FAQs
What makes PEX a good choice for plumbing upgrades in Fayetteville homes?
PEX (cross-linked polyethylene) is flexible, resists scale and chlorine, and tolerates Fayetteville’s seasonal temperature swings without becoming brittle. Its flexibility reduces the need for fittings, lowering potential leak points and installation labor costs—important for both new builds and retrofits in older Fayetteville neighborhoods.
Does PEX meet North Carolina (or Arkansas) plumbing codes?
Yes. Both North Carolina and Arkansas state plumbing codes recognize PEX tubing that carries an ASTM F876/F877 listing and an NSF-pw or CSA B137.5 certification. Our installers use code-approved tubing and follow local permit and inspection requirements, ensuring your upgrade is 100 % compliant.
Will PEX piping improve my water pressure or flow?
In many homes, yes. Because PEX can be routed in continuous runs with sweeping bends, friction losses are lower than with copper or CPVC systems that rely on multiple 90-degree elbows. We often design PEX home-run manifolds that deliver balanced pressure to each fixture, reducing the ‘shower goes cold when the toilet flushes’ effect common in older piping layouts.
How long does a typical PEX repipe take and will I be without water the entire time?
A full two-bathroom Fayetteville home usually takes 1–3 days. We stage the work so the water is only off during tie-ins—generally a few hours. You’ll have advance notice, and critical fixtures (like one bathroom) are prioritized to get back online first.
Is PEX safe for drinking water and does it affect taste?
PEX is certified for potable water and is free from lead and corrosion byproducts associated with some metal pipes. Most homeowners notice no taste difference; any mild ‘plastic’ taste that can occur in the first few days dissipates quickly after regular use and flushing.
What kind of warranty do you provide on PEX pipe upgrades?
We offer a 25-year manufacturer warranty on PEX tubing and a 10-year workmanship warranty on our installation. This covers material defects, leaks at fittings we install, and freeze-related failures when the system has been properly winterized according to our guidelines.
