Do you really need a repipe?
Often, the honest answer is no. A single leak at a fitting or a failed valve is a repair, not a reason to replace every pipe in the house. We would rather fix what is broken and leave sound pipe alone.
Repiping becomes worth discussing when the pipe itself is the problem, because patching one spot only moves the failure down the line.
Signs the pipes themselves are wearing out
One of these alone may be explained. Several together point toward the pipe.
Pinhole leaks that keep coming back
A repair holds, and then another small leak appears a few feet away. That pattern suggests the pipe wall is thinning.
Rust-colored or brown water
Discolored water, especially at first use in the morning, can come from corroding steel pipe.
Weak flow at several fixtures
Buildup inside the pipe narrows the opening and lowers flow, even when the street pressure is fine.
Green or blue stains on fittings
Pitting and staining around copper joints can mean corrosion from the inside.
Galvanized pipe and the pipes behind the walls
Galvanized steel pipe has a zinc coating that wears away, and the steel then rusts from the inside. The pipe narrows, flow drops, and eventually the wall gives out. It is typically found in older construction, and many newer Marana homes use different materials, so we confirm what you have before recommending anything.
We do not guess a pipe material from the neighborhood. We look where the pipe enters the house and wherever it is exposed in the attic or garage.

What Marana water and construction add to the picture
The Town's May 2026 table shows hardness from roughly 3 to 14 grains per gallon depending on the neighborhood. Harder water leaves more scale, which narrows pipe and wears valves. Your water bill or the Town lookup shows which system serves you.
Most newer Marana homes are built on concrete slabs, so supply lines often run in or under the slab or through the attic. When lines run under a slab, a repipe may reroute them overhead, the same idea behind slab leak repair by rerouting.
Whole-house repipe or a partial replacement
The scope should follow the condition of the pipe, not a sales target.
Partial repipe
- Replaces one failing run, such as the line to a bathroom or the section in the attic.
- Less access work, shorter water shutoff, and less repair of walls and paint.
- Leaves older pipe in place, so other sections can still fail later.
Whole-house repipe
- Replaces all supply lines from the main to every fixture.
- Ends the repeat-repair cycle on the old system.
- Needs more access openings in drywall and attic, and a longer period with the water off.
PEX or copper: the honest trade-offs
Both are accepted materials under the plumbing code Marana adopted. The right one depends on the house, the water, and your preferences.
| Question | PEX | Copper |
|---|---|---|
| How does it install? | Flexible tubing that bends around corners, with fewer joints | Rigid pipe joined with fittings, which takes more labor in tight spaces |
| How does it handle hard water? | Does not corrode from the inside, though scale can still coat fixtures | Can resist scale but may pit in some water, so conditions matter |
| How does it handle heat? | Must be protected from sunlight and follow manufacturer limits in hot attics | Handles heat well and is not affected by sunlight |
| How does it hold up to freezes? | Tolerates some expansion, but exposed runs still need protection | More likely to split if water freezes inside |
We explain which fits your house and why. There is no universal winner.
How a repipe project runs
Every house is different, but the sequence is usually the same.
- 1
Inspect and confirm
We check the existing pipe, test pressure, and look for leaks. If a hidden leak is suspected, we use leak detection first so we do not replace pipe that was fine.
- 2
Pull the permit
Marana lists plumbing permit and inspection through Development Services at (520) 382-2600. For Picture Rocks and other unincorporated areas, Pima County handles it, and our Picture Rocks page has the local detail.
- 3
Replace the lines
New pipe goes in, connections are made at fixtures and the water heater, and old pipe is capped or removed.
- 4
Test and close up
We pressure-test, restore water, and patch the access openings. Paint and texture matching are separate trades.
What to do before you call about repiping
- List the symptoms you see, such as discolored water, low pressure, or pinhole leaks, and where they happen.
- Take photos of any visible pipe, fittings and corrosion for the plumber.
- Ask whether your homeowner's insurance policy has any say in the repipe work.
- Plan for the water to be off for part of a day and store drinking water in advance.
Drywall, attic access, and how long the water is off
A whole-house repipe usually means a number of small openings in drywall and time in the attic. A partial job may need only one or two access points.
How long the water is off depends on the size of the house and the number of fixtures. We give you a plan for each stage, but we cannot promise a fixed duration before seeing the home. Repiping is permitted work under the 2024 International Plumbing Code (IPC) as adopted by the Town of Marana, so a written quote should say who pulls the permit and when inspections happen.
What drives the cost of repiping
Repiping is a project, so the price depends on the size of the home and the route, and we give you a clear price before work starts.
Frequently asked questions
Galvanized pipe is gray steel, usually threaded at the joints, and a magnet will stick to it. Copper is brown or green, and PEX is flexible and colored red, blue, or white. If you are unsure, we can identify it when we look at the pipe where it enters the house.
Probably not on age alone. Most newer homes have pipe that can last for decades. A repipe becomes a topic if a specific pipe material is failing, or if scale and leaks pile up. We check before recommending anything.
If the cause is buildup inside old pipe, a repipe can improve flow. If the cause is a regulator, a partly closed valve, or a utility-side problem, replacing the pipe will not help, so we find the cause first.
Ask first. Marana lists plumbing permits and inspections under Development Services at (520) 382-2600, and rules can vary by job. In unincorporated areas such as Picture Rocks, Pima County issues permits instead.
Usually not. If a pipe bursts or a leak is spreading, that is an emergency for our 24/7 line, and the repair comes first.
Not by itself. Hardness runs from roughly 3 to 14 grains per gallon by neighborhood, and treatment may address scale. Replace pipe only if it is actually failing.
