Could I still have hidden Uri 2021 damage?

Yes â€” and it's surprisingly common in 2026. Many Uri-era Austin pipes took stress fractures that didn't fully burst but have been weeping into insulation since February 2021. Symptom: noticeable water bill creep with no usage change. A thermal scan (quick and non-invasive) finds them. Worth doing if your home was occupied during Uri AND you've noticed any bill creep.

What temperature do Austin pipes burst?

Depends on insulation + duration. Properly-insulated indoor pipe: fine to 10Â°F+ ambient for hours. Uninsulated attic supply: splits at 25Â°F sustained 6+ hours. Exterior hose bibs without frost-free: split at 28Â°F sustained 4+ hours. Uri (single-digit temps for 4+ days) blew through everything. First-freeze-of-season is the danger window most years.

Will foam pipe insulation prevent ALL freeze risk?

No â€” but it prevents 80%+ of attic + wall cavity freezes. Foam wrap raises interior pipe temp relative to outside ambient by 10-15Â°F. That's the difference between frozen and unfrozen in most Austin freeze events. Doesn't help with Uri-magnitude sustained sub-10Â°F (those require heat tape + interior drainage). For typical Austin winter cold snaps, foam wrap is sufficient.

How much foam insulation do I need?

Typical Austin 3-bedroom home: 30-50 linear feet of attic supply line + 8-15 feet of exterior wall cavity supply + 3-4 hose bibs. Foam insulation comes in 6-ft pre-slit tubes (inexpensive at any hardware store). Total: 6-10 tubes covers most homes as a low-cost weekend project. Or grab whatever the hardware store has on the discount end-cap before winter.

Should I drip my faucets during freeze warnings?

Yes â€” when NOAA forecasts overnight low under 28Â°F. Open every interior faucet (cold AND hot side) to a slow drip. Moving water resists freezing. Cost: pennies. Forecast-triggered, not all winter. For sub-15Â°F sustained (Uri-magnitude): drip isn't enough â€” shut off main + drain system.

Can the dispatched plumber install heat tape on exposed pipes?

Yes â€” heat tape (installed per linear foot of exposed pipe) is the right call for chronically-exposed pipes (well house, exterior wall locations, particularly cold attic runs). Self-regulating heat tape automatically turns on at near-freezing. The dispatched plumber installs + electrically connects. Worth it for homes with known freeze-vulnerable runs.

How do I prepare my house for winter vacation?

Drop thermostat to 55Â°F minimum (NOT OFF â€” interior pipes need to stay above freezing). Drip the faucet farthest from the water heater (slow drip on cold + hot). Have a neighbor check the house every 2-3 days. For trips longer than a week during peak freeze months: shut off the main + drain the system. Cost: a few minutes of your time. Cost of skipping it: a multi-day vacation-week burst and major water damage.

What about the irrigation backflow assembly?

Above-ground brass backflow preventer for your irrigation system splits during freezes too. An inexpensive insulated cover wraps it for the winter months. Install before first freeze. Prevents costly freeze damage. Alternatively, dispatched plumber can shut off + drain the irrigation system for winter (free with annual maintenance contract).

What if I'm renting? Is freeze prevention still my problem?

Texas tenant law usually puts FREEZE PREVENTION on the tenant (drip faucets during warnings, etc.) but PIPE INSULATION on the landlord. Document any visible un-insulated attic supply lines + ask landlord in writing for pre-winter inspection. If landlord refuses + a freeze burst happens, document the request â€” affects liability allocation.

How long does the dispatched plumber take for pre-winter inspection?

1-2 hours on-site, written report within 24 hours. Includes attic walkthrough, hose bib check, water heater inspection, thermal scan if requested. Cost: modest for a standalone visit, free with an annual maintenance contract. Most Austin homeowners schedule in October-November before first freeze warnings.
