Quick answers
- Drink/cook per utility guidance (boil or bottled) until the advisory is lifted.
- Skip ice makers and refrigerator water until lines are flushed per utility advice.
- Do not claim the municipal water is “always unsafe” — respond to the actual notice.
- Private wells after floods are a separate testing path (health department).
When to use this guide
When your water utility issues a boil-water notice, or when you are flushing the house after an advisory is lifted.
Definition
Advisories are utility-driven public health notices. Plumbing contractors help with filters, fixtures, and post-advisory flushing — not with declaring water safe.
When to act inside the home
During the advisory: avoid ice/dispensers, consider bypassing filters that can harbor contamination, and keep pets/kids from untreated tap water per utility guidance. After lift: flush cold taps, run ice makers to discard ice, and replace filter cartridges if the utility recommends it.
Failure modes
Using the ice maker the whole time, then serving that ice after the advisory ends. Or ignoring a well that took floodwater — wells need testing, not vibes.
Action
Bookmark your utility’s alert page. If you need help with filtration, softener bypass, or post-advisory fixture issues, request service. For leak waste during drought messaging, see the leak-fix act page.
Failure modes to avoid
Trusting social media over the utility notice
Start and end times matter. Use the official utility channel.

FAQs
Can you tell me if my water is safe?
Only your utility (or a lab for private wells) can clear an advisory. We help with plumbing steps around the notice.
Do filters make boiling unnecessary?
Not unless the utility or filter manufacturer explicitly says so for that contaminant. Many refrigerator filters are not a boil-water substitute.
