As published by the Portland Water Bureau on Portland.gov in “How to prepare your plumbing for winter weather,” the city shares practical ways to reduce the risk of frozen or burst pipes when temperatures reach freezing.
Recommended steps include disconnecting hoses, insulating outdoor faucets and hose bibs, shutting off and draining outdoor lines if you have a separate valve, sealing gaps where pipes enter the building, closing foundation vents, and insulating pipes in unheated areas like attics, crawl spaces, and basements. When temperatures stay below freezing, it also recommends opening cabinet doors under sinks to let warm air reach pipes and letting faucets run a slight drip. Additional guidance includes checking irrigation and sprinkler systems, protecting backflow assemblies, and knowing how to shut off water quickly if a pipe freezes or bursts.
