Galvanized Pipe Homes in Grants Pass: Warning Signs You Need a Repipe
A lot of housing stock in Grants Pass predates 1990, and a fair number of those homes still have their original galvanized steel supply pipes. Galvanized pipe was standard for decades, but it corrodes from the inside over time, and unlike a leak you can see, that corrosion builds up quietly until it becomes a real problem.
Why Galvanized Pipe Fails
The zinc coating that protects galvanized steel wears away over 40 to 70 years, depending on water conditions. Once it’s gone, the steel underneath starts to rust and corrode from the inside, gradually narrowing the pipe and roughening the interior surface.
Signs Your Home May Be Affected
- Rusty or discolored water, especially noticeable first thing in the morning or after the water’s been off for a while.
- Falling water pressure over months or years, as corrosion narrows the pipe’s interior diameter.
- Pinhole leaks appearing in one spot, then another, a few months apart, a sign the whole system is aging out, not just one bad section.
- Visible pipe condition, if any galvanized pipe is exposed in a basement or crawlspace: flaking, dimpling, or a rough, pitted surface are red flags.
Repipe vs. Patch
Patching a single leak in a galvanized system is a short-term fix, if one section has corroded enough to leak, nearby sections are usually not far behind. A full or partial repipe (often done room by room to limit disruption) addresses the underlying issue instead of chasing leaks one at a time.
Not Sure What Pipe You Have?
If your Grants Pass home was built before the early 1990s and you haven’t had the plumbing updated, it’s worth having someone take a look, even without an active problem. Galvanized pipe is usually identifiable by a dull gray color and, unlike copper, it’s magnetic, a magnet that sticks to an exposed pipe is one quick clue.
Frequently Asked Question
Is copper or PEX better for a repipe? Both are common, code-compliant choices. PEX is often faster and less expensive to install since it’s flexible and needs fewer joints; copper has a longer track record and some homeowners prefer it for that reason. Either is a significant upgrade from galvanized.
