Repiping Services in Gilroy
Professional Repipe Specialists You Can Trust
Is your Gilroy home showing signs of aging pipes? Drain and Water provides expert repiping services in Gilroy, CA — from whole home repipes to copper, PEX, sewer, gas, and drain line replacements. Learn when it’s time to repipe, what materials to choose, and why local homeowners trust our repipe specialists.
What is Repiping?
Repiping is the process of removing and replacing the existing plumbing pipes throughout part or all of a building. Unlike a spot repair or a pipe patch, repiping addresses the entire piping system — or a significant section of it — to eliminate widespread corrosion, material degradation, or code-compliance issues that cannot be resolved with localized fixes.
For Gilroy homeowners, repiping typically involves replacing old water supply lines, drain lines, sewer lines, or gas lines with modern, durable materials such as copper (Type L) or cross-linked polyethylene (PEX). The goal is to restore full water pressure, eliminate leaks, improve water quality, and extend the functional lifespan of the home’s plumbing infrastructure by 40 to 50+ years.
Repiping is not the same as drain repair or sewer line repair, which target individual sections of damaged pipe. A repipe is a system-level upgrade — and when done by experienced repipe specialists, it is one of the highest-value improvements you can make to a residential property.
Pro Tip: If your Gilroy home was built before 1985, there is a strong chance your plumbing includes galvanized steel pipes, which are highly prone to internal corrosion and restricted water flow. A free camera inspection can reveal the true condition of your pipes before problems escalate.
Gilroy's Trusted Repiping Specialists
Repiping Services We Offer in Gilroy
At Drain and Water, we provide a full range of repipe plumbing services tailored to the specific needs of Gilroy residential properties. Whether you need a single line replaced or a complete whole-home repipe, our licensed technicians handle every phase of the project — from initial inspection through final testing and cleanup.
Whole-Home Repipe
A whole home repipe replaces every water supply line, and potentially drain and gas lines, throughout the entire property. This is typically recommended when multiple sections of piping show signs of failure or when the home’s original plumbing has reached the end of its useful life. Most whole home repipes for Gilroy single-family residences are completed in one to three days.
Copper Repipe
Copper remains the gold standard for water supply lines due to its corrosion resistance, longevity (50+ years), and proven track record in California residential plumbing. We use Type L copper, which is thicker-walled and better suited for underground and high-pressure applications.
PEX Repipe
PEX-A tubing offers flexibility, freeze resistance, and faster installation times compared to copper. It is an excellent choice for Gilroy homes where accessibility is limited or where homeowners want to reduce installation time. PEX also resists scale buildup and chlorine degradation, making it ideal for the South Bay’s municipal water supply.
Sewer Line Repipe
Older sewer lines made from clay, Orangeburg, or cast iron deteriorate over time, leading to root intrusion, bellied sections, and chronic backups. We replace failing sewer lines with modern ABS or PVC piping, often using trenchless methods to minimize disruption to your Gilroy property. Our team also offers sewer line replacement and CIPP pipe lining when conditions allow.
Gas Line Repipe
Corroded or damaged gas lines pose serious safety risks. Our gas line services include full gas line repipes using code-compliant materials such as CSST (corrugated stainless steel tubing) or black iron pipe. We ensure all gas line work meets California building codes and passes local inspection.
Drain Line Repipe
If your home’s interior drain lines are made of outdated materials like galvanized steel or deteriorating cast iron, a drain line repipe can restore proper drainage flow and eliminate recurring clogs. We coordinate drain line replacements with our drain cleaning and hydro jetting services for a complete system refresh.
Pro Tip: PEX-A (expansion-style) fittings create a stronger, more reliable connection than PEX-B crimp fittings. If you are comparing repipe quotes in Gilroy, ask your contractor which type of PEX they use — it makes a difference in long-term performance.

Low Water Pressure at Multiple Fixtures
If water pressure has gradually declined throughout your home (not just at one faucet), mineral buildup and internal corrosion are likely restricting flow inside your aging pipes.
Rust-Colored or Discolored Water
Brown, yellow, or reddish water when you turn on the tap is a telltale sign of corroding pipes.
Recurring Pinhole Leaks
A single pinhole leak is a warning. Two or more pinhole leaks in different locations signal systemic pipe failure — patching individual spots won’t solve the underlying corrosion happening throughout the system.
Visible Corrosion on Exposed Pipes
Green, white, or bluish mineral deposits on pipes under sinks, in crawl spaces, or in your garage indicate active corrosion and imminent failure risk.
Water temperature fluctuations
If your shower goes cold unexpectedly or takes a long time to heat up, corroded pipes may be restricting hot water flow.
Frequent Plumbing Repairs
If you’re calling a plumber multiple times a year for leaks, clogs, or water quality issues, the cost of repeated repairs often exceeds the investment in a full repipe.
Banging, Rattling, or Noisy Pipes
Unusual sounds when you turn water on or off can indicate pressure irregularities, loose fittings, or deteriorating pipe sections within your walls.
Your Home Was Built Before 1985 and Has Never Been Repiped
Pipes from this era are at or past their expected service life. A proactive inspection is strongly recommended.
Common Signs It May Be Time for a Repiping
Many Gilroy homeowners do not realize their plumbing system is failing until a major problem occurs. Here are the most common warning signs that indicate your home may need a partial or full repipe.
Pro Tip: Even if you are only experiencing one of these signs, schedule a free camera inspection. Small problems in aging pipe systems tend to compound quickly, and early detection can save thousands in emergency repair and water damage restoration.

Recommended Piping Materials for Gilroy Homes
Choosing the right pipe material is one of the most important decisions in any repipe project. The best option depends on your home’s layout, water conditions, budget, and long-term goals. Here are the materials we most commonly recommend for Gilroy residential repipes:
Copper (Type L)
- Lifespan: 50–70+ years
- Best for: Water supply lines, underground applications
- Advantages: Proven reliability, excellent corrosion resistance, adds resale value, accepted by all California building codes
- Considerations: Higher material cost, requires soldered joints
PEX (Cross-Linked Polyethylene)
- Lifespan: 40–50+ years
- Best for: Water supply lines, retrofit repipes in finished homes
- Advantages: Flexible (fewer fittings needed), freeze-resistant, faster installation, resistant to scale and chlorine
- Considerations: Cannot be used outdoors (UV sensitive), relatively newer track record than copper
ABS / PVC (Drain, Waste, and Vent Lines)
- Lifespan: 50–80+ years
- Best for: Drain lines, sewer lines, vent stacks
- Advantages: Lightweight, chemical-resistant, smooth interior resists buildup
- Considerations: Not suitable for hot water supply lines
CSST (Corrugated Stainless Steel Tubing)
- Best for: Gas line repipes
- Advantages: Flexible, faster to install than rigid black iron, fewer joints (fewer potential leak points)
- Considerations: Requires proper bonding and grounding per code
Pro Tip: Many Gilroy homeowners choose copper for the main supply lines and PEX-A for interior branch lines — this hybrid approach balances durability, cost, and installation speed. Ask your Drain and Water technician about this option during your consultation.

Our Repiping Process
Drain and Water follows a structured, transparent process for every repipe project in Gilroy. We keep you informed at every stage so there are no surprises.
Step 1: Free Consultation and Camera Inspection
We begin with a thorough on-site evaluation of your plumbing system. Our technicians use professional-grade video camera inspection equipment to assess the interior condition of your pipes — identifying corrosion, root intrusion, cracks, buildup, and other issues that are invisible from the outside.
Step 2: Customized Repipe Plan and Transparent Estimate
Based on the inspection results, we develop a repipe plan tailored to your home’s specific needs. You will receive a detailed, itemized estimate that includes material options (copper, PEX, or hybrid), scope of work, project timeline, and any permit requirements. We answer every question before work begins.
Step 3: Permit Coordination
For whole home repipes and significant plumbing modifications, we handle all permit applications with the City of Gilroy Building Division. All work is performed to current California Plumbing Code (CPC) standards.
Step 4: Professional Pipe Replacement
Our licensed technicians (C36, C12, C42 classifications) remove the old piping and install new lines with precision. We protect your home’s interior, minimize wall and ceiling openings, and clean up as we go. Most residential repipes are completed in one to three days.
Step 5: Pressure Testing and Final Inspection
After installation, we perform pressure tests on all new lines to verify integrity. We also conduct a post-installation camera inspection on drain and sewer lines to confirm proper slope, connections, and flow.
Step 6: Cleanup, Walkthrough, and Warranty
We walk you through the completed work, answer any remaining questions, and provide documentation including your Limited Lifetime Warranty on qualifying services. Patching and drywall restoration can be coordinated as needed.

What Gilroy Homeowners Should Know Before Preparing for a Full Repipe
A whole home repipe is a significant project, but proper preparation makes the process smoother and faster. Here is what Gilroy homeowners should keep in mind:
Water will be shut off during installation. Plan for one to three days without running water in your home. Fill containers for drinking and cooking in advance, and consider alternate bathing arrangements if the project spans more than one day.
Access is critical. Our technicians will need access to walls, ceilings, crawl spaces, and potentially the attic. Move furniture, wall décor, and stored items away from plumbing walls before the crew arrives.
Permits may be required. For whole home repipes, the City of Gilroy typically requires a plumbing permit and inspection. Drain and Water handles all permitting on your behalf.
Drywall openings are necessary but manageable. Accessing pipes behind walls requires cutting small openings. We minimize these cuts and can coordinate drywall patching and restoration after the repipe is complete.
Notify your household. Make sure everyone in the home knows the project timeline and understands that water, and potentially gas, will be temporarily unavailable.
Ask about material options upfront. Understanding the differences between copper and PEX — and the option for a hybrid approach — helps you make an informed decision that fits your budget and long-term goals.
Pro Tip: If you are planning a kitchen or bathroom remodel in the near future, scheduling it alongside your repipe can save money. Walls will already be opened, which reduces additional labor and drywall costs.
Frequently Asked Questions About Repiping
How long does a whole home repipe take in Gilroy?
Most single-family home repipes in Gilroy are completed in one to three days, depending on the size of the home, the number of fixtures, and the accessibility of the existing plumbing. Drain and Water provides a clear timeline during your free estimate so you can plan accordingly.
What is the difference between copper and PEX piping?
Copper is a rigid metal pipe with a 50–70+ year lifespan and a long track record of reliability. PEX is a flexible plastic tubing with a 40–50+ year lifespan that installs faster and resists freezing. Both are excellent choices, and our technicians can help you decide which material — or combination — best suits your Gilroy home.
Will repiping damage my walls and ceilings?
Some drywall cuts are necessary to access pipes behind walls, but our team minimizes the size and number of openings. We clean up throughout the project, and we can coordinate drywall patching and restoration once the repipe is complete.
Do I need a permit for repiping in Gilroy?
Yes. The City of Gilroy requires plumbing permits for whole home repipes and significant plumbing modifications. Drain and Water handles all permit applications, inspections, and code compliance on your behalf, so you do not need to manage the process yourself.
Can I stay in my home during the repipe?
In most cases, yes. Water will be temporarily shut off during the work, but many homeowners stay in the home throughout the project. We recommend filling containers with water in advance and planning for short-term disruptions to your routine.
How do I know if I need a full repipe or just a repair?
If you are experiencing isolated issues — a single leak or one slow drain — a targeted repair may be sufficient. However, if you are seeing widespread corrosion, multiple leaks, discolored water at several fixtures, or your pipes are made of outdated materials, a full repipe is the more cost-effective and lasting solution.
What warranty does Drain and Water offer on repipe work?
We offer a Limited Lifetime Warranty on qualifying repipe services. This covers workmanship and provides long-term protection for your investment. We also provide post-installation documentation and are available for follow-up support whenever you need it.
