When this becomes an emergency

What a pro does

The first move is killing pressure at the main, because a plumber can't read anything useful while water's still driving through the break. Then comes the hunt. Most homes across the Treasure Valley sit on a vented crawlspace rather than a basement, and that crawlspace is where supply lines pick up trouble, since the vents that keep it dry in a Boise summer also feed outside air straight onto the pipes in January. Hose bibs and the stub-outs behind them fail more often than anything in the middle of the house. A high desert winter here doesn't sit steady either; a cold night followed by a mild afternoon flexes a marginal joint over and over. Once the plumber opens up the failed section, the damaged run gets cut back to sound pipe on both sides and rejoined with fittings that match the existing material. Copper, PEX and old galvanized all behave differently where they meet. The system gets brought back up under pressure and watched before anyone puts insulation or drywall back.

Frequently asked questions

Because the vents that keep moisture out of a crawlspace also let cold air in. On a still night in Boise or Nampa the temperature under the floor tracks the outdoor low fairly closely, and any supply line running near a vent or an exterior rim sits in that air with nothing but its own insulation between.
No, and that trips people up. Many Treasure Valley neighborhoods run pressurized irrigation from a separate untreated system alongside the drinking water service, with its own valves and its own seasonal drain-down. A break on one doesn't shut off with the other's valve.
That depends entirely on your policy and how the loss happened, so the answer has to come from your insurance provider. Photographing the wet area and the failed section before anything is torn out gives you something to work with when you do call them.
It tends to fail differently. Galvanized narrows with rust from the inside over decades, which raises pressure through the remaining opening and leaves less wall to survive a freeze. Older homes around Boise's original neighborhoods still have runs of it hiding behind plaster.
