What’s different about outdoor plumbing in Boise
Canal-fed irrigation
Pressurized irrigation runs separately from drinking water and has its own shutdown schedule.
Backflow protection
Cross-connection devices protect city water and are vulnerable to freezing.
Frost-free hose bibs
Frost-free sillcocks help, but hoses must still be disconnected.
Homeowner checklist
- Blow out irrigation lines in fall
- Insulate or drain backflow assemblies
- Disconnect hoses
- Check for leaks at spring startup
Boise homes and when problems show up

Outdoor Plumbing & Hose Bibs in Boise: questions
How do I winterize pressurized irrigation in Boise?
After canal water is shut off, drain the system and blow out the lines with compressed air, then protect the backflow device.
Why did my hose bib leak in spring?
A frozen and split sillcock often leaks only once water is turned on; replacing it with a frost-free model helps.
Does Boise require backflow testing?
Requirements depend on your water provider and irrigation setup; check with your provider.
