How galvanized pipe repiping works
A whole-home repipe replaces the water supply lines, from where the water enters the house out to every sink, tub, shower, toilet, and appliance. Here is the whole job, from the first look to the final wall patch, in five stages. Select a step to see what happens at each one.
What a repipe actually is
Repiping is not a patch. It takes out the worn supply pipe, the galvanized steel, aging copper, or brittle plastic that rusts, leaks, and loses pressure, and runs a new system in new PEX or copper to every fixture. The drain and vent lines, which carry water away by gravity, are a separate system handled on their own.
Because old pipe rarely fails in just one spot, doing the supply side at once means one set of wall openings, one inspection, and one return to clean water and full pressure, rather than repeating the disruption in a year or two. A local contractor confirms whether a whole-home or partial repipe fits your home before any of this begins.
The five stages of a repipe
Inspection, planning, removal, installation, and testing. Select a stage to see what happens and watch the step play out.
A local contractor looks at the pipe material, the layout, and the access points, confirms whether a whole-home or partial repipe fits, and often runs a camera on the drains or the service line. This is where the plan starts and where surprises get found before the work does.
With the pipe known, the contractor maps the runs to every fixture and chooses where to open the fewest access points. You settle on the material, usually PEX or copper, the layout, and the schedule, including the short windows the water will be off.
Floors and belongings are covered, limited access points are opened, and the old corroded supply lines are taken out of the walls. The water stays on for as much of the job as possible, and only the failed system comes out, not the whole wall.
New PEX or copper is run to every sink, tub, shower, toilet, and appliance, supported at the right spacing and connected with the fittings code requires. This is the core of the repipe and the part that resets the system for decades.
The new lines are pressure-tested for leaks and inspected to local code before anything is closed up. Access holes are patched, the work area is cleaned, and you are back to clear water and full pressure, usually within a few working days.
What to expect during the work
How long it takes
Most single-family homes are repiped in a few working days, depending on size, the number of bathrooms, and how the pipe is routed.
Water and daily life
The water is kept on for as much of the job as possible and shut off only in short, planned windows, so most households stay in the home throughout.
Permits and code
In most areas a repipe is a permitted, inspected job. The new lines are checked against local code before the walls close, which protects you and keeps the work on record.
