Repiping is the fix when the problem is not one leak but the pipe itself. Two Tempe situations lead here. The first is an older home, often in Maple-Ash and the other early neighborhoods, still running its original galvanized steel supply, where the pipe has corroded from the inside until the water runs brown and pinholes open faster than anyone can patch them. The second is a slab home where the copper cast into the concrete has started failing, and each spot repair only buys time before the next pinhole a few feet away.
In both cases, chasing individual leaks becomes throwing good money after bad. A repipe replaces the failing supply with fresh material, typically routed overhead in PEX, so the water leaves the corroding galvanized or the leak-prone slab run behind for good.
Galvanized steel, and why old Tempe homes run brown
Plenty of pre-1990 Tempe homes were plumbed in galvanized steel. The zinc coating dissolves over decades, the bare steel corrodes, and rust builds up inside the pipe, narrowing the bore, dropping pressure, and turning the water brown at the tap. Once one joint gives way, the rest are close behind, because the whole system aged together. When we see a galvanized burst, a repipe is usually the real conversation, because patching one joint on a corroded system is a losing game.
Rerouting slab copper overhead
For a slab home where the in-concrete copper is failing, a repipe reroutes the supply overhead, through the attic and down the walls in PEX, abandoning the slab runs entirely. It ends the cycle of opening concrete for one slab leak after another, which on this hard water is otherwise a recurring expense. PEX also tolerates the Valley's water chemistry and slab movement better than the old copper did, so the new system is genuinely more durable, not just newer.
| Situation | Repair keeps working? | Better answer |
|---|---|---|
| First pinhole, young copper | Yes, spot repair | Repair it |
| Repeated slab leaks, aging copper | No, they keep coming | Overhead reroute or repipe |
| Brown water, failing galvanized | No, whole system is corroding | Whole-house repipe |
| Low pressure from scaled galvanized | No, the pipe is the limit | Repipe |
Living in the house while it is repiped
A whole-house repipe sounds more disruptive than it usually is, and knowing how it goes makes the decision easier. An overhead PEX repipe is run through the attic and dropped to fixtures through targeted access points, not by opening every wall, so the drywall work is limited and planned. The water is shut off in stages rather than for the whole job, so the house is rarely without service for long, and we sequence the work room by room. Because the new lines run overhead rather than through the slab, the disruptive concrete work that a slab repair involves is avoided entirely. Most homeowners stay in the house throughout. Understanding that the job is organized and finite, not a house turned inside out for weeks, is often what turns an overdue repipe from a dreaded project into a scheduled one.
A repipe usually follows repeated slab leaks or a galvanized burst, and confident leak detection confirms the pattern first. Softening the new system's water with a softener keeps it in good shape. We repipe older homes across Tempe and the historic core.
Questions
Repiping questions
How do I know if I need a repipe or just a repair?
A single leak in otherwise sound pipe is a repair. Repeated leaks, brown or discoloured water, and steadily dropping pressure are signs the pipe itself is failing, and at that point repairs just move the problem down the line. We assess the pipe's material, age and failure history rather than fixing pinholes one at a time.
Why is my water brown in an older Tempe home?
Almost always corroding galvanized steel supply pipe. The zinc lining dissolves over decades and the steel rusts from the inside, discolouring the water and narrowing the pipe. Once galvanized reaches that stage, a repipe is the lasting fix, because the corrosion is throughout the system.
Do you have to tear open all my walls?
Less than you would think. An overhead PEX repipe is routed through the attic and down to fixtures with targeted access points, not by opening every wall. We plan the route to minimize the drywall work, and we handle it cleanly rather than leaving your house in pieces.
Is PEX better than copper on this water?
On Tempe's very hard, corrosive water and shifting slabs, PEX holds up well and is not prone to the pinhole corrosion that has been failing old copper and galvanized here. It is a sound, durable choice for a repipe, which is why we route most repipes overhead in PEX.
