Almost every home in Anchorage, Eagle River, and Wasilla is equipped with 'frost-free' Woodford or Prier sillcocks (outdoor hose bibs). A frost-free spigot works by placing the actual rubber shutoff washer 10 to 12 inches deep inside the heated rim joist of your house, allowing the outer copper barrel to drain dry every time you turn the handle off.
However, if a garden hose, pressure-washer adapter, or brass splitter is left screwed onto the outdoor threads during the first hard freeze in October, water cannot drain out of the barrel. The trapped column of water freezes solid, splitting the hidden copper barrel inside your wall or basement ceiling.
What To Do Right Now While Waiting for Dispatch
1. Disconnect Any Exterior Garden Hoses Immediately
Even on a 'frost-free' faucet, a connected hose traps water inside the copper stem barrel where sub-zero wind chill splits the copper inside the rim joist.
2. Listen for Hissing in the Rim Joist or Crawlspace
If the internal stem seat was damaged by ice expansion—or if someone turns the outdoor handle on—water sprays directly out of the split copper barrel into your floor joists, finished basement ceiling, or crawlspace.
3. Close the Dedicated Interior Sillcock Shutoff (Or Main Valve)
Follow the pipe straight inward from the outdoor faucet location inside your crawlspace, utility room, or basement drop ceiling to find the dedicated interior shutoff valve (or close your main house water shutoff).

Why We Install Interior Bleeder Ball Valves on Every Alaska Hose Bib
Even the best frost-free sillcock can freeze in a -30°F Wasilla or Hillside cold snap if cold air infiltrates the rim joist around the copper penetration. Whenever our plumbers replace a burst outdoor faucet, we install a dedicated quarter-turn brass ball valve with an integrated drain bleeder cap inside the warm mechanical space and foam-seal the rim joist penetration.
Questions & Answers — Emergency Guide #9 · Frost-Free Spigot Failures
Direct answers from our licensed Alaska emergency plumbing & flood recovery crew.
On a frost-free sillcock, the shutoff valve seat sits 12 inches inside the house, upstream of the split in the barrel. As long as the handle stays off, house water stops behind the split. The instant you open the handle, 60 PSI water rushes into the split barrel and floods the wall.
Yes. We replace burst sillcocks and install interior shutoff valves year-round across Anchorage and the Mat-Su Valley.
