Winterizing Your Casita

Whether you park your Casita in your driveway over the winter, or at a commercial storage facility, preventing your rig's pipes from freezing should be a priority, if you want to avoid a hefty repair bill next season.

It’s essential to carry out some precautionary measures before freezing cold weather sets in for winter season. As soon as the air surrounding an unheated Casita’s water system dips below freezing, at 32°F or 0°C, your Casita water system is at risk. Extended exposure to sub-zero temperatures will cause ice to form in the fresh water tank, pump, hot water heater and water pipes, possibly causing the pipes to split.

Sanitizing Your Fresh Water Tank and Plumbing System

Many new RV owners do not realize that they need to sanitize their RV’s fresh water tank. This is the only way to ensure that you have safe RV drinking water before you set out on a road trip. If your RV has been in storage for a few weeks or months, you will likely have bacteria in your fresh water system. In order to make the water potable again, you need to sanitize your fresh water tank.

Even if you don’t usually drink water from your fresh water system you need to sanitize your fresh water tank and lines at least twice a year (every six months). You need to do it even more if you use the fresh water tank as a source for potable water. At the very least, you will be using this water for pets, for brushing your teeth and for washing up. Chances are you may use it for coffee and cooking, too, so it’s important not to skip this simple step.
