FAQs

What makes high-performance PEX a smart upgrade for Dunlap homes?

PEX (cross-linked polyethylene) offers several advantages over traditional copper or CPVC piping. It resists scale and corrosion from Dunlap’s mineral-rich water, expands slightly if water freezes to reduce burst risk, and dampens water-hammer noise. Because the tubing is flexible, installers use fewer fittings and can snake it through existing walls, resulting in faster, cleaner retrofits and lower labor costs. PEX is also energy-efficient—its smooth interior and natural insulation value help maintain water temperature and reduce pump load.

Is PEX durable enough to handle our seasonal temperature swings?

Yes. High-performance PEX-A and PEX-B lines are rated for continuous service from 33 °F up to 200 °F and pressures of 80–100 psi, easily covering the extremes typical in Dunlap. The material’s ability to expand up to 8 % before cracking gives it superior freeze resistance compared with copper. UV-shielded pipe or insulated sleeves are used for any sections exposed to sunlight to preserve longevity, which is 50+ years under normal operating conditions.

How does PEX compare to copper or CPVC in terms of water quality and safety?

PEX piping is NSF-61 certified for potable water. Because it is non-metallic, it will not leach lead or pinhole-corrode, and it resists chlorine better than copper. It also prevents biofilm buildup thanks to its smoother bore. All fittings we use are no-lead brass or high-performance polymer and meet the 2024 International Plumbing Code and Tennessee state requirements.

Will my household be without water during a PEX repipe, and how long does the project take?

We stage work to minimize downtime. For a typical 2-bath Dunlap home, the full repipe takes 1–2 days: Day 1 we route new PEX lines through the attic or crawl space while the old system remains active; water is shut off for 2-4 hours when we make final tie-ins. Larger homes may require a second day for fixture connections and drywall touch-ups. We always leave at least one functioning bathroom overnight if a multi-day schedule is necessary.

Are permits or inspections required for a PEX upgrade in Dunlap?

Yes. Dunlap follows the Sequatchie County building department which adopts the 2021 IRC/IPC. We handle the permit application, pay the fee, and schedule the rough-in and final inspections. Using a licensed, insured plumbing contractor ensures the work is code-compliant, maintains your home insurance coverage, and protects manufacturer warranties.

How much does a PEX plumbing upgrade cost and what warranties do you provide?

Costs vary with home size and accessibility, but most Dunlap repipes run $3,500–$7,000 for a 1,500–2,500 sq ft residence, including drywall repair. We offer transparent, itemized estimates, 0 % short-term financing, and accept major credit cards. The PEX tubing carries a 25-year manufacturer warranty; our labor warranty is 10 years and transferable to new homeowners—an attractive selling point if you decide to put your house on the market.
