Plumbing in Anchorage fails in the crawl on a night the rooms still feel acceptable. Supply lines freeze there, and at hose bibs the inlet wind can reach. Shut the main if water is loose, and know which valve that is before you are standing in it. If the meter moves with the fixtures off, you still have a live leak. A fully heated house and a house left dark are different emergencies.
Sort ice-dam water, melt that found the crawl, and a split supply before anyone cuts a wall. They look alike on a ceiling and they are not alike. A cable will clear a clog and will not repair a belly or a vent plugged with frost. Frost heave can pull a shallow line at a step. Shut the exposed bibs from indoors while you still can.
The water heater has been running with the heat for months. It weeps at the base when nobody is looking at it. Name gas or electric, the pan, and the shutoff. If a flue smells wrong, stop using it. A tank that shifted in a shake should be named apart from any freeze. Do not pump crawl water into a drain that was never meant for it.
Use the short bright season for the exterior work: a line in an outside wall, a vent through the roof, a bib you can service in real daylight. If water is out of place tonight, that is the call, not the season. Crawl access in Anchorage is often tight and full of insulation. A stain that shows up after a thaw may be the roof, not a pipe.
Say leak, freeze, drain, or water heater, and where in Anchorage. Say if the main is already off and if the heat is on. Mention the crawl. Say if a shake moved the tank. A sagging ceiling is not a bucket you can postpone. Cold standing water is not going to wait. Call the number on this page.
