Short freezes expose pipe routes built for milder weather
Richland Hills does not stay cold all winter, but a hard freeze still puts exposed plumbing under strain. Water freezes first in the pipe runs with the least protection: attics, garages, exterior walls, crawl-access areas, hose connections and unheated additions. As ice closes off a line, the faucets supplied by it lose water even when other fixtures in the house still run.
The trouble is not always visible while temperatures are lowest. A frozen pipe can hold together at first, then reveal a split when the weather warms and water reaches the damaged spot again. That is why thawing needs to be done carefully and followed by attention to the pipe route, not just the point where flow stopped.
The more built-up parts of Richland Hills include older homes and additions where plumbing routes are not always obvious. A remodeled room or changed-use space can leave a water line near an exterior surface, garage, attic, or other cold area without enough insulation around it. We use safe thawing methods rather than open flame or excessive concentrated heat, then consider the vulnerable section and the route around it so the next freeze is less likely to affect the same line.
