
You get the price before anything is scheduled. Financing is available for repipe projects.
Permit
Repipe work requires a city permit. When the project includes the main water line, we draw the plan and get the permit from the city.
Installation, 1 to 3 days
The crew works room by room through small access openings, and water is shut off only in short intervals. Copper is our standard for water supply lines.
First inspection, walls still open
The city inspector checks the new pipe against code before anything is covered. The tests depend on the project and include a pressure test, pipe type, and pipe diameter.
Patching and final inspection
After approval we patch the drywall and backfill any trench. A second inspection after everything is closed confirms the job is complete. In most homes it is a formality.
In San Jose, the city also requires a grounding rod bonded to the water line. We plan for it from the first visit.

Frequently Asked Questions
Everything homeowners ask us about water line replacement
Water line replacement costs vary based on the line's length, material (copper, PEX, or HDPE), depth, and whether trenchless methods are needed. Copper costs more upfront but lasts 50+ years, often the better long-term value. Partial repiping costs less than a whole-house repipe. Get an exact price with our free, no-obligation estimate.
Repair usually works for one isolated leak, a faulty valve, or low pressure at a single fixture. Full replacement is likely needed if you have rusty or discolored water, dropping pressure house-wide, repeat leaks, or old galvanized pipes. Not sure which you need? A free inspection gives you a clear, no-pressure answer.
Copper is our default for Bay Area homes: it lasts 50+ years, handles local water chemistry well, and meets code. PEX is flexible, faster, and more budget-friendly, great for new construction. HDPE suits underground trenchless main line installs. The right pick depends on your home and budget — we'll recommend one after inspection.
Most water line replacements take 1–2 days, including cleanup, up to 3 days depending on access and excavation needs. We use careful digging, protective coverings, and full site restoration to limit disruption. You won't need to leave home, though water to the affected lines is briefly shut off during the work.
Yes. Repipe work requires a city permit. When the project includes the main water line, we draw the plan and get the permit from the city. The city then inspects the work twice: once before anything is covered and once after the walls are closed.
Our 25-year warranty on whole-house copper repiping covers all joints, fittings, and connections we install, with full repair or re-do at no charge for parts and labor if a covered leak occurs. It excludes damage from freezing, physical impact, third-party changes, or seismic events. Ask your tech for full details.
