Slab leak repiping: what to know in Arizona
A single repair deals with one leak. If the surrounding pipe is worn, further leaks tend to follow, and each one means another detection and another opening.
Replacing the system removes that cycle, at a larger up-front cost.

Many Valley homes still have their original copper. In hard water and heat, wear accumulates, and leaks cluster as the line ages.
Repiping can be done in full or in stages, such as replacing only the runs that are leaking.
How it is done
New lines are run, usually through walls and the attic, to every fixture. Old lines are abandoned in place. Water is off for part of the work and the technician plans around that.
Drywall patching and paint are separate trades.
What a leak detection technician does
The technician looks at the leak history and the condition of the pipe. A full or partial repipe is proposed with a price and timeline.
You decide whether to repair, partially repipe or repipe fully.
Earlier leaks, where they were and what was done, help the technician plan.
Meter Still Moving? Talk to a Leak TechPartial repiping versus the whole house
Repiping does not have to mean the whole house. A technician can replace the runs that have failed and leave sound ones in place, or replace everything in one job.
What steers the choice is how many leaks there have been, where they were, how the rest of the pipe looks and how the home is laid out.
A full job takes longer and has a larger up-front cost, and it removes the pipe that is most likely to fail next.
A partial job costs less up front and may be followed by more work later. The technician lays out both.
When repiping comes up
Repiping is usually discussed after a line has failed in several places, or when leaks keep appearing in different parts of the same system. It replaces the run, or several runs, with new line on a new route.
One leak does not mean a house needs repiping. The technician looks at the number of leaks, where they were and what testing shows about the rest of the system before raising it.
Some homeowners ask about repiping after a single leak because they want to stop worrying about the next one. That is a fair question, and the technician explains what the tests show and what the trade-offs are.
Nothing is decided on the day unless you want it to be. A repipe is a bigger job, and you can take time to think.
What the work looks like
Most repipes route new line through walls and the attic rather than under the slab. Openings are made where the line enters each room and at the fixtures. The old slab lines are capped and left in place.
Water is off to parts of the house for periods during the work. The crew plans the order so the household is without water for as short a time as possible, and tells you in advance.
Patching the openings is part of the plumbing work; finishing walls and ceilings to match is often handled by other trades. The technician explains what will be left for you to arrange.
When the new lines are in, each one is tested and the meter is read with everything off. You see the reading before the crew leaves.
Questions to ask before deciding
Ask which lines would be replaced and which would stay. A partial repipe of the worst runs is sometimes an option.
Ask where the new lines would go and where openings would be made. Knowing this helps you plan around furniture, cabinets and finishes.
Ask how long water would be off and how long the job would take overall.
Ask what the alternatives would look like for your house: another spot repair, a reroute of one run or lining where it suits. Comparing them side by side makes the choice clearer.
Living in the house during a repipe
Most families stay in the house during a repipe. Water is off for periods while lines are connected, and the crew plans the work so those periods are as short as possible.
Expect openings in walls and ceilings in several rooms. The crew protects floors and furniture where they work, but it helps to clear the areas near fixtures and along the planned route.
Dust is part of the job. Closing doors to rooms not being worked on helps.
The crew tells you each day what they plan to open and when water will be off.
When the new lines are in, each is tested and the meter read with everything off. You see the reading before the crew leaves.
Partial and whole-house repipes
A whole-house repipe replaces every supply line in the house. A partial repipe replaces only the lines that have leaked or are most at risk.
Partial repipes are often the hot side only, because hot-side leaks are common. Some homes need only one run replaced.
The technician explains what testing showed and which lines they suggest replacing.
A partial repipe is quicker and less disruptive than a whole-house one, but leaves the other lines as they are.
You weigh the options and decide.
Planning a repipe around daily life
A repipe touches most rooms with water: kitchen, bathrooms, laundry and the water heater area. Think about which rooms you can do without, and for how long, before the work is scheduled.
Some families plan a repipe around time away from home. Others stay and work around it. The crew can tell you which parts of the work will be most disruptive.
Pets need a quiet room away from open walls and noise. Children may need to be kept out of work areas.
If you work from home, ask when the noisiest parts will happen.
The crew tells you each day what to expect, and you see the test results at the end.
What a repipe does not change
A repipe replaces supply lines. It does not change drains, which carry waste water away and are a separate system. If you have had drain problems as well as supply leaks, mention both, but expect them to be treated separately.
It does not change fixtures. Taps, toilets, showers and appliances connect to the new lines, but the fixtures themselves stay as they are unless you choose otherwise.
It does not change the service line from the meter to the house. If that line has leaked, it is a separate repair.
And it does not finish walls and ceilings. Openings are patched as part of the plumbing work, while texture, paint and any tile around fixtures are usually handled by other trades. The technician tells you up front what will be left, so you can plan the restoration before the crew arrives rather than after.
Before agreeing to a repipe, it is reasonable to ask for the test results that led to the recommendation, and to ask what a more limited repair would look like. The technician explains both, so you can compare them with the full picture in front of you.
Tell the dispatcher the year the home was built and whether there is a pool.
Not Sure Where the Water’s Going? Call UsQuestions about repiping
Is repiping always the answer to repeat leaks?
No. A reroute or spot repair may be enough. It depends on the pipe.
How long does an Arizona slab leak job take?
Usually a few days for a whole house. The technician gives a time based on the house.
Do I need to move out?
Often not, but water is off for part of each day. Ask about the schedule when you book.
What materials are used?
Ask the technician. We do not recommend a brand here.
How long does repiping take?
The technician gives a time based on the house. Size, access and what is above the lines all matter.
Will I be without water?
For part of the work. The technician plans around it.
Will walls be opened?
Small openings are made and patched. Painting is separate.
Can it be done in stages?
Often yes. Ask the technician whether your layout allows it.
