Winterizing Your RV and Camper to protect your water systems from freezing this season.

Whether you’re tucking your RV away for winter or planning a cozy winter stay, winterizing the water system is crucial to prevent damage from freezing. Here’s your guide to winterizing based on your needs. Plus, remember that Dalton Jodrey Plumbing and Heating offers pump-out services if you’re planning to live in your RV over the winter.


For Those Storing Their RV Over the Winter

If you’re not using your RV this winter, it’s essential to winterize your water system fully. Here’s a step-by-step guide:


  1. Drain All Water Tanks Completely

    • Empty your fresh water, gray water, and black water tanks to prevent freezing. Dalton Jodrey can assist with pump-out services if needed.

    • Tip: Rinse your gray and black tanks thoroughly after emptying to prevent lingering odors.


  2. Flush the Water Heater

    • Turn off your water heater and allow it to cool down. Then, open the pressure relief valve and remove the drain plug to drain it completely.

    • Important: Avoid using antifreeze in the water heater. Just drain it thoroughly.


  3. Add Non-Toxic RV Antifreeze

    • Pump non-toxic RV antifreeze through your water lines to protect them from freezing. Run antifreeze through each faucet, shower, and toilet.

    • Tip: Antifreeze is essential for all lines, especially the water pump and interior pipes, as any leftover water can freeze and damage them.


  4. Blow Out Water Lines

    • Use compressed air to blow out the water lines, ensuring that no water remains in the pipes.

    • How to Do It: Attach an RV blowout plug and set your compressor to 30-40 PSI to avoid over-pressurizing.


  5. Add Antifreeze to Holding Tanks

    • Pour a small amount of RV antifreeze into each holding tank. This step can prevent any residual moisture in the tanks from freezing and causing damage.


  6. Open Faucets and Drain Valves

    • Open all faucets, showerheads, and drains to allow any remaining water to flow out. This ensures no water is left that could freeze.

    • Don’t Forget: Make sure to winterize outside faucets and hose bibs, too.


  7. Check Seals and Connections

    • Inspect all hoses, seals, and connections for any cracks or leaks. Freezing temperatures can worsen minor issues, so address them now.


  8. Insulate Exposed Pipes (Optional)

    • If you plan to store your RV in an unheated space, adding some foam insulation to exposed pipes can add extra protection.


For Those Living in Their RV During the Winter

If you’re planning to live in your RV throughout the winter, Winterizing Your RV and Camper takes on a different approach. Here’s how to protect your water system while keeping everything functional:


  1. Drain Waste Tanks Regularly with Pump-Out Services

    • Ensure regular pump-outs to keep your waste tanks clear, as freezing can create blockages. Dalton Jodrey offers pump-out services that are especially helpful for stationary RVs in winter.

    • Tip: Keep tanks as empty as possible to avoid freezing issues and add a small amount of RV antifreeze after each pump-out.


  2. Insulate and Heat Key Water Lines

    • Apply foam pipe insulation to your water lines, especially any exposed areas. Heat tape around water lines can also prevent freezing.

    • Safety Tip: Use heat tape specifically designed for water pipes and follow safety guidelines.


  3. Keep Water Moving

    • Run your water periodically to prevent it from freezing. A slow drip in the kitchen faucet can help keep the flow going.

    • Tip: This is especially effective if temperatures drop dramatically overnight.


  4. Add RV Antifreeze as a Safety Measure

    • Run a diluted amount of RV antifreeze through your drains to prevent freezing in the sink traps.

    • Important: Make sure not to use too much as it can interfere with pump-out services.


  5. Install Tank Heaters for Black and Gray Tanks

    • Tank heaters are highly recommended if you’re planning to live in your RV for the winter, as they keep holding tanks from freezing.

    • Tip: Some heaters come with automatic shut-offs, making them convenient and energy-efficient.


  6. Use a Small Space Heater Inside

    • Place a small space heater in compartments where water pipes run. This can prevent internal pipes from freezing and bursting.

    • Caution: Always follow heater safety guidelines to avoid fire hazards.


  7. Ventilation and Moisture Control

    • Use a dehumidifier to control condensation inside the RV, which can help reduce ice build-up on windows and walls.


  8. Regularly Monitor for Ice Build-Up

    • During very cold spells, check the exterior water lines and connections regularly. If you notice ice, thaw it before it spreads and causes issues.


  9. Protect Exterior Water Connections

    • Cover and insulate any exterior water connections to prevent freezing. Consider using a water hose with built-in insulation.


  10. Have Emergency Supplies on Hand

    • Keep extra blankets, a backup space heater, and additional antifreeze on hand in case of power outages or unexpected temperature drops.


Conclusion

Winterizing your RV water system is critical in Nova Scotia’s harsh winter conditions. Whether you’re storing your RV or planning to live in it, following these steps can protect your investment and keep things running smoothly. And remember, Dalton Jodrey Plumbing and Heating is here for reliable pump-out services and advice to help you through the season.

By taking these precautions, you’ll avoid the stress and expense of frozen pipes, cracked tanks, or water system repairs, ensuring a comfortable winter, no matter where the road takes you.
