Winterizing your Cougar travel trailer is crucial to protect it from the damaging effects of freezing temperatures and ensure it’s ready for adventure when spring arrives. Properly winterizing involves draining the water system, adding antifreeze, and taking preventative measures against pest infestations and weather-related damage, ultimately saving you costly repairs in the long run.
Why Winterizing Matters: Protecting Your Investment
Leaving your Cougar unprepared for winter can lead to burst pipes, cracked fixtures, and significant water damage, all of which can be incredibly expensive to repair. Furthermore, neglecting winterization can encourage rodents and insects to seek shelter inside your trailer, leading to unsanitary conditions and further damage. By taking the time to winterize properly, you’re safeguarding your investment and ensuring that your travel trailer remains in top condition for years to come.
Step-by-Step Winterizing Process
This guide outlines the essential steps for winterizing your Cougar travel trailer. Before you begin, consult your Cougar owner’s manual for specific instructions or recommendations relevant to your model.
1. Draining the Water System
This is the most important step. Water expands when it freezes, and that expansion is what bursts pipes and damages plumbing fixtures.
- Drain all tanks: Start by draining your fresh water tank, gray water tank, and black water tank. Ensure the drain valves are completely open and allow ample time for thorough drainage.
- Bypass the water heater: Turn off the water heater and allow it to cool completely. Locate the bypass valve(s) (usually located near or behind the water heater) and set them to the bypass position. This prevents antifreeze from entering the water heater tank, saving you antifreeze and preventing it from contaminating your hot water tank.
- Drain the water heater: After bypassing, remove the drain plug (usually a plastic plug at the bottom) of the water heater. Allow all the water to drain out. It is helpful to remove the pressure relief valve (usually on the top of the water heater) to facilitate draining. Replace the drain plug after draining is complete.
- Drain all water lines: Open all faucets (hot and cold) inside your travel trailer, including the shower and outdoor shower, if equipped. Flush the toilet multiple times. This will help to relieve pressure in the lines and allow the remaining water to drain. Locate the low point drain valves (usually located under the trailer) and open them to drain the water lines.
2. Adding RV Antifreeze
RV antifreeze is non-toxic and specifically formulated for use in potable water systems. Do not use automotive antifreeze, as it is poisonous.
- Bypass the water heater (again): Double-check that the water heater bypass valves are still in the bypass position.
- Choose your method: There are two common methods for introducing RV antifreeze: using a water pump converter kit or blowing out the lines with compressed air and then adding antifreeze.
- Water Pump Converter Kit: This is the preferred method by many. Install the converter kit to your water pump. Follow the instructions on the kit. Place the inlet hose of the converter kit into a container of RV antifreeze. Turn on the water pump.
- Blowing out the lines and using Antifreeze: If you choose to blow out the lines, you’ll need an air compressor with a regulator. Reduce the air pressure to 30-40 PSI. Connect the air compressor to the city water inlet. Open all faucets one at a time, allowing air to push out any remaining water. Repeat the process for the toilet. Once the lines are clear, close all the faucets and proceed with adding antifreeze.
- Antifreeze through the lines: With the faucets open, turn on the water pump (or connect the water pump converter kit to the antifreeze container). Starting with the faucet furthest from the pump, run the pump until pink antifreeze flows freely from the faucet. Repeat this process for all faucets (hot and cold) and the toilet. Don’t forget the outdoor shower, if equipped.
- Pour antifreeze into the drains: Pour a cup or two of RV antifreeze into each drain (sink, shower, toilet) to protect the P-traps from freezing.
3. Additional Winterizing Steps
- Batteries: Disconnect and remove the batteries from the travel trailer. Store them in a cool, dry place. Charge them periodically throughout the winter to maintain their charge.
- Tires: Cover the tires to protect them from UV rays. Consider using tire covers or moving the trailer onto wood blocks to prevent direct contact with the ground.
- Seal Gaps and Openings: Inspect your Cougar for any potential entry points for rodents or insects, such as gaps around pipes, wiring, or vents. Seal these openings with expanding foam or caulk.
- Empty and Clean: Remove all food items from the refrigerator and pantry. Clean the refrigerator thoroughly and leave the door ajar to prevent mildew. Clean the entire interior of the trailer to remove any potential food sources for pests.
- Propane Tanks: Turn off the propane tanks and consider removing them for storage. Store them upright in a well-ventilated area away from heat and open flames.
- Exterior: Wash and wax the exterior of your Cougar to protect the paint from the elements. Consider using a RV cover to further protect the trailer from snow, ice, and UV rays.
- Inspect the Roof: Thoroughly inspect the roof for any cracks, leaks, or damage. Repair any issues before winter to prevent water intrusion.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about winterizing a Cougar travel trailer.
FAQ 1: Do I really need to use RV antifreeze? Can’t I just drain everything?
While draining the water system is essential, residual water can still remain in the lines, fittings, and pump. This small amount of water can freeze and cause significant damage. RV antifreeze provides an extra layer of protection by displacing any remaining water and preventing it from freezing. It’s a small price to pay for peace of mind and protection against costly repairs.
FAQ 2: How much RV antifreeze do I need?
The amount of RV antifreeze you’ll need depends on the size of your Cougar and the complexity of its plumbing system. A good rule of thumb is to have at least 2-3 gallons on hand. You may need more if your trailer has a particularly complex plumbing system or a residential-style refrigerator with an ice maker and water dispenser.
FAQ 3: Can I use compressed air to blow out the lines instead of antifreeze?
Yes, you can use compressed air to blow out the lines. However, it’s crucial to ensure that all water is removed. Even a small amount of residual water can freeze and cause damage. Many people choose to blow out the lines and use antifreeze for maximum protection.
FAQ 4: How do I winterize the toilet?
After draining the water lines, flush the toilet several times to remove as much water as possible. Then, pour a cup or two of RV antifreeze into the bowl to protect the valve and prevent the P-trap from freezing.
FAQ 5: What if I have a washing machine in my Cougar?
If your Cougar has a washing machine, consult your owner’s manual for specific winterizing instructions. Generally, you’ll need to run the washer through a short cycle with RV antifreeze to protect the pump and lines.
