FAQs
What are pinhole leaks and why are they common in Cookeville plumbing systems?
Pinhole leaks are tiny perforations that develop in metal piping, most often copper. In the Cookeville area, our moderately hard water, higher‐than-average chlorine content, and natural minerals accelerate a chemical reaction called pitting corrosion. Over time, the inside wall of the pipe thins until a microscopic “pinhole” forms and begins to seep. Even a leak the size of a sewing needle can release gallons of water per day and lead to hidden mold, drywall damage, and structural rot if not addressed quickly.
How can I tell if I have pinhole leaks in my Cookeville home?
Warning signs include: (1) unexplained increases in your water bill, (2) damp spots or bubbling paint on walls or ceilings, (3) the sound of running water when fixtures are off, (4) blue-green stains or mineral crust on exposed copper pipes, and (5) lower water pressure at faucets. Because many Cookeville homes have pipes run through crawlspaces and interior walls, leaks can remain hidden for months. If you notice any of these issues, schedule a leak detection visit before damage escalates.
What piping materials do you recommend when upgrading to prevent future leaks?
For most Cookeville residences we install cross-linked polyethylene (PEX) tubing. PEX is flexible, resists scale buildup, will not corrode, and can expand slightly if frozen—ideal for the Upper Cumberland’s winter swings. Where code or homeowner preference calls for rigid pipe, we use Type L copper, which has a thicker wall than older Type M lines and is more resistant to pitting. CPVC is another option, but PEX’s speed of installation, longevity, and quiet operation make it the current gold standard for repipes in our region.
What does a whole-house pipe upgrade involve and how long will it take?
1. Inspection & planning: We map your existing system, review fixture locations, and pull the required Cookeville Building Department permit. 2. Rough-in: Water is shut off, old piping is drained, and strategic access holes are made in walls, ceilings, or the crawlspace. 3. Repiping: New PEX (or chosen material) is run from a central manifold to each fixture. 4. Pressure test & inspection: The system is pressurized to 150 psi and the city inspector signs off. 5. Restoration: We patch drywall, texture, and clean up. A 1,500 sq ft single-story home typically takes 1–2 days; larger or multistory houses may require 3–4 days. During most of the work we can restore evening water service so you’re never without water overnight.
Will a pipe upgrade damage my walls and floors?
We use minimally invasive techniques. Flexible PEX allows us to fish lines through attics, crawlspaces, and existing chases, so only small, targeted holes (about 4" × 4") are needed for branching. Flooring is rarely disturbed. After inspection, our crew patches, textures, and repaints to a paint-ready finish. We also lay protective drop cloths, use HEPA vacuums, and haul away old piping so your home is left clean and tidy.
Are there local codes or incentives I should know about before upgrading?
Yes. Cookeville follows the 2018 International Residential Code and the 2018 International Plumbing Code with Tennessee amendments. A plumbing permit and final inspection are required for any whole-house repipe. If you are replacing galvanized or polybutylene lines, some insurance carriers offer premium discounts—check with your agent. While the City of Cookeville does not currently provide rebates, Tennessee’s statewide Efficient Plumbing Standard may qualify certain low-flow fixture upgrades (often installed during a repipe) for tax-free purchasing during annual sales-tax holidays.
