Whole-Home Repiping

Whole-home repiping is the replacement of a house’s entire potable water supply system — every hot and cold run from the main entry to each fixture — ending the cycle of pinhole leaks, corrosion, and choked flow that aging pipe inflicts. When spot repairs have become a recurring line item, repiping replaces the system instead of nursing it.

How do you know your home is ready? The pattern is unmistakable: pinhole leaks springing up in different places, rusty or discolored water from taps, water pressure dropping throughout the house (not just one fixture), and supply pipe old enough to have outlived its era — galvanized steel from the mid-century, copper showing pinhole corrosion, or polybutylene with its known failure history. If that describes your home, call (833) 834-1087 — we pressure-test, map the system, quote PEX and copper options with straight numbers, and most repipes finish within days with water restored each evening.

How a home’s supply system works — and why it fails

Your supply system is a pressurized tree: the main enters the house, runs as a trunk (or splits at a manifold into individual home runs), branches to each bathroom, kitchen, and laundry, and terminates at fixture stub-outs with shutoff valves. Every joint, elbow, and valve is a potential failure point, and pipe materials fail in characteristic ways that tell a trained eye exactly what era the plumbing came from.

Galvanized steel — the mid-century standard — fails from the inside out. The zinc coating eventually gives way, and the steel rusts, building up tuberculation: nodular rust-scale that narrows the bore until a half-inch pipe flows like a quarter-inch one. Pressure drops, water discolors, and the rusted threads at joints become the leak points. Copper fails differently: pitting corrosion eats tiny pits through the wall, especially in aggressive or mineral-heavy water, producing the infamous pinhole leak — a fine jet of water inside a wall that soaks insulation and drywall for weeks before anyone notices. One pinhole is a repair; the third is a system telling you it is done. Polybutylene, installed widely for a period in the late last century, became known for widespread fitting and pipe failures, and its presence alone is reason to plan a repipe. Even well-installed pipe has a service life, and houses outlive their plumbing.

Repiping materials: PEX versus copper

The central choice in every repipe, and both materials are excellent when installed correctly. Here is the honest comparison.

PEX (cross-linked polyethylene)

Flexible plastic tubing that has become the dominant repipe material for good reasons. It arrives in long coils, so runs go from manifold to fixture with far fewer joints — and joints are where leaks start. It resists mineral scale buildup on its smooth interior, tolerates freezing better than rigid pipe (it can expand slightly rather than splitting), will not corrode or develop pinholes, and costs less in both material and labor. Connections use expansion fittings (PEX-A) or crimp/clamp rings (PEX-A and B), both reliable when done with proper tools. Its limits are real: it cannot be exposed to sunlight (UV degrades it), so it stays inside walls and attics; and some homeowners simply prefer the feel of metal pipe. For most homes, it is the practical, economical, long-lived choice.

Copper (types L and M)

The traditional premium material: rigid pipe joined by soldering or modern press-fit fittings, with a track record measured in generations. Copper is UV-stable, rodent-resistant, naturally rigid (which some installers prefer for straight runs), and time-proven in every climate. It costs more — material and the skilled labor to install it — and in aggressive water it can still develop the pinhole corrosion that condemns old copper systems. Press-fit connections have made copper repipes faster and flame-free. Homeowners who want the classic material and accept the premium get a system with nothing left to prove.

Layout: manifold versus trunk-and-branch

Material is half the decision; layout is the other. A manifold system runs individual home-run lines from a central manifold to each fixture — like a breaker panel for water — giving fast hot-water delivery, balanced pressure, and the ability to shut off one fixture without affecting the house. Trunk-and-branch mimics the original layout: a main trunk with tees branching to fixture groups. Manifold costs more in tubing but performs better; trunk-and-branch is simpler in tight retrofits. We recommend per house, not per habit.

Signs your home needs repiping

• Pinhole leaks appearing in different locations — the system’s signature failure.
• Rusty, brown, or discolored water from taps, especially after the water sits.
• Water pressure dropping throughout the house, not at one fixture.
• Visible corrosion, green staining, or flaking on exposed pipe.
• Supply pipe from the galvanized or polybutylene eras, still original.
• Repeated slab leaks or under-slab supply failures.
• Metallic taste in the water from corroding pipe.
• A repipe already done partially — mismatched old and new sections.

What whole-home repiping includes

• Full system assessment: pressure test, fixture count, pipe material and condition mapping.
• Complete replacement of hot and cold supply lines in PEX or copper — your choice, both quoted.
• New shutoff valves at every fixture and new supply stops.
• Manifold or trunk-and-branch layout designed for your floor plan.
• New main shutoff valve if the existing one is seized or failing.
• Drywall openings kept small, cut cleanly, and patched after inspection.
• Pressure testing of every new run before walls close.
• Permit handling and inspection coordination.
• Water heater reconnection and system re-pressurization.
• Final walkthrough: every fixture run, checked with you present.

What a repipe visit looks like

Step 1 — Assessment and quote. We map the existing system: pipe material and age, fixture and bathroom count, stories, attic and crawl access, and where the main enters. You get two honest quotes — PEX and copper — with the trade-offs explained, not steered.

Step 2 — Protection and access. Floors and furniture are protected. Small, strategic openings are cut at fixture walls and chases — repiping is far less destructive than its reputation, because new lines fish through the same cavities the old ones occupy.

Step 3 — The new system goes in. Old lines are abandoned or removed; new runs are pulled, secured, and connected with new valves throughout. Most homes take a few days, and water is restored each evening — you are never without water overnight.

Step 4 — Test before close. Every run is pressure-tested and every fixture is run. Only after the system proves tight do walls get patched.

Step 5 — Patch, clean, walk through. Openings are patched, the work area is cleaned, and we walk the whole job with you: every fixture, every valve, every shutoff — so you know your new system personally.

Protecting a new piping system

A repipe resets the clock — smart maintenance keeps it reset. The two great enemies of new pipe are excessive pressure and aggressive water. A pressure-reducing valve protects every joint and valve from the slow stress that shortens system life. Water treatment — a softener in hard-water homes — prevents the mineral scale and corrosion chemistry that aged the old system prematurely. Know where your new main shutoff is (we will show you), exercise fixture valves yearly so they never seize, and have the system checked if pressure changes or discoloration ever returns. New pipe, protected properly, should outlast your ownership of the home.

What affects the cost of a repipe

Size and layout dominate: square footage, number of stories, and bathroom and fixture count set the footage of pipe and number of connections. Access shapes labor — a single-story home with attic access repipes faster than a two-story slab home where every run must fish through finished walls. Material choice is the next fork: PEX or copper, quoted both ways so the decision is yours with real numbers. The scope of wall repair matters — small strategic openings versus extensive patching — as does the condition of related components: a seized main shutoff, corroded hose bibs, and an aging water heater connection are often addressed in the same project. Permits and inspections are part of honest pricing. What you get before we start is a flat-rate quote for the whole job — no per-opening surprises, no mid-project revisions.

Related plumbing services

Repiping decisions usually start with a symptom that belongs to another service. Recurring hidden leaks are confirmed by leak and slab detection — instruments pinpoint each leak and reveal whether you have one bad joint or a system-wide failure. A burst pipe that forces the question at midnight is handled first by emergency plumbing. Once the new system is in, water treatment protects it from the hard water that aged its predecessor, and a water heater check ensures the heater matches the new system’s flow and pressure. Each page covers its service in full.

Whole-home repiping FAQs

How do I know I need a full repipe instead of another repair?

The pattern decides: pinhole leaks in multiple locations, system-wide pressure loss, discolored water throughout the house, and pipe from an era known for failure. One leak is a repair; a system producing leaks on schedule is a repipe. Our assessment — pressure test plus condition mapping — gives you evidence, not a sales pitch.

PEX or copper — which should I choose?

Both are excellent. PEX costs less, installs with fewer joints, resists scale and pinholes, and tolerates freezing better. Copper is the time-proven premium material — rigid, UV-stable, with a generations-long track record — at a higher price. We quote both and explain the trade-offs for your specific house; the choice stays yours.

How disruptive is a whole-home repipe?

Far less than most homeowners fear. Work proceeds room by room with protection in place, openings are small and strategic, and water is restored each evening — most repipes complete within a few days. The mess is contained, the patching is clean, and the walkthrough at the end covers every fixture.

Will you have to tear out my walls?

No — repiping fishes new lines through existing wall cavities, attics, and chases. Openings are cut only where needed to make connections: small, clean, and patched afterward. Whole-wall demolition belongs to bad planning, not to repiping.

My home is on a slab. Can it still be repiped?

Yes — slab homes are repiped by rerouting overhead through walls and attics, abandoning the old under-slab lines in place. No concrete is broken. This is standard practice and often the right answer even where spot slab repairs are possible, since it removes the pipe from the hostile under-slab environment entirely.

What about polybutylene pipe?

Polybutylene, installed widely for a period in the late last century, became known for widespread failures of both pipe and fittings. Its presence is itself a reason to repipe — insurers know it, and so do we. If your home has it, plan the replacement on your schedule rather than waiting for its schedule.

Should I replace the water heater during a repipe?

Not automatically — but it is the economical moment if the heater is aging. The system is already depressurized, walls are already open, and the heater’s connections get renewed as part of the job. We assess its condition and give you a straight recommendation.

Will repiping improve my water pressure?

If low pressure comes from corroded, scale-choked pipe — the usual cause of system-wide pressure loss — then yes, dramatically: new full-bore pipe restores the flow the system was designed for. If pressure loss comes from the municipal supply or a failed regulator, we identify that during assessment instead.

Do I need a permit for a repipe?

In most Texas municipalities, yes — repiping is permitted work subject to inspection. We handle the permit and coordinate the inspection as part of the job. Permitted, inspected work also protects you at resale: unpermitted plumbing is a disclosure problem.

How long does a repipe take?

Most single-family homes complete within a few days, with water restored each evening. Larger homes, two-story layouts, and extensive fixture counts take longer — your quote includes a realistic timeline for your house, not a generic promise.
