Repipe Materials: PEX vs. Copper

Flexible and budget-friendly, or proven and rigid? Here's how PEX and copper stack up for a Florida repipe.

PEX vs. copper at a glance

Both are proven, code-approved materials for home water supply lines. The differences come down to flexibility, cost, lifespan, and how each one holds up to Florida's hard water:

PEX versus copper repipe material comparison
Factor PEX Copper
Up-front cost Lower Higher
Flexibility Flexible, fewer fittings Rigid
Corrosion resistance Resists corrosion Can pinhole in hard water
Install speed Faster Slower (soldered joints)
Sun / outdoor use Not UV-rated Tolerates sun
Track record Newer Long, proven
Recyclable Limited Yes

PEX: pros and cons

PEX (cross-linked polyethylene) is flexible plastic tubing that has become a default choice for many modern repipes. Its strengths and limits:

  • Flexible, fewer fittings: it bends around corners, so there are fewer joints that could ever leak.
  • Lower cost: the material and labor are typically less than copper, which matters on a whole-home repipe.
  • Corrosion-resistant: it won't pinhole the way copper can in aggressive or hard water.
  • Faster install: a flexible run goes in quicker, meaning less time and less disruption in your home.
  • Con — UV-sensitive: sunlight degrades PEX, so it isn't used for outdoor or sun-exposed runs.
  • Con — newer track record: it performs well, but its real-world history is shorter than copper's decades of use.

Copper: pros and cons

Copper has been the trusted standard for generations and still has real advantages — along with a couple of Florida-specific drawbacks:

  • Long, proven track record: decades of use mean its behavior is very well understood.
  • Durable: it tolerates heat and pressure well and isn't affected by sunlight.
  • Recyclable: copper is a recyclable metal, which some homeowners value.
  • Con — higher cost: both the material and the soldered-joint labor cost more than PEX.
  • Con — pinhole leaks: hard water can corrode copper from the inside over time, creating tiny pinhole leaks.

Which makes sense for a Florida repipe?

For many Brevard County homes, hard water, slab routing, and budget all point toward PEX — it resists the corrosion our water can cause, flexes easily through a slab home, and costs less. But it's genuinely situational.

Copper still makes sense for some homeowners, especially where a proven material is the priority or for specific exposed runs. Hard water is the recurring theme either way — it's why a softener often comes up during a repipe. Start with do I need a repipe? and how hard water affects Brevard homes.

What does a repipe cost?

Repipe pricing depends on your home's size, how many fixtures and bathrooms it has, how accessible the lines are, and which material you choose — so any single number is a range, not a quote.

About pricing

Because every home is different, we won't print a figure that won't match yours. A whole-home repipe is a meaningful investment, and PEX generally costs less than copper for the same job. We'll measure your home and give you a clear, written number before any work begins. [GATHER: confirm/adjust local pricing with Anna's].

Frequently asked questions

PEX vs. copper — which is better?
Neither is universally better; it depends on the job. PEX is flexible, corrosion-resistant, and usually cheaper and faster to install, which suits many Florida repipes. Copper has a longer proven track record and is very durable, but it costs more and can develop pinhole leaks in hard water. The right pick is situational.
Is PEX safe for drinking water?
Yes. PEX is approved for potable water and is used in homes across the country for both hot and cold supply lines. It's certified to the same drinking-water standards as other approved materials, which is one reason it has become a common choice for modern repipes.
Does copper corrode in Florida?
It can. Copper resists most corrosion, but aggressive or hard water can attack it from the inside over time, leading to pinhole leaks. Brevard County's hard water makes this worth considering, which is why a water softener or choosing PEX can be part of the conversation during a repipe.
Which lasts longer, PEX or copper?
Copper has the longer proven history and can last for decades when conditions are favorable. Quality PEX is also rated to last for decades but has a shorter real-world track record. In hard water, copper's lifespan can be cut short by pinhole leaks, so 'longest-lasting' depends heavily on your water.
