FAQs
What causes persistent pinhole leaks in Greeneville homes?
In Greeneville, the two biggest culprits are the town’s slightly acidic water (pH below 7) and aging copper or galvanized steel lines. Acidic or mineral-rich water slowly erodes the interior of metal pipes, creating tiny pits that eventually become pinhole leaks. High water pressure, improper grounding of electrical systems to plumbing, and the use of aggressive chemical drain cleaners can speed up the process.
How do I know it’s time to upgrade my pipes instead of repairing individual leaks?
If you’ve had two or more pinhole leaks within a 12-month period, see widespread corrosion on exposed piping, or notice rusty or bluish-green staining in sinks and tubs, your plumbing system is nearing the end of its service life. At that point, continued spot repairs usually cost more over time than a one-time pipe upgrade (repiping). A camera inspection and water quality test can confirm the overall condition and help you decide.
What pipe materials do you recommend for replacements in Greeneville?
For most homes, PEX-A or Type L copper are the go-to choices. • PEX-A: Flexible, resistant to scale and pitting, and unaffected by slightly acidic water. It installs quickly with fewer fittings, lowering labor costs. • Type L copper: More traditional, has a 50-year life expectancy when water chemistry is balanced, and is fire-resistant. We sleeve or coat the copper to protect it from local soil acidity when used under slabs. In well water applications with high iron or sulfur, CPVC is sometimes preferred.
How long does a whole-house repipe usually take?
A typical 2-bath, 3-bedroom home in Greeneville can be repiped in 2–4 days. Day 1 covers shut-off, site prep, and removal of old lines. Days 2–3 involve running new PEX or copper supply lines, pressure testing, and rough drywall patching. Water service is generally restored each evening so you’re rarely without water overnight. Larger homes or those with extensive drywall or slab work may take up to a week.
Will repiping damage my walls and floors?
We use minimally invasive techniques: small access holes are made near fixtures, in closets, or behind cabinets. For PEX retrofits, we often fish the tubing through existing wall cavities, reducing the need to open large sections of drywall. After the new system passes inspection, we patch, texture, and prime the openings. If pipes run under a concrete slab, we typically reroute them through the attic or walls rather than jackhammer the floor, preserving your flooring.
What does a pipe upgrade cost, and are financing options available?
Pricing depends on home size, pipe material, and accessibility, but most Greeneville repipes range from $3,500 to $9,000. Copper adds about 20–30 % to that total compared to PEX. We provide a free in-home estimate with a written, line-item quote. To make the project easier on your budget, we offer 0 % APR financing for 12 months or low-interest plans up to 60 months, subject to credit approval.
