What is Repiping?
Repiping is the process of completely replacing the old, deteriorating pipes in your home with new, modern piping materials. Unlike a spot repair that patches a single leak or damaged section, a full repipe removes and replaces all affected water supply lines, drain lines, or gas lines throughout the property. For many Cupertino homeowners living in homes built during the city’s major residential development boom of the 1960s through 1980s, the original galvanized steel or early copper plumbing is now 45 to 65 years old — well past its expected service life.
Over time, aging pipes corrode from the inside out, leading to restricted water flow, discolored water, pinhole leaks, and even hidden water damage behind walls and under slabs. A professional repipe restores your home’s plumbing system to peak performance, improves water quality, increases water pressure, and protects your property from costly future repairs. It also adds significant value to your home, which is especially important in Cupertino’s competitive real estate market.
Pro Tip: If you’re buying or selling a home in Cupertino, request a video camera inspection as part of your due diligence. Drain & Water offers free video camera inspections for homeowners, giving you a clear picture of your pipe condition before making any decisions.
Cupertino's Trusted Repiping Specialists
Our Cupertino Repiping Services
At Drain & Water, we provide a comprehensive range of repiping solutions tailored to the unique needs of Cupertino properties. Whether you need a single line replaced or a complete plumbing system overhaul, our licensed team (CA Contractors License #1026232) has you covered.
Sewer Line Repipe
From pinhole leaks in copper pipes to burst water lines, we repair all types of water leaks using durable materials and proven techniques.
Gas Line Repipe
Corroded or outdated gas lines are a serious safety hazard. Our C36-licensed plumbers replace aging gas piping to ensure safe, code-compliant delivery throughout your home.
Whole Home Repipe
For homes with widespread pipe failure, a whole home repipe replaces every water supply line, stop valve, and fitting in the house.
Drain Line Repipe
Persistent clogs, slow drains, and recurring backups often point to deteriorating drain pipes. We replace old drain lines with durable modern materials, restoring proper flow and preventing future drain repair emergencies.
Copper Repipe
Copper remains the gold standard for water supply lines. It’s highly resistant to corrosion, delivers excellent water quality, and can last 50+ years. We use Type L copper for superior wall thickness and durability.
PEX Repipe
Cross-linked polyethylene (PEX) piping is a flexible, cost-effective alternative that resists scale buildup and freezing. PEX installation is less invasive, often resulting in shorter project timelines and fewer access holes in your walls.
Pro Tip: Not sure which material is right for your home? Copper is ideal for longevity and resale value, while PEX offers flexibility and lower upfront cost. Our team will walk you through the pros and cons during your free estimate.
Learn more about the differences in our guide: PEX vs. Copper — What Type of Pipes Should I Use?
Low or inconsistent water pressure
Mineral buildup and internal corrosion narrow pipe diameter over time, reducing flow to faucets and showers.
Discolored or rusty water
Brown, yellow, or reddish water when you turn on the tap indicates corroding pipes leaching rust and sediment into your water supply.
Frequent leaks
If you’re calling a plumber for leak repairs more than once a year, the problem is systemic, not isolated.
Visible pipe corrosion
Green patina on copper, white mineral deposits, or flaking on exposed pipes in your garage, basement, or crawl space are clear indicators of deterioration.
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.
Recurring drain clogs
Persistent backups despite regular drain cleaning may signal collapsed or deteriorated drain pipes.
Unusual sounds
Banging, rattling, or whistling in your walls when water is running can indicate loose fittings or pipe degradation.
Slab leaks
Warm spots on your floor, unexplained increases in your water bill, or the sound of running water when all fixtures are off may point to a leak beneath your foundation.
Common Signs It May Be Time for a Repiping
Cupertino homes built in the 1960s–1980s are prime candidates for repiping. Here are the warning signs every homeowner should watch for.
Pro Tip: Don’t wait for a catastrophic pipe failure. If your Cupertino home is over 40 years old and still has its original plumbing, schedule a proactive leak detection inspection with Drain & Water. Catching problems early can save you thousands in water damage restoration.

Recommended Piping Materials
Choosing the right pipe material is one of the most important decisions in a repipe project. Here’s what we recommend for Cupertino homes:
Copper (Type L)
The industry standard for water supply lines. Copper is naturally antimicrobial, highly durable, resistant to UV exposure, and has a proven lifespan of 50–70+ years. It’s the preferred choice for homeowners who prioritize longevity and resale value. Copper is also fully recyclable, making it an environmentally responsible option.
PEX (Cross-Linked Polyethylene)
A flexible, modern alternative that resists scale buildup, corrosion, and freezing. PEX requires fewer connections and fittings, which means fewer potential leak points. It’s quieter than copper (no water hammer), installs faster, and is typically more affordable. PEX is an excellent choice for whole home repipes where budget and minimal wall disruption are priorities.
ABS / PVC
For drain, waste, and vent (DWV) systems, we use ABS or PVC piping depending on your home’s existing configuration and local code requirements. These materials are lightweight, corrosion-proof, and provide smooth interior surfaces that resist buildup and clogs.
HDPE (for Trenchless Applications)
For sewer lateral replacements using pipe bursting or horizontal directional drilling, high-density polyethylene offers exceptional flexibility and joint-free installation.
Pro Tip: Avoid mixing metals in your plumbing system. Connecting copper directly to galvanized steel without a dielectric union causes galvanic corrosion — accelerating pipe failure. A professional repipe eliminates this risk entirely.

What Cupertino Homeowners Should Know Before Preparing for a Full Repipe
A whole home repipe is a significant but manageable project. Here’s how to prepare:
Understand the scope. A full repipe typically involves opening small sections of drywall to access pipes inside walls and ceilings. Your technician will explain exactly where access points will be made before work begins.
Plan for temporary water shutoff. Water will be turned off during portions of the installation, usually for a few hours at a time. Plan to have bottled water on hand and schedule the work when it’s least disruptive to your household.
Clear access areas. Move furniture, stored items, and personal belongings away from walls where plumbers will need to work — particularly in kitchens, bathrooms, laundry rooms, and the garage.
Protect valuables and flooring. While our team takes every precaution to protect your home, it’s a good idea to cover nearby furniture and remove fragile items from shelves near work areas.
Know your pipe material. Before your estimate, check if you know what type of pipes your home currently has. Common materials in Cupertino homes include galvanized steel, copper, cast iron (for drains), and early PEX or polybutylene. If you’re unsure, our inspection will identify everything.
Check your homeowner’s insurance. Some policies cover water damage from sudden pipe failures but not gradual leaks. A proactive repipe can prevent claims and may even lower your premiums.
Verify permits are pulled. Always confirm that your contractor pulls the required City of Cupertino building permits. This protects you legally and is essential for future home sales.
Pro Tip: If your Cupertino home was built before 1986, there’s a chance your plumbing contains lead solder. A full repipe eliminates this health risk entirely, ensuring safe, clean water for your family. Ask Drain & Water about water line services if you have concerns about your water quality.
Frequently Asked Questions About Repiping in Cupertino
How long does a whole home repipe take?
Common signs include unexplained increases in your water bill, the sound of running water when fixtures are off, damp spots on walls or floors, and musty odors. If your home was built before the 1980s, aging pipes increase the likelihood of hidden leaks. A professional leak detection service can confirm whether a leak exists and pinpoint its exact location.
What is the difference between copper and PEX repiping?
A slab leak occurs when a water or sewer pipe beneath your home’s concrete foundation develops a crack or hole. Many Cupertino homes were built on slab foundations with copper pipes that corrode over time, especially in areas with mineral-rich water. Drain & Water offers specialized slab leak detection and repair using non-invasive methods.
Will repiping damage my walls or property?
Yes. At Drain & Water, we use electronic sensors, acoustic listening devices, thermal imaging cameras, and pressure testing to locate leaks without cutting into walls or breaking concrete. Our goal is always to find the leak with minimal disruption to your Cupertino home.
Do I need a permit for repiping in Cupertino?
Most residential leak detection inspections in Cupertino take between one and three hours, depending on the complexity of your plumbing system and the number of potential leak locations. Larger homes or properties with multiple suspected leaks may require additional time for a thorough assessment.
How do I know if my home needs a repipe or just a repair?
Absolutely. Even a slow drip can waste thousands of gallons of water annually and create conditions for mold growth, wood rot, and foundation damage. In Cupertino’s clay-heavy soil, water from a leak can cause the ground beneath your foundation to shift, leading to cracks and structural issues. Early detection is always the most cost-effective approach.
Can you repipe my home without digging up my yard?
Galvanized steel pipes, commonly found in homes built before the 1970s, are highly susceptible to internal corrosion and rust buildup that leads to leaks. Copper pipes, while more durable, can develop pinhole leaks over time due to water chemistry and soil conditions. If your home has aging pipes, consider asking about repiping options.
What type of warranty does Drain & Water offer on repipe work?
Yes. Drain & Water provides 24/7 emergency plumbing services throughout Cupertino and Santa Clara County. If you suspect an active leak causing water damage, call us immediately at (408) 564-0580 and we’ll dispatch a technician as quickly as possible.
