FAQs
What makes modern PEX piping a better choice than traditional copper or CPVC for Flintville homes?
PEX (cross-linked polyethylene) is flexible, resistant to scale and chlorine, and far less prone to pinhole leaks or corrosion than copper. Unlike CPVC, it can handle freeze-thaw cycles without cracking, which is useful for Flintvilleâs variable winters. Its flexibility means fewer fittings and joints, reducing potential leak points and speeding up installation.
How long can I expect a new PEX plumbing system to last?
When installed correctly, PEX piping has an expected service life of 40â50+ years. It resists pitting, mineral buildup, and electrolysis that shortens copper life, and most leading manufacturers back their tubing with 25-year to lifetime limited warranties.
Will upgrading to PEX increase my homeâs water pressure or flow?
Yes. PEX systems often use a âhome-runâ manifold design, where each fixture gets its own dedicated line. This minimizes pressure drops when multiple fixtures run at once. The smooth interior of PEX tubing also promotes better flow compared with aging metal pipes that may have internal corrosion or scale.
Is PEX approved by local Flintville building codes and insurers?
Absolutely. Tennessee has adopted the International Residential Code (IRC) that fully recognizes PEX types A, B, and C. Flintvilleâs permitting office allows PEX for potable water supply and insurers typically view it favorably because of its durability and reduced leak risk. We always pull the proper permits and provide code-compliant work.
How disruptive is the repiping process and how long does it take?
Most single-family homes in Flintville can be completely repiped with PEX in 1â3 days. Because PEX can be snaked through existing cavities and requires fewer joints, we often access walls only at fixture locations, sparing you large sections of drywall removal. Water service is usually restored each evening so youâre never without plumbing overnight.
What does a PEX upgrade cost and are there long-term savings?
PEX repipes typically cost 20â40 % less than copper because the material is cheaper and labor hours are lower. In the long term, youâll save on reduced leak repairs, lower potential water damage claims, and improved energy efficiency when paired with a manifold (hot water reaches fixtures faster, reducing wasted water). Many homeowners see the investment recouped in maintenance savings and increased property value.
