PEX is the most common choice for repiping and new construction today because it's flexible, resists freeze-cracking better than rigid pipe, and costs less to install. Copper lasts the longest and handles heat and UV exposure better, but costs more in both materials and labor. PVC is used mainly for drain, waste, and vent lines rather than pressurized water supply. Which one is "right" depends on whether you're running supply lines or drain lines, and how much budget versus longevity matters to you.
PEX is flexible plastic tubing that has become the standard for residential water supply lines. It bends around corners without needing as many fittings as rigid pipe, which speeds up installation and reduces labor cost. It resists bursting from freezing better than copper or rigid PVC because it can expand slightly under pressure. It's not UV-stable, so it can't be used outdoors in direct sunlight or exposed runs, and it's not rated for high-heat applications the way copper is.
Copper has been the standard for supply lines for generations, and for good reason — it lasts 50+ years in most conditions, handles heat well, is naturally resistant to bacteria growth, and holds up outdoors and in exposed locations. The tradeoffs are cost (both material and the more time-intensive soldered joints) and, in some water conditions, gradual pinhole corrosion over decades. It's still frequently used for water heater connections and short exposed runs even in homes that are otherwise repiped in PEX.
Standard PVC is used almost exclusively for drain, waste, and vent lines rather than pressurized water supply — it's not rated for hot water or high pressure. CPVC (chlorinated PVC) is a variant that is rated for hot and cold water supply and is sometimes used as a lower-cost alternative to copper, though it has become less common as PEX has taken over that role. For drain lines, PVC is durable, inexpensive, and the standard choice in nearly all modern Oklahoma construction.
For a whole-home repipe, PEX typically costs meaningfully less than copper once labor is factored in, since fewer fittings and faster installation reduce the hours involved. Copper costs more upfront but requires less long-term thought once installed. PVC for drain lines is the least expensive of the three but isn't a substitute for supply piping. We'll walk through the tradeoffs for your specific home and give a free, itemized estimate before recommending a material — the right answer changes based on your home's age, layout, and how long you plan to stay in it.
We'll recommend the right material for your specific home, not just what's easiest for us to install.

Copper still generally outlasts PEX, but PEX's freeze resistance and lower installation cost make it the practical choice for most residential repipes today.
Yes, and it's common — many homes use copper for the water heater connection and any exposed or high-heat runs, with PEX for the rest of the distribution system, connected with the appropriate transition fittings.
Some people notice a very slight taste difference immediately after installation, which typically fades as the system is used. It's certified safe for potable water under NSF standards.
Signs include frequent pinhole leaks, persistently low water pressure not explained by a single fixture, visibly corroded or discolored pipe, or galvanized steel piping (common in homes built before the 1960s) which is well past its expected lifespan. A plumber can assess your specific pipe condition and tell you honestly whether a full repipe or targeted repairs make more sense.
