Repiping replaces a home's water supply lines entirely rather than patching each leak as it happens. It's the right conversation once a home has had more than one unrelated leak, since that pattern is a real signal the whole line, not just one section, has reached the end of its service life.
This comes up most in South Scottsdale's mid-century homes, where original galvanized steel supply lines from the 1940s through the 1960s are old enough that internal corrosion is often widespread. It also shows up in older South Tempe and Guadalupe homes with original 1970s-90s copper that Tempe's hard water has been corroding for decades.
When Repiping Makes More Sense Than Repeated Repairs
Multiple Unrelated Leaks
A second or third leak in a different part of the same line is a sign of widespread corrosion, not bad luck.
Low Water Pressure Throughout
Corrosion narrowing pipe diameter across the whole system, not just one fixture, points to the line itself rather than a single fixture problem.
Discolored Water At Multiple Taps
Rust-colored water from more than one fixture suggests the supply line itself is corroding, not just one water heater or valve.
Original Galvanized Pipe
A home confirmed to still have original galvanized supply lines is a strong candidate regardless of whether it's leaking yet.
PEX vs. Copper for a Repipe
PEX Flexibility
PEX tubing snakes through existing wall cavities with less demolition than rigid copper, which often means a faster job with less patching.
Copper Durability
Copper has a long track record and is preferred in some applications, though it costs more and requires more invasive installation.
Hard Water Resistance
Both materials handle Tempe's hard water better than aging galvanized steel, which is the material actually failing in most repipe calls.
Code Compliance
Whichever material is used, the installation is done according to the City of Tempe's own adopted plumbing code, with permits and inspection.

Common Questions
More than one unrelated leak, low pressure throughout the house, or discolored water from multiple fixtures are all real signals the whole line is failing, not just one section.
Both handle Tempe's hard water far better than the original galvanized steel they're typically replacing. PEX is generally less expensive and less invasive to install; copper has a longer track record and is preferred in some specific applications.
It depends on the home's layout and the material chosen. PEX generally requires less opening than rigid copper, and we plan the route to minimize what needs to be patched afterward.
