GuideHow to Winterize Outdoor Faucets in Bismarck
Outdoor faucets should be prepared before sustained freezing weather arrives. The most important step is to disconnect hoses and attachments so water is not trapped at the faucet. Where the plumbing includes a dedicated interior shutoff and drain, use that system as designed.
Disconnect Hoses and Attachments
Before freezing weather, remove garden hoses, splitters, timers, closed spray nozzles, and other attachments that can trap water. A connected hose can defeat the drain-down design of a frost-free faucet.
Inspect the Faucet
Look for dripping, damaged threads, a loose handle, visible cracking, or water that doesn’t stop. Repairing an existing leak before winter reduces uncertainty when temperatures fall.
Interior Shutoff and Drain
If your system has a dedicated interior valve: close the correct customer-operated valve, open the outdoor faucet, drain per the system design, and leave components positioned per instructions. Don’t close an unlabeled valve unless you know what it controls; don’t force a stuck valve.
Frost-Free Faucet Limits
A frost-free faucet places the shutoff farther inside the building, reducing freeze risk — but it still depends on correct installation, drainage, hose removal, and the interior section staying warm enough. “Frost-free” doesn’t mean immune to freeze damage.

Check Inside as Well as Outside
During mild weather, run the outdoor faucet while someone watches the accessible interior area. If water appears indoors, stop using the faucet and close a safe dedicated shutoff if one exists. See Faucet, Sink & Fixture Repair. For broader freeze damage, see Frozen & Burst Pipe Repair.
Add Outdoor Faucets to a Shutoff Map
Label verified customer-operated shutoffs and keep access clear — a property shutoff map is especially useful during winter emergencies. Don’t label a valve until its function is confirmed.
