FAQs
Why should I upgrade aging galvanized or CPVC plumbing to copper lines in my Maynardville home?
Copper is extremely durable, naturally corrosion-resistant, and rated for 50+ years of service. Unlike galvanized steel, it will not rust shut, and unlike older CPVC it tolerates higher water pressures and temperatures without becoming brittle. Upgrading improves flow, raises resale value, eliminates metallic or plastic tastes, and reduces the risk of sudden leaks that can cause expensive water damage.
What are the signs that my existing copper lines need to be replaced or upsized?
Early warning signs include pin-hole leaks, bluish-green staining around joints, unexplained drops in water pressure when multiple fixtures run, and water bills that creep up despite no lifestyle change. Homes that were repiped with thinner Type M copper in the 1970s-1980s may also show premature wear. If you are remodeling and adding bathrooms, upsizing supply lines prevents future pressure loss.
How long does a typical copper line upgrade take, and will I be without water the whole time?
Most single-family homes in Maynardville can be fully repiped in two to four days. We stage the work so you have at least one functioning bathroom at the end of each day. Total water shut-off normally lasts 4-6 hours while we tie new copper into the main and pressure-test the system. Larger properties or extensive slab work can add an extra day.
Do I need a plumbing permit for pipe upgrades in Maynardville, and who handles it?
Yes. Union County and the City of Maynardville require a plumbing permit and inspection for any whole-house repipe or line relocation. Our licensed master plumbers pull the permit on your behalf, schedule the inspection, and provide you with all final documentation for your records and future resale disclosures.
Which grade of copper—Type K, L, or M—do you use for residential plumbing upgrades?
For interior potable water lines we install Type L copper, the industry standard for long service life and high pressure capacity without the extra cost of the thicker Type K (typically reserved for underground lines). Type M is thinner, less expensive, and legal in Tennessee, but we avoid it because it is more prone to pin-hole leaks over time and offers a shorter warranty.
What is the typical cost and warranty for a whole-house copper repipe in Maynardville?
Prices vary with square footage, number of fixtures, and whether walls are open. As a general guide, a 2-bath 1,800 sq ft home runs $5,500–$8,000. Larger or multi-story homes with slab foundations can range $9,000–$12,000. Our quotes are firm, include drywall patching, and come with a transferable 25-year parts-and-labor warranty plus a one-year free follow-up inspection.
