My Copper Pipes Keep Getting Pinhole Leaks (Lofall, WA)

What usually causes pinhole leaks in copper in Lofall

Start with water chemistry. Slightly aggressive water dissolves copper from the inside over decades. Around Port Gamble and Highway 3 the housing dates from 1970s-to-2000s acreage homes and small farms, which makes this the likeliest answer to pinhole leaks in copper.

Then velocity erosion. Undersized hot lines or a recirculation pump wear the pipe at elbows and tees. We've seen it near Highway 3 more than once, usually on galvanized on canal-side cabins.

And contact corrosion: copper against concrete, fill, a steel hanger or a nail plate corrodes at the contact point. Less common on acreage along Lofall Road, but we've found it near the Hood Canal Bridge.

First steps on a Lofall property

Waterfront cabin lines are galvanized and copper transitions.

First steps for pinhole leaks in copper near Vinland: look at exposed copper in the crawlspace for green-blue staining or earlier patches. Count the pinhole repairs the house has had and where. Note whether the pinholes are all on the hot side. Then call; the rest is a locate through roots and till along Pioneer Way, not guesswork.

How we fix it

When it's the buried line, the fix in Lofall is whole-house repipe: we close and document, plan the openings through bluff clay on the Hood Canal shore at the marked spot on small farms off Pioneer Way, and tie in and test. New main shutoff and and the mini excavator ride on the first trip so it's finished the same visit.

the Hood Canal Bridge, Vinland, Pioneer Way: near any of them, pinhole leaks in copper gets the same crew and the same equipment. About half an hour north of Poulsbo, day or night, with the mini excavator on the trailer for parcels along Highway 3.
