What to do to prevent your water lines coming into the home from freezing this winter?

✅ 1. Insulate All Exposed Pipes

Especially:

• Pipes entering from outside

• Pipes in crawl spaces, garages, attics, basements, or exterior wallsUse foam pipe insulation, split-foam sleeves, or thicker rubber insulation for colder climates.

✅ 2. Add Heat Tape or Heat Cables

For areas that get very cold:

• Wrap heat tape around exposed sections of pipe

• Make sure the product is thermostatically controlledThis is one of the most effective ways to prevent freezing.

✅ 3. Seal Air Leaks Around Pipe Entry Points

Cold air can creep in around:

• Hose bibs

• Foundation penetrations

• Crawlspace ventsUse expanding foam or silicone caulk to keep cold drafts out.

✅ 4. Keep Water Moving During Extreme Cold

Flowing water freezes far slower than standing water:

• Let a slow trickle run from faucets served by vulnerable pipes

• Focus especially on faucets along exterior walls

✅ 5. Open Cabinet Doors Indoors

If the pipes come up through kitchen or bathroom cabinets:

• Open cabinet doors on freezing nights

• Allow warm room air to reach the plumbing

✅ 6. Set the Thermostat Consistently

Avoid dropping temps at night:

• Keep home at at least 55°F

• If you leave for vacation, keep heat ON (never off)

✅ 7. Disconnect and Winterize Outdoor Spigots

• Remove hoses

• Use insulated faucet covers

• If available, shut off the interior valve to the outdoor faucet and drain the line

✅ 8. Insulate or Heat the Crawlspace / Basement

If pipes run underneath:

• Add insulation to the crawlspace ceiling

• Use safe electric space heaters only if the area is enclosed and monitored

• Close crawlspace vents during winter months

✅ 9. Install a Frost-Proof Yard Hydrant or Frost-Free Hose Bibbs

These place the shut-off point farther inside the home, protecting the line from freezing.

❄️ If You Want Tucson-Specific Guidance

Even though freezes are rare in Tucson, they do happen (particularly in Oro Valley, Marana, Vail). If you'd like, I can give you a localized checklist based on Tucson’s freeze patterns.
