Learn From What Other RV Owners Regret
January is the month when mobile RV techs start seeing the consequences of rushed or incomplete winterizing. Here are the most common problems — and how to avoid them.
1. Cracked PEX Lines
Even a small pocket of water can freeze and split tubing. The worst part? Damage often stays hidden until spring.
2. Burst Water Heater Tanks
Owners who forget to bypass the water heater may end up with a ruptured tank — a costly replacement.
3. Split Outdoor Shower Lines
Outdoor showers freeze first. Many owners forget to purge or antifreeze them.
4. Leaking Faucets or Mixing Valves
Freeze expansion damages delicate internal components.
5. Toilet Valve Fractures
Often missed because they’re small, but catastrophic once water pressure returns.
How to Prevent These Issues
Use proper antifreeze, fully blow out lines, verify your bypass system works, and check low-point drains. When in doubt, have a pro look it over.
If you’re worried something wasn’t winterized correctly, schedule a Mid-Winter RV Freeze Inspection with MilTech RV.
