Is It Time to Repipe Your Fresno Home? Signs, Costs & What to Expect
If your Fresno home was built before the 1990s and you've never replaced the plumbing, there's a good chance your pipes are quietly failing right now. Whole-home repiping is one of the most significant — and most overlooked — home improvements a Central Valley homeowner can make. This guide walks you through the warning signs, the process, and what it realistically costs to repipe a home in Fresno, Clovis, Visalia, or anywhere across the Central Valley.
What Is Whole-Home Repiping?
Repiping is the process of replacing all — or a significant portion — of a home's existing water supply pipes with new material. Unlike a spot repair that patches one corroded section, repiping addresses the entire system from the main shutoff to every fixture in the home. The result is a fresh, fully functional plumbing system that will last decades — and immediately improves water quality, pressure, and safety.
6 Warning Signs Your Fresno Home Needs Repiping
1. Consistently low water pressure throughout the home. When pressure is low at every fixture — not just one — corroded or scaled-up pipes restricting flow through the entire supply system is the most likely cause. This is especially common in Central Valley homes with original galvanized steel pipes, which accumulate mineral deposits from the region's hard water over decades.
2. Rusty, brown, or discolored water. Discolored water from multiple hot and cold faucets — not just the water heater — means your pipes themselves are corroding from the inside. This is a serious health and infrastructure concern that requires immediate evaluation.
3. Frequent leaks in different parts of the home. One leak is a repair. Two or three leaks in different locations within a short period is a pattern — and a pattern means the pipes have reached the end of their useful life. Patching individual leaks becomes more expensive than repiping when failures become frequent.
4. Visible corrosion on exposed pipes. Check under sinks, in the garage, and in the crawl space or attic. Green staining on copper pipes or orange rust on galvanized pipes means corrosion has already begun. What you can see is rarely the worst of it.
5. Fluctuating water temperature. Pipes that have scaled up internally can cause pressure imbalances that make water temperature erratic in the shower — a sign of restricted flow from aging supply lines.
6. Your home is over 40 years old with original plumbing. In Fresno and the Central Valley, many homes built between the 1950s and 1980s were plumbed with galvanized steel a material with an expected lifespan of 40–70 years. If your home is in that range and has never been repiped, a professional evaluation is strongly recommended.
What Pipe Materials Are Used for Repiping in California?
The two most common materials used for residential repiping in California's Central Valley are:
PEX (Cross-linked polyethylene): The most popular choice for modern repiping projects. PEX is flexible, highly resistant to the mineral scale caused by Central Valley hard water, freeze-resistant, and significantly less expensive to install than copper. It carries a 25-year manufacturer warranty and is approved under the California Plumbing Code.
Copper: The gold standard for residential plumbing, copper pipe is durable, biostatic (resistant to bacteria), and carries strong resale value recognition. It costs more than PEX and requires soldering — but in high-end renovations or homes where the buyer expects copper, it remains the preferred choice.
Zuni's Plumbing's licensed technicians will recommend the right material for your home's size, budget, and age after a thorough evaluation.

What to Expect During the Repiping Process
Most whole-home repiping projects in the Central Valley are completed in 2–4 days, depending on home size. Water will be shut off during active work hours but restored each evening. Our licensed crew minimizes drywall cuts by routing new lines through existing access points wherever possible. After the new pipes are pressure-tested and inspected by a licensed plumber, any drywall openings are patched and the water is turned back on.
