About this example
Everything on this page is hypothetical, created to illustrate a common pattern. No real home, family or contractor is described.
Imagine new owners of an older two-story house. Each morning the first water from the bathroom tap is tinted brown, and the upstairs shower has gone from adequate to a trickle. A previous owner updated the kitchen, so some pipe under the sink is copper, which makes the rest of the system easy to overlook.
How they investigated
Cleaned aerators
Flow improved slightly at sinks, but the upstairs shower did not change.
Looked at exposed pipe
At the water heater and a hose bib they found dull grey threaded pipe that a magnet stuck to.
Called a licensed plumber
The plumber confirmed galvanized supply lines with copper only in the remodeled kitchen.
Asked for options
They requested estimates for replacing all supply lines, including the vertical runs to the second floor.

Common questions
Is this a real job?
No. It is a hypothetical example written for this guide.
Why did cleaning aerators not fix the shower?
In this example the restriction was inside the pipe, which aerator cleaning does not reach.
Can partly updated homes keep the newer pipe?
Sometimes. Ask a plumber whether the newer sections are worth keeping.
