Plumbing conditions in Washington
Washington has mild, wet winters in the west and cold, dry winters in the east. Many crawl-space and basement homes in the wet west, where moisture and mold are common.
Hard freezes are infrequent in Washington, so many homes have pipes in attics, crawl spaces and exterior walls with little insulation. When a rare cold snap does arrive, burst pipes spike across the area within a day or two.
Washington generally has soft to moderately soft water. Scale is less of a problem, but soft, slightly acidic water can be harder on older copper pipes, which can develop pinhole leaks over time.
