What is Repiping?
Repiping is the process of removing old, deteriorating, or damaged plumbing pipes and replacing them with new, code-compliant piping materials. Unlike a simple pipe repair that patches a single leak, repiping addresses your entire plumbing system — or targeted sections of it — to restore proper water flow, eliminate contamination risks, and prevent future failures.
A typical repiping project involves:
Shutting off and draining the existing water system
Removing or bypassing old pipes (galvanized steel, polybutylene, cast iron, etc.)
Installing new supply lines for both hot and cold water
Pressure testing the new system for leaks
Patching and restoring walls or ceilings affected during installation
For most Mountain View homes, a residential repipe can be completed in 2 to 5 days depending on the size of the property, number of fixtures, and piping material selected. Larger or multi-story homes may take slightly longer.
Pro Tip: Before your repipe begins, ask your plumber to perform a video camera inspection of your existing drain and sewer lines. This helps identify hidden issues like root intrusion or bellied pipes that could cause problems down the road.
Mountain View's Trusted Repiping Specialists
Repiping Services We Offer in Mountain View
At Drain & Water, we don’t just handle one type of repipe — we offer comprehensive pipe replacement solutions for every system in your home:
Whole-Home Repipe
Complete replacement of all water supply lines throughout your house. Ideal for homes with widespread corrosion, galvanized steel pipes, or polybutylene plumbing that has reached the end of its lifespan.
Copper Repipe
Copper remains the gold standard for residential plumbing. It’s durable, bacteria-resistant, recyclable, and can last 50–70+ years. We use Type L copper for superior wall thickness and longevity. Learn more about copper vs. PEX piping.
PEX Repipe
PEX (Cross-Linked Polyethylene) is a flexible, corrosion-resistant alternative that’s faster to install and more budget-friendly than copper. PEX is color-coded (red for hot, blue for cold) and ideal for retrofits where minimal wall disruption is a priority.
Sewer Line Repipe
Replacement of your main sewer line and branch drains using durable materials. If you’re experiencing recurring backups, foul odors, or your sewer camera inspection reveals cracks and root intrusion, a sewer line repipe may be the most cost-effective long-term solution.
Gas Line Repipe
Aging or corroded gas lines are a serious safety hazard. We replace outdated gas piping with code-compliant materials to ensure safe operation of your furnace, water heater, stove, and other gas appliances.
Drain Line Repipe
Persistent slow drains, recurring clogs, or deteriorating cast iron drain pipes often call for a full drain replacement rather than repeated repairs.
Pro Tip: If your Mountain View home has a mix of old galvanized and newer copper pipes, the connection points between dissimilar metals are especially vulnerable to corrosion. A full repipe eliminates these weak links entirely.

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
Many Mountain View homes built in the 1950s–1970s still have galvanized steel or early copper pipes that have exceeded their expected lifespan.
Common Signs It May Be Time for a Repiping
Not sure if your Mountain View home needs a repipe? Watch for these warning signs.
Pro Tip: Even if you’re only experiencing one of these symptoms, schedule a leak detection service before the problem escalates. Catching pipe failure early can save thousands in water damage repairs.

Recommended Piping Materials
Choosing the right pipe material is one of the most important decisions in a repiping project. Here’s what we recommend for Mountain View homes:
Copper (Type L)
Best for: Long-term durability, exposed applications, and homes where maximum lifespan is the priority
Lifespan: 50–70+ years
Advantages: Bacteria-resistant, recyclable, excellent temperature regulation, adds property value
Considerations: Higher upfront cost; requires soldered joints
PEX (Cross-Linked Polyethylene)
Best for: Budget-conscious homeowners, retrofits, and homes where minimal wall disruption is important
Lifespan: 40–50 years
Advantages: Flexible, corrosion-resistant, freeze-resistant, color-coded for easy identification, faster installation
Considerations: Cannot be used outdoors (UV sensitive); not recyclable
CPVC (Chlorinated Polyvinyl Chloride)
Best for: Hot and cold water supply lines in residential applications
Lifespan: 40–50 years
Advantages: Affordable, corrosion-resistant, heat-tolerant
Considerations: Can become brittle over time; less flexible than PEX
Materials We Replace
Galvanized Steel — Prone to rust, internal buildup, and lead contamination. No longer up to California building code.
Polybutylene — Known for premature failure and splitting. If your home has gray plastic pipes with copper or aluminum fittings, replacement is strongly recommended.
Lead Pipes — A serious health hazard. Immediate replacement is essential.

Pro Tip: Mountain View’s water quality and soil conditions can affect pipe longevity. Ask your Drain & Water technician about which material performs best for your specific neighborhood and soil type.

Our Repiping Process in Mountain View: What to Expect
At Drain & Water, we’ve refined our repiping process to deliver quality results with minimal disruption to your Mountain View home:
Step 1: Free Consultation & Inspection
We start with a thorough evaluation of your existing plumbing system, including a complimentary video camera inspection for drain lines. We assess pipe material, age, condition, water pressure, and the number of fixtures in your home.
Step 2: Custom Proposal & Material Selection
Based on our findings, we present a detailed proposal with material options (copper, PEX, or hybrid), a clear project timeline, and transparent pricing. We’ll walk you through the pros and cons of each option so you can make an informed decision.
Step 3: Preparation & Protection
Before work begins, we protect your floors, furniture, and belongings with drop cloths and plastic sheeting. We’ll advise you on how to prepare — including clearing areas around walls where pipes run and planning for brief water shutoffs.
Step 4: Pipe Removal & Installation
Our licensed technicians remove or bypass old pipes and install new supply lines throughout your home. We use strategic access points to minimize wall and ceiling openings. For sewer and drain line repipes, we may utilize trenchless methods like pipe bursting or CIPP pipe lining to avoid excavation.
Step 5: Pressure Testing & Inspection
Every new system is pressure tested to verify there are no leaks. We ensure all connections meet California plumbing code and schedule any required city inspections.
Step 6: Wall Patching & Cleanup
We patch all access points and leave your home clean. Our goal is to make it look like we were never there — except for the dramatically improved water quality and pressure.
Step 7: Final Walkthrough & Warranty
We walk you through the completed work, answer any questions, and provide warranty documentation. Drain & Water stands behind every repipe with industry-leading warranties.
What Mountain View Homeowners Should Know Before Preparing for a Full Repipe
A whole home repipe is a significant investment in your property. Here’s what to keep in mind before the project begins:
Understand your current pipe material. Knowing whether you have galvanized steel, copper, polybutylene, or cast iron helps your plumber plan the project accurately. If you’re unsure, we can identify your pipe material during our free inspection.
Plan for temporary water shutoffs. During the repipe, water will need to be turned off for portions of the day. Most homeowners can stay in their home throughout the process, but plan to have bottled water on hand and schedule showers around the work timeline.
Clear access areas. Move furniture, stored items, and wall decorations away from walls where pipes run — typically kitchens, bathrooms, laundry rooms, and utility closets. This helps our crew work efficiently and protects your belongings.
Check if permits are required. In Mountain View, most whole home repipes require a plumbing permit from the City of Mountain View Building Division. Drain & Water handles all permitting on your behalf.
Consider upgrading your water heater at the same time. If your water heater is more than 10 years old, bundling a water heater replacement with your repipe can save on labor costs and ensure your entire system is working together optimally.
Ask about trenchless options for sewer lines. If your sewer or drain lines also need replacement, trenchless methods like horizontal directional drilling or pipe bursting can save your yard from excavation.
Pro Tip: If you’re planning a kitchen or bathroom remodel in the near future, coordinate it with your repipe. Opening walls for new pipes is the perfect time to update layouts, add fixtures, or reroute plumbing — and it avoids paying for wall access twice.
Frequently Asked Questions About Repiping in Mountain View
How long does a whole home repipe take in Mountain View?
Most residential repipes are completed in 2 to 5 business days, depending on the size of your home, the number of fixtures, and the piping material selected. Drain & Water works efficiently to minimize disruption and restore your water service as quickly as possible. We’ll provide a clear timeline before work begins.
What is the difference between repiping and pipe relining?
Repiping involves physically removing old pipes and installing brand-new ones, while pipe relining (CIPP) creates a new pipe inside the existing one using an epoxy-coated liner. Relining is typically used for sewer and drain lines and is less invasive, while repiping is the standard approach for water supply lines. Your Drain & Water technician can recommend the best method for your situation.
Can I stay in my home during the repiping process?
Yes, in most cases you can remain in your home while the repipe is underway. Our team works section by section to maintain partial water access during the day and restores full service each evening. We communicate all planned shutoffs in advance so you can plan accordingly.
How do I know if I need a full repipe or just a repair?
If you’re dealing with an isolated leak or a single corroded section, a targeted pipe repair may be sufficient. However, if you’re experiencing multiple leaks, widespread low water pressure, discolored water, or your pipes are over 40 years old, a full repipe is typically the more reliable and cost-effective long-term solution.
What piping material does Drain & Water recommend?
We most commonly install copper (Type L) and PEX, and we offer hybrid solutions as well. The best material depends on your budget, property type, water quality, and long-term goals. Read our detailed comparison: PEX vs. Copper.
Will repiping increase my home's value?
Absolutely. Updated plumbing is a major selling point for Mountain View buyers, especially in a market where homes regularly sell for over $1.5 million. A modern piping system gives buyers confidence, simplifies home inspections, and can eliminate deal-breaking red flags during the sale process.
Does Drain & Water offer warranties on repiping work?
Yes. We provide industry-leading limited lifetime warranties on our repiping workmanship, and the piping materials we install carry their own manufacturer warranties. We’ll provide full warranty documentation upon project completion so you have peace of mind for years to come.
