FAQs
What is PEX plumbing and why is it recommended for pipe upgrades in Crossville homes?
PEX (cross-linked polyethylene) is a flexible, high-density plastic tubing approved by the International Plumbing Code and the State of Tennessee for residential use. It is highly resistant to scale, chlorine, and pin-hole leaks, making it ideal for the hard-water conditions frequently found around Crossville. Because it can bend around corners with fewer fittings, it shortens installation time and reduces leak points, giving homeowners a reliable, future-proof piping system.
How does PEX compare to copper or CPVC in terms of durability and cost?
Copper is strong but expensive and vulnerable to acidic water and corrosion. CPVC is less costly than copper but becomes brittle over time and can crack during Crossville’s winter freezes. PEX, by contrast, costs 30–40 % less than copper on average, is not affected by corrosion, and has a life expectancy of 50+ years. Its flexibility also allows us to make long, continuous runs, which lowers labor hours and fitting costs—savings that are passed directly to you.
Will upgrading to PEX disrupt my daily routine, and how long does a typical repipe take?
Our certified technicians use a “home-run” technique that pulls new PEX lines through walls and attic spaces with minimal drywall removal. Most Crossville single-family homes can be fully repiped in 1–2 days. We stage work so that cold-water service is restored every evening, meaning you are rarely without running water for more than a few hours at a time. We also handle patching and painting of any small access holes we create.
Does PEX plumbing resist the freezing temperatures common on the Cumberland Plateau?
Yes. PEX can expand up to three times its diameter without rupturing, giving it a much higher freeze-break resistance than copper or CPVC. While proper insulation is still recommended, homeowners on the Plateau appreciate PEX’s added margin of safety during the sub-20 °F cold snaps Crossville occasionally experiences.
Is PEX safe for drinking water, and does it affect water taste or quality?
PEX tubing is NSF/ANSI 61 certified for potable water use and has been rigorously tested for chemical leaching. Independent studies show it does not introduce harmful contaminants at detectable levels. Most residents notice no change in taste; some report an improvement because PEX does not impart metallic flavors the way older galvanized or corroded copper pipes can.
What kind of warranty and maintenance does PEX piping require after installation?
We install only Tier-1, PEX-A tubing backed by a 25-year manufacturer’s warranty on materials. Our workmanship is warrantied for 10 years, and both are fully transferable if you sell your Crossville property. PEX requires no special maintenance—just treat your plumbing system as you normally would. Annual water-heater flushes and routine fixture inspections are sufficient to keep your new PEX pipes performing at their best.
