PEX & Copper Repiping in Orange County

Full re-pipe of hot and cold water lines with modern, long-lasting materials.

When leaks keep coming back in different parts of the house, when water pressure has quietly dropped, or when your water comes out discolored, patching one section at a time is only postponing the next failure, and paying for it repeatedly.

ASL Plumbing repipes homes across Orange County with modern PEX or copper, replacing the failing supply lines throughout the property in a single planned project. A repipe trades a future of recurring emergency repairs for one predictable job that solves the root cause, and it is one of the most common improvements we do in the county's older neighborhoods.

When a repipe is the right call

Aging copper past its service life

In Orange County homes built from the mid-1980s through 2000, the original copper supply lines are now old enough that pinhole leaks begin to appear, accelerated by our hard water corroding the pipe from the inside. Once one pinhole shows up, more usually follow across the same aging run.

Galvanized steel pipe

The oldest OC housing, including many pre-1970s homes, was plumbed with galvanized steel that corrodes from the inside out. It gradually restricts flow, drops your pressure and can discolor your water with rust. Galvanized is well past its era and is a classic repipe candidate.

Polybutylene pipe

Some homes plumbed in roughly the late 1970s through mid-1990s used polybutylene, a gray plastic pipe prone to sudden failure. If your home has it, replacing it proactively is far better than discovering it through a burst line, and it is worth addressing at a home sale.

Recurring leaks and low pressure

When you are repairing leaks in multiple areas, or the whole house has lost pressure, the system is telling you the piping as a whole is failing. A repipe addresses the cause instead of chasing symptoms one leak at a time.

Slab leak reroutes

Rather than repeatedly opening the foundation for slab leaks on a failing line, we can repipe or reroute the affected runs above the slab, ending the cycle of slab repairs on that piping.

PEX vs copper: the honest comparison

PEX

Flexible cross-linked polyethylene tubing. It resists scale and freezing, needs fewer fittings, installs faster with less wall opening, and handles our hard water well. Often the most cost-effective modern choice, and increasingly the standard for residential repipes.

Copper

Rigid, time-proven and long-lasting, with a track record measured in decades. Some homeowners prefer it for its durability and familiarity. It costs more in material and labor than PEX and is more affected by hard-water corrosion over the very long term.

Which is right for you

The best choice depends on your home's layout, your budget, and your preferences. Both are major upgrades over aging original piping. We walk through the trade-offs during the estimate rather than defaulting to one.

Signs your home may need a repipe

  • Leaks appearing in more than one area of the home
  • Discolored, rusty or metallic-tasting water
  • A general drop in water pressure throughout the house
  • Frequent pinhole leaks in copper lines
  • Known galvanized or polybutylene piping
  • Water temperature that fluctuates when another fixture runs
  • A home built before 2000 with original supply lines

Why repiping beats endless spot repairs

When piping is failing throughout a home, each spot repair buys a little time before the next leak somewhere else, and the leaks you do not catch quickly cause water damage on top of the repair cost. A repipe ends that cycle. It also protects your home's value and your peace of mind: no more wondering which wall is next, no more emergency calls, and often better pressure and cleaner water immediately. For an older OC home, a planned repipe is usually cheaper over just a few years than the running total of individual repairs and the damage between them.

How our pex & copper repiping works

1
Assess and plan the route

We inspect your piping and map the repipe around your home's layout, fixtures and access points, so water delivery improves while wall opening stays controlled. You get a clear scope and a firm upfront price.

2
Install new PEX or copper

We install new supply lines throughout the property in your chosen material, pull the required permits, and keep the water off for as little time as possible during the work.

3
Test, inspect and restore

We pressure-test the new system, verify flow and every connection, close up the access points, and review the finished work with you. We guarantee the job.

What affects the cost of a repipe

Repipe cost depends mainly on the size and layout of your home (number of bathrooms, fixtures and stories), the material you choose (PEX is generally more economical than copper), the accessibility of the existing lines, and the amount of wall repair involved. Because these vary so much house to house, we assess your home in person and give you a firm written price and material options before any work begins. Estimates are free, and a repipe is often more cost-effective than people expect once weighed against repeated repairs.

PEX & Copper Repiping in Orange County

A whole-house repipe is one of the most common major jobs we do in Orange County's older neighborhoods, and for good reason: the combination of aging supply lines, very hard water and decades of use means the original piping across much of the county is at or past its service life. If you are buying an older OC home, it is worth asking about the pipes before you close rather than discovering the problem after move-in, and bundling a repipe with other work while walls are already open often saves on labor. Our crews handle repipes regularly across Lake Forest, Laguna Beach and South County.

Good to know

PEX & Copper Repiping FAQs

PEX or copper, which is better?+
Both are excellent modern options. Copper is rigid and time-proven; PEX is flexible, resists scale and freezing, installs faster with less wall opening, and is often more cost-effective. The right choice depends on your home's layout, your budget and your preferences, which we walk through during the estimate.
How long does a repipe take?+
Most whole-house repipes are completed in a matter of days, depending on the size and layout of the home. We plan the route to keep water shut off for as little time as possible, so daily disruption is limited.
Will you damage my walls?+
A repipe requires opening some access points to reach the lines, but we plan the route to minimize this and keep it controlled. We explain exactly what to expect, and where openings will be, before we start.
How do I know if I need a repipe instead of a repair?+
If you are getting recurring leaks in different areas, discolored water, or a general drop in pressure, those point to system-wide failure where a repipe is more cost-effective than repeated spot repairs. Known galvanized or polybutylene piping is also a strong reason. A camera and pressure check confirm it.
Do I have to repipe the whole house at once?+
Not always. If only certain runs are failing, a partial repipe or reroute may be enough. But when the piping is generally at end of life, doing it in one planned project is usually more cost-effective than repiping in pieces over time. We recommend based on what your system actually needs.
What is polybutylene and why replace it?+
Polybutylene is a gray plastic pipe used in some homes from the late 1970s through mid-1990s. It is prone to sudden failure, so replacing it proactively is far better than dealing with a burst line, and it is worth resolving at a home sale rather than after.
