PEX
- Flexible plastic tubing that does not corrode
- Fewer fittings and fewer wall openings
- Lower material cost: Angi lists $0.40 to $2 per linear foot
- Must be protected from sunlight and installed to the manufacturer's rules
Second pinhole leak this year? Low pressure from old galvanized pipe? A planned repipe ends the cycle of emergency repairs. We repipe in PEX or copper and handle the City permit.
A repipe replaces the water supply lines in a house, usually with PEX or copper, and is worth it when copper keeps developing pinhole leaks or galvanized pipe has choked water pressure. Most single-family repipes are done through small wall and ceiling openings that get patched afterward. In Newport Beach, a repipe needs a City plumbing permit. Call (949) 620-1945.
Repipe when leaks keep coming back, when the pipe itself is the problem, or when a remodel opens the walls anyway.
Newport Beach housing is older than many people assume. Census estimates show a median build year of 1978, with 46.5% of homes built between 1970 and 1999. Many houses on the Balboa Peninsula, in Corona del Mar and in Newport Heights are older still. That is a lot of original copper and some remaining galvanized pipe.
Both work well when installed correctly. PEX costs less and installs through fewer openings; copper is rigid, proven and preferred by some owners.
Angi puts the average whole-house repipe at about $7,500, with a range of $1,500 to $15,000. Size, number of bathrooms, stories, access and the material you choose drive the real price, and permit fees and drywall patching are part of a complete quote. You get a written, itemized price before work starts. More published figures are in our cost guide.
A well-planned repipe keeps the house livable and the water off for as little time as possible.
The plumber maps every fixture, the main shutoff, the water heater and the best routes through attic, walls and crawl space.
You approve an itemized price, including patching. The City plumbing permit is pulled.
Floors and furniture are covered and work areas are sealed off.
New supply lines go in through small, planned openings. Old lines are capped and abandoned in place where removal is not needed.
Fixtures and the water heater are connected, and the system is pressure tested.
The City inspects the work before walls are closed. Any structural member weakened by cutting or notching must be reinforced, repaired or replaced, and the water heater must be braced to state standard.
Openings are patched, and the work areas are cleaned.
The construction of the house changes how a repipe is routed.
Many 1960s and 1970s homes here have copper under or in the slab. A repipe usually reroutes everything overhead through the attic, which also ends the risk of future slab leaks.
Older beach cottages with crawl spaces allow lines to run under the floor. Sandy, damp crawl spaces near the harbor call for careful support and protection of the new pipe.
Some older homes still have galvanized steel or a mix of galvanized and copper from past repairs. Replacing the whole system restores pressure at every fixture.
Repipes in attached homes need HOA approval and coordination for shared walls and shutoffs. We work with boards and managers on scope and scheduling.
A repipe needs a City of Newport Beach plumbing permit and inspection.
California's SB 407 requires older, high-flow plumbing fixtures to be replaced with water-conserving ones when certain building permits are pulled. The City's SB 407 handout says the rule applies to building alterations or improvements to single-family homes, and the fixtures must comply before final approval. For multifamily and commercial buildings it applies to additions over 10 percent of floor area, alterations valued over $150,000, and permitted alterations to a room with noncompliant fixtures.
The City treats some permits as repair or maintenance that do not trigger the rule, including water heater replacement and sewer line replacement, plus "other repairs as determined by the Building Official." A repipe is not on that named list. So we confirm with the Building Division before the permit is filed and tell you plainly if fixture upgrades will be required. The compliant flow limits the City lists are 1.28 gallons per flush for toilets, 2.0 gallons per minute for a showerhead at 80 psi, and 1.5 gallons per minute for residential bathroom and kitchen faucets at 60 psi. See the Newport Beach plumbing permit guide.
Look at the pipes coming out of the top of your water heater or under a sink to see what your home is plumbed with.
| Material | What it looks like | What to know |
|---|---|---|
| Copper | Orange-brown metal, soldered joints; turns green or dark with age | Common in Newport Beach homes; older copper can develop pinhole leaks |
| Galvanized steel | Dull gray metal with threaded joints | Rusts inside over decades, cutting pressure and causing leaks at threads |
| PEX | Flexible plastic tubing, often red, blue or white | Common in modern repipes and newer homes |
| CPVC | Rigid cream or tan plastic with glued joints | Can turn brittle with age and heat |

Most families stay home during a repipe, with water back on at night on most single-family jobs.
Most pipe symptoms point to one of a few causes, and only some of them call for a full repipe.
| What you notice | Likely cause | Usual next step |
|---|---|---|
| A small spray or damp spot in a wall or ceiling | A pinhole leak in copper | Repair it once; plan a repipe if a second one appears |
| Brown or rusty water from hot and cold taps | Galvanized steel rusting from the inside | Replace the galvanized sections or repipe |
| Low pressure at every fixture | Galvanized buildup, a failing pressure reducing valve, or a partly closed main | Test the pressure and the regulator before deciding |
| Low pressure at one fixture | Scale in an aerator or cartridge, or a problem on one branch | Clean or repair that fixture or branch |
| A warm spot on the floor, or hot water slow to arrive | A hot water leak in or under the slab | Leak detection, then a reroute or repipe |
| Blue or green stains in sinks and tubs | Copper corrosion | Inspect exposed copper and watch for leaks |
| Banging or shaking pipes | High pressure, water hammer or loose pipe straps | Check pressure and secure the pipe |
One leak does not mean your whole system is failing. A pattern does. If the same kind of copper has leaked twice in a few years, the rest of it is the same age, in the same water, and usually headed the same way.
There are three honest answers to a leaking supply line, and the right one depends on how many leaks you have had and where the pipe runs.
We ask four questions before recommending any of the three. How many leaks have you had, and how far apart? What is the pipe, and how old is it? Where does it run: slab, crawl space, attic or walls? And how long do you plan to stay in the house? A family selling next spring and a family staying twenty years can reasonably make different calls on the same pipe.
The City reported no lead service lines in its system, so a repipe here is about the pipe inside your house, not a lead line at the street.
Under the EPA's Lead and Copper Rule Revisions, water systems had to finish a service line inventory by October 16, 2024. The City of Newport Beach Utilities Department reported that it verified 1,381 service lines as non-lead and found no lead or "galvanized requiring replacement" service lines in its distribution system. The City says it will keep recording material information and update the inventory as needed.
That inventory covers service lines, not the plumbing inside a home. Older houses in Corona del Mar, Newport Heights and on the Peninsula can still have galvanized steel supply pipe inside the walls, often mixed with copper from earlier repairs. Galvanized pipe rusts from the inside, which narrows the pipe, cuts pressure and sends rusty water to the tap. If you are served by IRWD or Mesa Water rather than the City, check that agency's own inventory notice.

Expect a real quote to reflect your number of bathrooms, the stories and the access, not the national midpoint. More published figures are in our plumbing cost guide.
The same repipe plays out differently depending on the street and the house.
Two units under one roof. The work has to be scheduled around tenants or summer bookings, and each unit should end up with its own accessible shutoff. Parking and alley access near the Balboa Fun Zone and Newport Pier shape the daily schedule in summer.
Low crawl spaces and a high water table near the harbor mean the new pipe needs solid support and protection off the soil. Small lots leave little room to stage materials, so deliveries are planned.
When a kitchen or bath remodel opens the walls, repiping at the same time saves a second round of openings and patching. Because a single-family alteration can trigger SB 407, fixture choices should be settled with the permit.
After a slab leak, many owners choose to reroute all supply lines overhead through the attic rather than repair under the floor again. Attic access and insulation affect the plan.
The HOA usually has to approve the work, and some shutoffs are shared. We coordinate the shutdown window with management so neighbors are not surprised.
Most repipe regrets come from what was left out of the job, not from the pipe chosen.
A repipe is the right time to check your home's water pressure and the pressure regulator, if you have one.
High static pressure is hard on pipes, fixtures and appliances, and a failing pressure reducing valve can cause banging pipes and dripping relief valves. A pressure reducing valve or check valve can make your plumbing a closed system, and the California Plumbing Code then requires an expansion tank or other approved device on a system with storage water heating. The plumber checks all of this as part of the repipe so the new pipe is not working against old problems.
A real person answers 24 hours a day. You get an honest arrival window and a written price before any work starts.
Repeat pinhole leaks in copper, a slab leak in older pipe, low pressure or rusty water from galvanized pipe, and visible corrosion are the main signs. If you have had two or more leaks in a few years, a repipe is usually the better long-term value.
Angi puts the average at about $7,500, with a range of $1,500 to $15,000. Home size, number of bathrooms, stories, access and pipe material drive the price. You get an itemized written quote, including patching and permit, before work starts.
Both are reliable when installed correctly. PEX does not corrode, costs less and needs fewer openings. Copper is rigid and long proven but costs more and can still develop pinhole leaks over time. We price both.
It depends on the home's size and layout. Many single-family repipes take a few days of work plus inspection and patching, and water can often be restored at the end of each day. You get a schedule with the quote.
Yes. A repipe needs a City of Newport Beach plumbing permit and an inspection before walls are closed. We pull the permit and meet the inspector.
It can depend on the project scope. The City lists some repair permits, such as water heater and sewer line replacement, that do not trigger it. We check before filing and tell you up front.
Yes. Condo and townhome repipes need HOA approval and coordination on shared walls and shutoffs. We work with boards and property managers on the scope and schedule.
Usually not. On most single-family repipes the work happens in sections during the day and the water can be turned back on at the end of each day. Ask for the daily schedule with your quote.
It should, and a complete quote says so. Leaving an old galvanized or copper section between the main shutoff and the new system keeps one of the weak points. Ask the contractor to list it.
The City of Newport Beach reported that it verified 1,381 service lines as non-lead and found no lead or galvanized requiring replacement service lines in its system, as part of the 2024 federal inventory. IRWD and Mesa Water customers should check their own agency's notice.
Angi lists about $300 for small drywall repairs and about $900 or more for larger projects. Ask whether your quote includes patching only, or patching with texture and paint.
Yes, in most homes. Old multi-turn shutoffs often seize or leak, and a new system with old valves still has weak points. Quarter-turn valves and new supply lines at each fixture are a sensible part of the job.
