As October comes to an end in Alberta, freezing temperatures are becoming a serious consideration for RV owners. Whether you’re wrapping up a summer of camping or preparing to store your trailer for winter, winterizing your RV can help prevent costly damage and make getting back on the road easier next spring.
Alberta winters can bring sudden temperature drops, snow, and extended periods of freezing conditions. Water left inside your RV’s plumbing system can freeze, expand, and damage pipes, faucets, pumps, and other components. A little preparation now can help protect your investment through the colder months.
Here’s what to know about winterizing your RV in Alberta.
1. Drain the Freshwater System
One of the most important steps in winterizing your RV is removing water from the plumbing system. When temperatures fall below freezing, trapped water can expand and crack pipes or damage plumbing fixtures.
Start by draining the fresh water tank, wastewater holding tanks, and water heater according to your RV manufacturer’s instructions. Open faucets and drain points as directed to help remove remaining water.
Your RV may also require its plumbing lines to be cleared using compressed air or protected with RV-specific antifreeze. The correct method depends on your model and plumbing setup, so consult your owner’s manual before proceeding.
Important: Never use automotive antifreeze in your RV’s potable water system. Only use products specifically designed for RV winterization, following the product instructions.
2. Protect the Water Heater and Plumbing Components
Your RV’s water heater, water pump, faucets, toilet, and exterior shower can all be vulnerable to freezing temperatures.
Before winterizing, make sure the water heater is turned off and has cooled down. Follow the manufacturer’s instructions for draining and protecting it. Never drain a hot or pressurized water heater.
Some RVs have a water heater bypass system that helps prevent antifreeze from entering the water heater tank. If your model has one, make sure it is used correctly as part of the winterization process.
Don’t overlook smaller components such as outside showers, water filters, low-point drains, and water lines hidden in storage compartments. These areas can retain water even after the main tanks have been drained.
3. Clean and Prepare Your RV for Storage
Winterizing involves more than plumbing. Giving your RV a thorough clean before storing it can help prevent unpleasant surprises when camping season returns.
Remove all food, crumbs, and garbage to discourage pests. Clean the refrigerator and follow the manufacturer’s recommendations for leaving it during storage. Make sure the interior is dry and remove items that could freeze or be damaged by moisture.
Check cupboards, storage compartments, and under-seat areas for anything that shouldn’t be left inside through the winter.
It’s also a good time to inspect your RV for signs of water leaks, damaged seals, or other maintenance concerns. Addressing issues before winter can help prevent them from becoming bigger problems later.

4. Inspect the Roof, Seals, and Exterior
Alberta’s winter conditions can be tough on an RV’s exterior. Snow, ice, moisture, and changing temperatures can put additional stress on roof seals, windows, doors, and other openings.
Inspect the roof and exterior seams for cracked sealant, loose trim, or visible damage. Pay close attention to vents, skylights, windows, and roof-mounted accessories. If you spot a concern, arrange the appropriate repair before storing your RV.
Avoid climbing onto the roof unless it is designed to support your weight and you can do so safely. When in doubt, have a qualified RV service professional inspect it.
A protective RV cover may be useful for some models and storage situations, but it should be appropriate for your RV and installed according to the manufacturer’s recommendations.

5. Check the Battery, Tires, and Propane System
Before putting your RV away for the winter, review the manufacturer’s recommendations for battery storage and maintenance. Depending on your battery type, you may need to disconnect it, maintain its charge, or store it in a suitable location.
Check your tires for visible damage and inflate them to the recommended pressure. If your RV will be sitting for several months, follow the manufacturer’s guidance for tire care and storage.
For propane systems, turn off appliances and follow the RV manufacturer’s storage instructions. If you suspect a propane leak or notice a problem with the system, don’t attempt an improvised repair. Have it checked by a qualified professional.
6. Plan for Alberta’s Changing Weather
In southern Alberta, late October is a smart time to prepare for winter, but the right timing depends on the forecast and where your RV is located. A sudden cold snap can arrive before you expect it.
If you’re still using your RV during the fall, keep an eye on overnight temperatures and make sure you know how to protect its plumbing when freezing weather is expected. Once you’re finished camping for the season, avoid delaying winterization until sustained cold weather arrives.
Before storing your RV, make a final check of windows, doors, roof vents, and exterior storage compartments. Secure the unit and follow the storage recommendations for your particular model.
7. Know When to Call an RV Service Professional
Winterizing can be a manageable do-it-yourself project, but every RV is different. If you’re unfamiliar with the plumbing system, unsure how to protect the water heater, or concerned about existing leaks or damage, professional assistance can help you avoid mistakes.
A service appointment is also a good opportunity to address maintenance concerns before your RV goes into storage. Taking care of small issues now may help reduce the chance of discovering a bigger problem when spring arrives.
