Pinhole leaks in copper in Indianola, WA

The likely causes here

In Indianola we check contact corrosion before anything else, because pressure dropping on a shared line is how it shows up here. Copper against concrete, fill, a steel hanger or a nail plate corrodes at the contact point. A sandy beach shelf below the village makes the signs misleading, so we confirm rather than assume.

Next: water chemistry. Slightly aggressive water dissolves copper from the inside over decades. With till on the Indianola Road parcels under narrow village lanes near the dock, the symptoms can look identical to the first cause, which is why the meter test and the locate matter.

Finally, age. Copper from the 1960s and 70s has been in service for half a century, and thin spots fail first. Worth five minutes before anyone digs bluff clay above Port Madison.

What to check first

On the wooded parcels along Indianola Road and Miller Bay Road it's longer poly runs and the mini excavator.

Do this before anyone digs bluff clay above Port Madison in Indianola: count the pinhole repairs the house has had and where. Look at exposed copper in the crawlspace for green-blue staining or earlier patches. It takes minutes and it tells us whether the problem is on shared lines with no drawings or inside the house.

The fix in Indianola

The repair side is whole-house repipe. On wooded parcels along Miller Bay Road that means survey, then tie in and test in ground that holds water all winter where the problem actually is, then abandon or remove old lines. If what we expose is lines run across neighbors on easements at the end of its life, we say so with the pipe in your hand.

From Kitsap Memorial to the Country Store and out around Port Madison, pinhole leaks in copper is a regular Indianola call for us. About half an hour off Miller Bay Road, and emergencies on narrow village lanes near the dock dispatch immediately, any hour.
