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

What usually causes pinhole leaks in copper in Suquamish

The most common cause we find in Suquamish is water chemistry. Slightly aggressive water dissolves copper from the inside over decades. On parcels along Augusta Avenue with beach deposits near the dock underneath, that's where we look first.

We also check velocity erosion, because in Suquamish it explains a real share of pinhole leaks in copper calls. Undersized hot lines or a recirculation pump wear the pipe at elbows and tees.

And age: copper from the 1960s and 70s has been in service for half a century, and thin spots fail first. Less common on small village lots near Suquamish Way, but we've found it near the Suquamish Dock.

First steps on a Suquamish property

We coordinate the meter side with whichever utility serves the lot.

Before we arrive in Suquamish, three things you can do: look at exposed copper in the crawlspace for green-blue staining or earlier patches. Do the meter test to catch the current leak if there is one. Note whether the pinholes are all on the hot side. None of it requires tools, and all of it helps us tie in and test faster on small village lots near Suquamish Way.

How we fix it

Fixing pinhole leaks in copper here usually ends with whole-house repipe near the museum: tie in and test with manifold or trunk-and-branch fittings, close and document on waterfront lots on Agate Pass, run new lines. One crew, one visit, till under the village grid put back the way it was.

We've handled pinhole leaks in copper near the Suquamish Dock where the cause was poly along Totten Road, and near Augusta Avenue where hardpan on the uplands toward Indianola was hiding a drain failure. Twenty-five minutes via Highway 305; we schedule Suquamish so you aren't waiting a whole day.
