FAQs

What are the main advantages of upgrading to PEX piping over traditional copper or PVC in Blountville homes?

PEX (cross-linked polyethylene) offers superior flexibility, corrosion resistance, and cost effectiveness. Because the tubing can bend around corners, it usually requires fewer fittings, which minimizes potential leak points. PEX is also immune to scale buildup and pin-hole corrosion that can plague copper in our mineral-rich local water supply. Compared with rigid PVC, PEX is quieter, tolerates higher pressure, and can handle both hot and cold lines without additional insulation or solvents. These benefits translate to a longer service life, lower maintenance, and faster installation times.

How long does PEX plumbing last, and what warranties do you offer?

High-quality PEX piping is rated for 50+ years of service under normal residential conditions, and field studies show it often outlasts copper. We install Uponor and Viega ASTM-certified tubing that carries a 25-year manufacturer warranty on material defects when installed by a licensed professional. Our company backs that with a 10-year workmanship guarantee covering labor and fittings, so homeowners have double protection on their investment.

Can PEX piping withstand Blountville’s temperature fluctuations and potential freezing?

Yes. PEX remains flexible down to –40 °F, far below the coldest temperatures recorded in Sullivan County. In the rare event that water does freeze inside the line, the tubing can expand up to three times its diameter without bursting and will return to its original shape once thawed. While we still recommend standard winterization measures—such as proper insulation and sealing of crawl-space vents—PEX gives an extra margin of safety against freeze-breaks that copper or CPVC cannot match.

Will upgrading to PEX disrupt my household, and how long does the installation take?

Most repipe projects are completed in one to three days, depending on home size and accessibility. Because PEX is flexible, we can often snake it through existing wall cavities, attics, and crawl spaces without major demolition. We schedule water shut-offs in short segments, so you’re rarely without running water for more than a couple of hours at a time. Our crew lays protective coverings, cleans up daily, and performs a final pressure test and walkthrough before leaving.

Is PEX safe for drinking water, and does it affect water taste or quality?

PEX meets NSF/ANSI 61 standards for potable water and is approved by the Tennessee Department of Environment & Conservation. Unlike some metal pipes, it leaches no lead, heavy metals, or phthalates. Independent studies show any initial plastic taste dissipates after the first few days of use; flushing the system during startup eliminates most of it immediately. The smooth interior walls also resist biofilm formation, helping maintain water clarity and taste over time.

How much does a PEX pipe upgrade cost in Blountville, and are financing options available?

Prices vary with home size, number of fixtures, and accessibility, but most full-house repipes range from $4,000 to $9,000. This includes new lines, fittings, shut-off valves, permits, and post-installation inspection. We provide a free in-home assessment and written quote with no obligation. For budget flexibility, we offer 0% interest financing for 12 months and extended low-APR plans up to 60 months through our lending partner. Insurance discounts and water-efficiency rebates may further offset costs.
