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

What usually causes pinhole leaks in copper in Manchester

The most common cause we find in Manchester is velocity erosion. Undersized hot lines or a recirculation pump wear the pipe at elbows and tees. On Beach Drive lots sloping to the water with hardpan up Mile Hill underneath, that's where we look first.

We also check age, because in Manchester it explains a real share of pinhole leaks in copper calls. Copper from the 1960s and 70s has been in service for half a century, and thin spots fail first.

And water chemistry: slightly aggressive water dissolves copper from the inside over decades. Less common on rural parcels along Colby Road, but we've found it near Colby.

First steps on a Manchester property

Manchester Water District meters are at the road.

Before we arrive in Manchester, three things you can do: look at exposed copper in the crawlspace for green-blue staining or earlier patches. Note whether the pinholes are all on the hot side. Do the meter test to catch the current leak if there is one. None of it requires tools, and all of it helps us run new lines faster on rural parcels along Colby Road.

How we fix it

Fixing pinhole leaks in copper here usually ends with whole-house repipe near Colchester Drive: run new lines with pEX-A tubing, hot and, close and document on the village near the state park, abandon or remove old lines. One crew, one visit, clay seams and seeps on Beach Drive put back the way it was.

We've handled pinhole leaks in copper near Colby where the cause was 1940s galvanized on beach homes, and near the fuel depot where fill and beach deposits on Colchester Drive was hiding a drain failure. Down Mile Hill Drive from Port Orchard; we schedule Manchester so you aren't waiting a whole day.
