FAQs
What makes high-performance PEX piping a better choice than traditional copper or CPVC for Morristown homes?
PEX (cross-linked polyethylene) is flexible, corrosion-proof, and resistant to mineral buildup, which is important in Morristown’s moderately hard water. The pipe can be run in long, continuous lengths with fewer fittings, reducing potential leak points and installation time. Because it expands slightly under pressure, PEX is far less likely to burst during the freeze–thaw cycles common in North Jersey winters. It is also quieter than copper, resists electrolysis, and usually costs 25–40 % less installed. All PEX products we use are NSF-certified for potable water and carry a 25-year manufacturer warranty.
How long does a PEX repipe or pipe-upgrade project typically take in Morristown?
A full PEX repipe of an average 2-bath, 2,000 sq ft Morristown home usually takes 2–4 days. Day 1 is devoted to protecting floors and furnishings and running new main trunk lines. Day 2 focuses on branch lines to fixtures. Larger homes or projects that include water-heater relocation or manifold systems may require an extra day or two. Because PEX can be fished through existing cavities, most drywall openings are small and we patch them before we leave. Water service is normally restored at the end of each workday so you’re never without basic plumbing overnight.
Do I need permits or inspections for a PEX pipe upgrade in Morristown?
Yes. Morristown follows the New Jersey Uniform Construction Code, which classifies whole-house repiping as a plumbing alteration. We obtain the plumbing permit on your behalf, submit material specifications for the PEX and fittings, and schedule the rough-in and final inspections with the Morristown Building Department. Because PEX is already approved in the 2021 International Plumbing Code adopted by New Jersey, approvals are straightforward, but pressure-testing at 80 psi for 30 minutes is required before walls are closed. Permit fees typically range from $75 to $150 depending on fixture count.
How does the cost of upgrading to PEX compare to repairing my existing copper pipes?
Spot-repairing pin-holed copper may look cheaper upfront—$300–$600 per leak—but repeated leaks add up quickly. A whole-house PEX upgrade for a typical Morristown home runs $4,500–$8,500, including permits and drywall patches. Because PEX installation is faster and requires fewer fittings than copper, labor hours are 30–50 % lower. Energy savings from reduced heat loss and fewer future leaks can offset the upgrade cost within 5–7 years. Financing and utility rebates for water-conservation plumbing improvements can further reduce out-of-pocket expenses.
Is PEX safe for drinking water and does it affect water taste or odor?
All high-performance PEX tubing we install is ASTM F876/F877 and NSF/ANSI 61-certified for potable water. Independent lab tests show no significant leaching of VOCs, lead, or BPA. During the first few days after installation you may notice a slight plastic odor; flushing the lines clears it quickly. Studies by the Water Quality Association confirm that after the break-in period, PEX has no measurable impact on taste, odor, or water pH. We provide a written compliance statement and the manufacturer’s 25-year potable-water warranty.
How does PEX perform in Morristown’s cold winters, and what freeze protection steps are included?
PEX can expand up to three times its diameter and return to shape, allowing it to survive freezing better than copper or CPVC. For extra protection we install PEX inside conditioned spaces whenever practical, add insulation sleeves in exterior walls, and maintain minimum 18-inch burial depth on underground runs. Where pipes pass through unheated crawlspaces or garages, we include self-regulating heat tape connected to a GFCI outlet. These measures, combined with shut-off valves at hose bibbs, virtually eliminate winter freeze failures and are backed by our 10-year workmanship guarantee.
