Quick answer
Read in 4 minOne pinhole is a leak. Two pinholes in a year is a pattern. Three pinholes is a repipe conversation. When copper develops pinholes from inside out — usually water chemistry, velocity erosion, or age past 40-50 years — patching buys 6-18 months before the next one. For most Evansville and Vincennes homes built before 1985 with original copper, a PEX repipe in the $5,500-$12,000 range beats spending the same on serial repairs.
- 01 Spot repair: $250-$650 per leak; buys 6-18 months at best on systemic pinhole homes.
- 02 Whole-house PEX repipe: $5,500-$12,000 in a typical SW Indiana home; 50+ year life.
- 03 Three pinholes in 24 months = the pipe is failing, not unlucky.
- 04 Copper pinholes often start in horizontal runs where water sits and chloramines react.
- 05 PEX is code-approved in Indiana, freeze-tolerant, and won't pinhole.
Section 02
After the second or third pinhole
One leak is a fluke. Two is a coincidence. Three within 18-24 months is the pipe telling you something. This page is for the homeowner who has fixed one or two and is wondering whether to keep playing whack-a-mole.
Section 03
Buying or selling an older home
Pre-1985 Evansville and Vincennes homes often have original Type M copper with thinning walls. Pre-purchase, knowing the repipe cost matters. Pre-sale, deciding whether to repipe (faster sale) or disclose (price hit) is real money.
Section 04
After insurance has paid one claim
Most insurers will pay for water damage from a sudden pipe failure once. After that, they often non-renew or exclude future water claims. If you've had one claim and the pipe is original, a repipe before the next leak is cheaper than the deductible plus premium increase.
Section 05
When water pressure or quality has changed
If supply pressure regulator has been recently adjusted, or the municipal water source/treatment has changed (chloramines vs chlorine), copper failure rates change too. Hidden cause behind suddenly leaky pipes you've had for decades.
Compare your options
The choice, honestly compared.
Option A: Spot repair (point patch)
Right call when there's one isolated leak in a copper system that's otherwise sound, the home is under 30 years old, or the pipe in question is accessible (no drywall demo). Cost $250-$650 per leak depending on access. Fast (1-3 hours), low disruption, doesn't disturb finishes. Wrong call when it's the third leak in 2 years, when leaks are in different parts of the house, or when the pipe is in a wall and the patch costs more in drywall than the plumbing. Buys 6-18 months at best on systemic failure homes.
Option B: Section repipe (one bathroom, one wall)
Right call when failures are concentrated in one area (one bathroom, one wall) and the rest of the system looks healthy on visual and pressure inspection. Cost $1,800-$4,200 for a typical bathroom-only repipe in PEX. Less disruption than whole-house, addresses the failing run, leaves working copper alone. Wrong call when leaks are scattered across the house — sectioning just delays the inevitable whole-house repipe and you'll pay labor twice.
Option C: Whole-house PEX repipe with manifold
Right call after 3+ leaks in 24 months, when the home is past 40 years on original copper, or when you're already renovating and walls are open. Whole-house PEX with home-run manifold distribution runs $5,500-$12,000 in a typical SW Indiana home depending on size, slab vs crawl, and access. 50+ year life on PEX, individual shut-offs at the manifold (no whole-house turnoff for one sink), no pinholes ever. Wrong call only when the existing copper is genuinely healthy and you're being upsold. Lifespan: longer than the next homeowner.
Key terms in context
Vocabulary you'll see on a real estimate.
This guide is written for plumbing decisions in Southwest Indiana. It uses the same terminology you'll hear from techs, inspectors, and the permit office.
Failure mode 01
Patching the third leak in two years
When pipes are pinholing systemically, the next leak is coming — usually 4-9 months out, usually in a worse location (behind a wall, in a ceiling). Each patch costs as much as a small piece of the eventual repipe, plus the water damage.
Failure mode 02
Repiping with the wrong PEX
Not all PEX is equal. Type A (Uponor, Viega) is more durable; Type B is acceptable but stiffer; Type C is the cheapest and not what we recommend. Some contractors install Type C to win on price — the warranty doesn't lie.
Proof, process & local validation
- 01 We won't recommend a repipe on a single isolated leak — that's our standard.
- 02 Every repipe quote shows the manifold location, PEX type, and shut-off plan in writing.
- 03 Licensed Indiana plumbers; permits pulled, inspections passed, you keep the paperwork.
How we build this guidance
- Licensed plumbers with 100+ documented Indiana repipes; we'll show photos from comparable jobs.
- We use Uponor or Viega PEX with manifold-style distribution — same systems we'd put in our own homes.
- Pat won't quote a repipe on a single isolated leak — that's our standard.
Methodology · Repipe recommendations follow Indiana plumbing code, manufacturer PEX certification, and documented leak history — no recommendation without a written failure log.

Common questions
Questions, answered.
01 Is PEX as good as copper?
For supply lines, yes — and in our hard water it's actually better. PEX doesn't react with chloramines, doesn't pinhole, handles a partial freeze without bursting (expands), and lasts 50+ years. Copper still has a place on visible runs and short connections, but for in-wall supply, PEX is the modern standard.
02 Will a repipe destroy my walls?
Some drywall has to come out — typically chases in the basement ceiling and small access cuts at each fixture. A typical 3-bath home repipe requires 8-15 drywall cuts that we cover with our drywall sub. Most homes are back to fully finished in 1-2 weeks; the plumbing itself is usually 2-4 days.
03 Can you repipe without tearing out walls?
Sometimes — slab homes with crawlspace access can often be done from below with minimal interior demo. Second-story bathrooms above finished spaces always require some demo. We map the route before you sign and tell you exactly how many cuts to expect.
04 Does homeowner's insurance cover pinhole damage?
Sudden pipe failures are typically covered for water damage cleanup and repair — but the pipe itself usually isn't. Repeated claims often trigger non-renewal. We document leak history for claims when needed, but we don't guarantee any specific coverage outcome — that's between you and your carrier.
05 How long does a repipe take?
Whole-house: 2-4 days of plumbing work plus 3-7 days of drywall and paint. We stage so water is off only during the active connection phase, usually 4-8 hours per day. You stay in the house — we work around showers and morning routines.
