Why Winterize Plumbing in Las Vegas?

Though Las Vegas rarely sees extreme cold, overnight temperatures can dip below 32°F, especially in December and January. When this happens:

❄ Pipes can freeze and burst – Even a small crack can flood your home.

💧 Water heaters work harder – Sediment buildup reduces efficiency.

🚿 Drains may clog – Slower flow increases the risk of backups.

A few preventative steps can save you from expensive emergencies—like slab leaks or burst pipes—that require water damage restoration.

Top 8 Winter Plumbing Prep Steps

1. Insulate Exposed Pipes

• Focus on: Pipes in unheated areas (garages, crawl spaces, attics).
• Use: Foam pipe insulation or heat tape.
• Why? Prevents freezing and reduces heat loss.

(Also check out our pipe replacement services if your pipes are old and prone to cracks!)

2. Drain & Disconnect Outdoor Hoses

• Steps:
  • Turn off outdoor water supply valves.
  • Drain hoses and store them indoors.
  • Cover faucets with insulated sleeves.
• Why? Trapped water expands when frozen, cracking faucets and pipes.

3. Service Your Water Heater

• Flush the tank to remove sediment buildup.
• Check the pressure relief valve for leaks.
• Set temperature to 120°F for efficiency.

Pro Tip: Consider upgrading to a tankless water heater for endless hot water and better cold-weather performance!

4. Seal Gaps Around Pipes

• Use caulk or spray foam to seal holes where pipes enter walls.
• Why? Prevents cold drafts from reaching pipes.

5. Test Sump Pump & Drainage

• Pour water into the sump pit to ensure it activates.
• Clear gutters and downspouts to prevent ice dams.

6. Protect Outdoor Faucets

• Install frost-free hose bibs if you have old fixtures.
• Use faucet covers ($5–$10 at hardware stores).

7. Keep Interior Temperatures Stable

• Set thermostat to at least 55°F when away.
• Open cabinet doors under sinks to let warm air circulate.

8. Know Your Main Water Shut-Off Valve

• Locate the valve (usually in the garage or basement).
• Test it to ensure it works in an emergency.

Signs Your Winter Plumbing Has Damages

🚨 Low water pressure (possible pipe freeze)

🚨 Strange noises from pipes (banging or clanking)

🚨 Puddles near pipes or water heater (burst pipe or leak)

🚨 No hot water (water heater failure)

If you notice these, call a plumber immediately to prevent further damage!

FAQ

Q: How cold does it need to be for pipes to freeze?

A: While Las Vegas winters are generally mild, pipes can freeze when temperatures remain below 20°F for 6+ consecutive hours. However, vulnerable pipes (especially those in uninsulated exterior walls or crawl spaces) may freeze at 32°F if exposed to sustained cold winds. Metal pipes freeze faster than PVC, and even a small ice blockage can create enough pressure to cause pipes to burst. Homes in higher elevation areas like Summerlin or Anthem are particularly at risk due to cooler nighttime temperatures.

Q: Can I use a space heater to warm pipes?

A: Space heaters can provide temporary protection for pipes in garages or basements, but they should never be left unattended due to fire risks. For long-term solutions, pipe insulation (foam sleeves or heat tape) is safer and more effective. If you must use a heater, choose an UL-certified model with tip-over shutoff, keep it 3+ feet from flammables, and plug it directly into an outlet (no extension cords).

Q: Does homeowners insurance cover burst pipes?

A: Most policies cover sudden/accidental pipe bursts (like freezing), but neglect-related damage (e.g., failing to winterize or repair known leaks) is often excluded. To file a claim, document the damage with photos and contact your insurer immediately. Pro tip: Preventative maintenance records (like receipts for pipe insulation or plumbing inspections) can strengthen your case.

Q: How often should I flush my water heater?

A: Annually, especially in hard water areas like Las Vegas. Sediment buildup reduces efficiency by up to 30% and strains the system during winter. For gas heaters, also check the anode rod every 3 years to prevent corrosion. Tankless models need descaling every 1–2 years.
