Galvanized Pipe Replacement
Galvanized pipe replacement removes old steel supply pipes whose zinc coating has worn away, leaving the steel to rust from the inside. Interior corrosion narrows the pipe, drops water pressure, and sends rust into your water. FlowFast connects you with an independent local plumber who will replace galvanized lines with modern piping.

Whole-Home RepipingFrequent leaks or rusty water? Signs your home needs repiping, copper vs. PEX, and how to get connected with an independent local plumber.
View all Repiping servicesGalvanized steel pipe was the standard for residential water lines for much of the twentieth century, and countless homes still have it. The zinc coating protected the steel at first, but over decades it wears away, and the pipe begins rusting from the inside out. The corrosion builds up like plaque in an artery: a pipe that started with a full interior diameter can shrink to a fraction of it, strangling water flow to every fixture downstream.
The telltale signs are unmistakable once you know them: rusty water when taps first open, steadily declining pressure over the years, and eventually pinhole leaks as the pipe wall thins. Unlike a single failed fitting, corroded galvanized pipe is a system-wide condition, so replacing it section by section rarely pays off. FlowFast connects you with an independent local plumber who will assess how far the corrosion has gone and replace the galvanized lines with modern PEX or copper.
Warning signs
Signs you need this service
- Water runs brown or rusty when first turned on, then gradually clears as the line flushes out.
- Water pressure has declined steadily over the years and is now weak at multiple fixtures throughout the home.
- You can see rust, flaking, or weeping at threaded joints on exposed pipes in the basement or crawl space.
- The home has original galvanized supply lines that are forty or more years old by now.
What to expect
The process, step by step
The pro inspects exposed piping and tests pressure to gauge how badly corrosion has narrowed the lines.
They plan replacement routes and help you choose between PEX and copper for the new system.
Old galvanized sections are cut out and new pipe is run to each fixture with proper supports.
The system is pressure-tested and flushed thoroughly until water runs clear at every tap in the house.
Prevention
How to avoid this problem
- Flush rarely used taps periodically so stagnant water never sits corroding the lines from the inside.
- Keep water pressure moderate, since high pressure accelerates wear on already-thin pipe walls and joints.
- Plan replacement before pinhole leaks start, because corroded pipe fails faster once leaking begins.
