Repair a pipe when the failure is isolated and the rest of the system is sound. Repipe when leaks repeat in different locations, when the material itself is failing — galvanized steel, polybutylene, thinning copper — or when pressure and water quality problems trace back to the piping rather than a single fixture.
Nobody plans a repipe. It arrives as a third leak in eighteen months, or as a plumber saying the words "I can fix this one, but" while looking at the rest of the line. The decision is easier if you know what you are looking at.
One leak is a repair; a pattern is a system
Pipes fail for two very different reasons. Something happened to one spot — a nail, a freeze, a bad solder joint, a fitting that was stressed during a remodel — or the material itself has reached the end of its service life everywhere at once.
The tell is location. Leaks clustered at one fixture or one run are a repair. Leaks appearing in the crawlspace, then an upstairs bathroom wall, then the garage are not three coincidences. Pinhole leaks in copper are the classic version: the first one is unlucky, the third one means the pipe wall across the whole system is thin.
Pay attention to the water, too. Rusty discoloration on first draw, pressure that has quietly fallen off over years, or flow that is fine at one fixture and poor at another all suggest the pipe interior is the problem. Our leak detection work often finds the second and third problem before they surface.
What is behind the walls in older Colorado Springs homes
Neighborhoods like Old Colorado City, the Westside and parts of downtown have original supply and drain lines still in service.
- Galvanized steel supply. Zinc-coated steel that corrodes from the inside out. The failure mode is gradual restriction — the pipe silts up with corrosion until the shower runs thin — followed by leaks at threaded joints. Flow problems in a galvanized house are rarely fixable one pipe at a time.
- Cast iron drains. Durable for decades, then scaling and channel rot along the bottom of horizontal runs. A video pipe inspection shows the condition without guessing.
- Polybutylene supply. Gray or blue plastic from a specific era, with a history of fitting failures. Finding it is usually reason enough to plan replacement.
- Early copper with high pressure. Copper lasts a long time, but aggressive water, high velocity and high static pressure thin it faster. Some Colorado Springs pressure zones run high enough that a pressure-reducing valve is part of the real fix.
PEX versus copper and the rest
| Material | Typical use | Strengths | Watch-outs |
|---|---|---|---|
| Copper, type L | Supply lines, exposed runs, manifolds | Rigid, long service life, tolerates heat, recyclable | More labor and joints; vulnerable to aggressive water and high pressure |
| Copper, type M | Interior supply where permitted | Lighter and less costly to install than type L | Thinner wall — less margin where water is aggressive |
| PEX-A | Whole-home repipes, home-run manifold layouts | Flexible, fewer fittings, expands rather than splitting on freeze | Degrades with UV; must be protected from sunlight and rodents |
| PEX-B | Branch-and-tee repipes, remodels | Stiffer and economical; widely available fittings | Insert fittings slightly reduce inside diameter |
| CPVC | Some retrofit supply work | Inexpensive, handles hot water, no soldering | Becomes brittle with age; solvent joints are unforgiving |
Neither PEX nor copper is the right answer everywhere. PEX is faster to install through finished walls, needs fewer joints and handles a freeze better, which matters for pipe in unconditioned crawlspaces during our hard temperature swings. Copper is the choice for exposed mechanical-room runs and for homeowners who simply prefer it. A good plumber will use both in one house where it makes sense.
What a repipe actually involves
A whole-home repipe replaces the supply piping between the main shutoff and every fixture. It is open-wall work, but not as brutal as people imagine.
Expect access holes cut at strategic points rather than wholesale demolition — typically near fixtures, at the tops of walls and in ceilings below upstairs baths. Water is off during working hours and back on each evening in most jobs. A typical single-family repipe runs a few days of plumbing, followed by drywall patching, texture and paint, which is often a separate trade and a separate week.
Two things worth doing at the same time, because the walls are already open: adding shutoff valves where there were none, and installing or replacing a pressure-reducing valve if your pressure runs high. See piping and repiping for how the scope gets defined.
When repair is the right call
Repiping a house that does not need it is an expensive mistake. Repair, and keep your money, when:
- The leak has an obvious cause. A frozen hose bib line, a nail from a picture hanger, a fitting disturbed during a remodel — fix it and move on.
- The piping is copper, the house is not old, and this is the first failure. One event is not a trend.
- The problem is a fixture, not a pipe. Low flow at one faucet is usually an aerator or cartridge, and hard water here clogs both.
- Only one branch is galvanized. Partial replacement of a single original run is a legitimate middle path.
- You are selling soon and disclosure is honest. A documented repair with a real plumber's invoice beats a rushed partial repipe.
And if a slab leak is the issue, that is its own diagnostic path — see slab leak detection before assuming the whole system is implicated.
Questions to ask before you commit
- What material is in my walls, and how did you confirm it?
- What is my static water pressure, and do I need a pressure-reducing valve?
- Is this leak isolated, or have you seen the same failure elsewhere in the house?
- Does the quote include drywall repair, texture and paint, or just plumbing?
- How many days will water be off, and during what hours?
- Are new shutoff valves and accessible cleanouts part of the scope?
Frequently asked questions
How do I know if I need a whole-home repipe?
Repeated leaks in different parts of the house, rather than at one fixture, are the clearest sign. So are rusty first-draw water, pressure that has declined over years, and galvanized or polybutylene supply lines. A single leak with an obvious cause is a repair. A pattern across the system means the material itself is failing.
Is PEX better than copper for a repipe?
Neither is universally better. PEX installs faster through finished walls, uses fewer fittings and tolerates a freeze by expanding rather than splitting, which matters for pipe in unconditioned crawlspaces. Copper is rigid, long-lived and preferred for exposed mechanical-room runs. Many repipes use PEX in walls and copper where it is visible.
What causes pinhole leaks in copper pipes?
Pinhole leaks come from the pipe wall thinning from the inside, driven by water chemistry, high flow velocity and high static pressure. The first one can be isolated bad luck. When they start appearing in different rooms, the wall thickness is compromised throughout the system and repiping usually costs less than chasing each leak.
How long does a whole-home repipe take?
Most single-family repipes take a few days of plumbing work, with water shut off during working hours and restored each evening. Drywall patching, texture and paint follow and are often handled as a separate stage. Access holes are cut at strategic points near fixtures and wall tops rather than removing whole walls.
Are galvanized pipes a problem in older Colorado Springs homes?
Yes. Galvanized steel supply lines corrode from the inside, gradually restricting flow before they start leaking at threaded joints. Homes in older neighborhoods like the Westside and Old Colorado City often still have them. Because the restriction affects the entire system, replacing one section rarely restores pressure throughout the house.
