Pinhole leaks arriving in a cluster
Copper of the same age, in the same water, fails on roughly the same schedule. The second pinhole in a year is the signal to stop patching and price the whole house.

The problem in one sentence
There is no attic, so the pipe has to go somewhere else
In a conventional house a repipe is a day in the attic and some drywall patches. Here there is no attic, no crawlspace, and the ceiling is a finished surface people chose the house for. That single fact drives the cost, the disruption and the sequence of the work.
Pressure that has dropped everywhere
Not one fixture, all of them. Usually corrosion narrowing the bore across the system, sometimes a failed regulator upstream. Measured before it is diagnosed.
Discoloured water on the first draw
Rust or green tint at the first tap of the morning, clearing after a few seconds. The pipe wall is giving up its inside surface.
A wall opened for something else
A bathroom coming out, a floor being replaced, a kitchen going in. This is the cheap moment to retire under-slab supply runs, and it is easy to miss.
Angle stops and valves that will not turn
Original stops seized in place under sinks and behind toilets. Minor on their own, but they are the reason a small repair becomes a whole-house shutoff.
The four routes
Where new supply pipe actually goes
Interior partitions are the first choice. Non-glazed walls that run the right direction can carry vertical pipe with drywall patched afterwards, and in these houses those walls are also where the plumbing already clusters.
Furred soffits are the second: a shallow boxed run at the ceiling line, usually along a corridor or a kitchen wall. It costs a few inches of headroom in one plane and it is the honest answer when there is no wall going the right way. Done well it reads as part of the house; done carelessly it reads as a mistake, so ask to see photographs of previous work.
Cabinetry and the utility core absorb a surprising amount of the run, behind kick spaces, up the back of a closet, through the wall the water heater already occupies. Cheap and invisible when the layout allows it.
An exterior wall route is last and sometimes unavoidable. It has to be insulated and detailed, and on a street-facing elevation it is the one option a local designation may have something to say about, worth checking with the City of Orange before it is drawn.
What you should not accept is a repipe quote with no route drawn. The route is the job.
Ask for the route in writing
Which walls open, how many ceiling patches, whether any soffit is added and where, who patches and paints, and what the finish will match. A repipe priced without those answers will be re-priced halfway through.
Timing it
The cheapest repipe is the one that shares a demolition
Because access is the expensive part here, the same repipe can cost meaningfully different amounts depending on when it happens. If a bathroom is being gutted, a floor lifted, a kitchen replaced, or a wall opened for anything at all, the pipe route through that area is already exposed.
Owners who plan well end up doing a repipe in two or three phases tied to other work rather than as one disruptive event, sequenced so no wall is opened twice. That needs a plumber willing to work to a plan rather than to a single visit, and it needs the plan to exist before the first wall opens.
The other thing worth doing at the same time is the small hardware: angle stops, supply lines, shutoffs, the pressure regulator. They are trivial while the system is already drained and irritating to schedule separately.
Radiant heating and the drainage side get their own pages. Fairhaven covers the warm-floor diagnosis, Fairmeadow covers drains, the atrium and the lateral.
Do this before any remodel
Get a plumber to walk the house before demolition is scheduled, not after. A ten-minute look at what is about to be opened is the difference between one repipe and two.

Two pinholes in a year is not bad luck.

Straight answers
Fairhills questions, answered
Can this house be repiped without cutting the slab?
Almost always, and that is the point. Under-slab supply runs are abandoned in place and new pipe is taken through walls, soffits or the utility core.
The concrete stays intact. The work moves from the floor to the walls and the ceiling line, which is where the planning goes.
Where will the new pipe actually run in my house?
Some combination of interior partitions, a furred soffit at the ceiling line, cabinetry and the utility core, with an exterior wall route as a last resort.
Which combination depends on your plan, where the glass is, which walls run the right direction, and where the wet rooms sit. It should be walked and drawn before it is priced.
Will I end up with a boxed-in soffit across the ceiling?
Sometimes a shallow soffit is the only honest route, and in a house with an exposed ceiling plane that is a real aesthetic decision rather than a detail.
Ask where it would go, how deep, and to see photographs of soffits the plumber has built in similar houses. If the answer is vague, keep asking.
Copper or PEX?
Both are used in these houses. PEX flexes around framing and needs fewer openings to thread, which matters a great deal when access is the expensive part. Copper is rigid and takes more openings to install.
The routing constraint usually decides it. Ask which the plumber prefers here and why, a reasoned answer either way is a good sign.
How long does a repipe take and can we stay?
A whole-house repipe is typically a matter of days rather than weeks, with water off during working hours and restored at the end of each day where possible.
Most people stay. Ask specifically about the water-off schedule and which rooms are unusable on which days, then plan around it.
Who patches the ceiling and walls afterwards?
Ask, and get it in the quote. Some quotes include patching to a paint-ready state, some include paint, and some leave open drywall for your own finisher.
In a house with a finished ceiling plane this is not a minor line item, so it should never be left implied.
We are remodelling a bathroom. Should we repipe now?
Very likely yes, or at least the section the remodel exposes. Access is the expensive part of every repipe here, and a demolition you are already paying for is free access.
Get a plumber to walk the house before demolition is booked so the route can follow the work rather than fight it.
Does a historic designation affect a repipe?
Interior and under-slab work is interior work. Designation, where it applies, concerns exterior character.
The one place it can matter is an exterior wall route or visible equipment on a street-facing elevation, worth confirming with the City of Orange before that route is chosen. We do not obtain approvals for you.
Who performs the work?
An independent local plumbing professional. Orange CA Plumbing Line is a referral service, not a plumbing contractor.
They diagnose, quote, perform the work and set out their own workmanship terms with you. Nothing is billed through us.
Tell us the symptom and whether anything is being remodelled. Those two answers set the plan.
