Two good materials, one hard-water valley. The right answer depends on your house, not a slogan.
Inspectors mis-flag it. We verify the pipe and fittings before a word about repiping.
We read the fittings and your situation, then tell you straight. Sometimes the answer is wait.
Two real numbers on your home, quoted straight - not a single take-it-or-leave-it figure.
Once you have decided to repipe out of Kitec, you get one real material choice: copper or PEX-A. Both are proven. Both beat what you are pulling out. Anyone who tells you one is always right is selling that one. Here is the honest comparison for a Las Vegas home.
Copper is the traditional answer – rigid metal pipe, soldered joints, the standard for generations. PEX-A is modern flexible plastic tubing, the highest-quality grade of PEX, run in longer continuous lengths with fewer fittings. We use Uponor PEX-A specifically. Note the contrast with Kitec: PEX-A is all-plastic with proper fittings, not the plastic-and-brass hybrid that failed.
PEX-A is usually the cheaper repipe. In the Valley a PEX-A repipe commonly lands around $3,000 to $6,000, while copper runs closer to $4,500 to $8,000. Larger or custom homes with full interior work push higher, into the $7,500 to $14,000 range and occasionally up toward $18,000 on big custom floor plans. PEX installs faster too – fewer joints, flexible runs – so you pay less in labor and spend less time with the water off.
Both will outlast your Kitec by a wide margin. Copper, done right, can run 50-plus years. Quality PEX-A is rated for decades and comes with strong manufacturer warranties. For a normal home, neither is going to be the thing that fails on you next. This is close to a tie on paper.
Here is where Las Vegas tilts the comparison. Our hard water is not just rough on brass – over long timeframes it can be rough on copper too. Aggressive water chemistry can pit and thin copper from the inside over the years. PEX-A does not corrode, does not pit, and does not care about mineral content. In our specific water, that is a real point in PEX’s favor, and it is not a small one given that hard water is exactly what killed the Kitec you are replacing.
Copper transmits sound. You get the classic water-hammer bang and the hiss of fast flow through metal. PEX is quieter by nature – the flexible tubing dampens noise instead of ringing with it. In a two-story home with bedrooms over bathrooms, that difference is something you actually notice at night.
This is the one argument that still favors copper. Some buyers and agents read copper as premium and PEX as builder-grade, fair or not. On a higher-end home where the buyer pool expects copper, that perception can matter. On most homes it is a wash, because the thing that moves the sale is that Kitec is gone and the plumbing is new. A clean repipe of either material clears the flag that was actually hurting you.
For most Las Vegas homes, we lean PEX-A. It costs less, installs faster, shrugs off our hard water better than copper does over the long haul, and runs quieter. For a standard family home, that is the stronger value, and the hard-water point is the one that keeps us there.
We lean copper in specific cases. A high-end custom home where resale perception genuinely matters. An owner who simply wants metal and plans to stay for decades. A layout where copper’s rigidity solves a particular routing problem. Those are real reasons, and when they apply we say copper without hesitation.
What we will not do is pretend there is one answer for every house. There is not.
Take a Rhodes Ranch two-story from 2003, mid-range home, family staying put, budget matters. We would put PEX-A in that house and feel good about it – lower cost, faster install, better in our water, quieter over the kids’ bedrooms. Move that same decision to a custom Summerlin home where the owner expects copper and is selling in a few years, and copper earns its higher price. Same valley, same Kitec problem, two honest answers.
The right material for your repipe comes down to your home, your budget, how long you are staying, and your water. That is a short conversation, not a hard sell. Tell us about your house and we will tell you which way we would go and why – including when we would spend more on copper for you rather than less on PEX.
