Understanding Your 2022 30BHS Cougar Camper’s Plumbing Systems

Before we dive into the practical steps, let’s briefly understand the key components of your camper’s water system. Knowing these parts will make the winterization process much clearer and more efficient. The Cougar 30BHS, like most modern RVs, features a fresh water tank, a city water connection, a water pump, a water heater, and various waste holding tanks.

Your fresh water tank supplies potable water when you’re not hooked up to a city water source. The water pump draws water from this tank and delivers it under pressure to your faucets, shower, and toilet. The water heater, often a 6 or 10-gallon unit, provides hot water for your comfort.

Waste holding tanks include the black tank for sewage and grey tanks for sink and shower wastewater. All these systems are interconnected by a network of pipes and lines, making them susceptible to freeze damage if water remains inside. Understanding this layout is the first step in effective winterization.

Essential Tools and Supplies for Winterizing Your Cougar Camper

Gathering your materials beforehand makes the winterization process much smoother. Don’t wait until you’re halfway through to realize you’re missing a crucial item. Preparation is key to a successful outcome.

Here’s a checklist of what you’ll need:

• Non-Toxic RV Antifreeze: Typically 2-3 gallons for most RVs, but having an extra gallon on hand is always wise. Ensure it’s propylene glycol-based and safe for potable water systems.
• Water Heater Bypass Kit (if not already installed): Crucial for preventing antifreeze from filling your water heater, which would waste product and be hard to flush out.
• Water Pump Converter Kit or Tube: This allows your water pump to draw antifreeze directly from its container.
• Air Compressor with an RV Blow-Out Plug: An alternative method to clear water from lines, or a good first step before adding antifreeze.
• Basic Hand Tools: Wrenches for drain plugs, screwdrivers for access panels.
• Safety Glasses and Gloves: Always protect your eyes and skin when working with chemicals.
• Bucket or Drain Pan: For catching water during draining.
• Hose for Flushing: A potable water hose for initial tank flushing.
• Tire Pressure Gauge: To check and adjust tire pressure.
• Battery Terminal Brush and Wrench: For battery maintenance.
• Moisture Absorbers (e.g., desiccant packets): For interior humidity control.
• Pest Repellents: Dryer sheets, peppermint oil, or commercial repellents.
• Tire Covers (optional but recommended): To protect tires from UV degradation.

Step-by-Step Water System Winterization for Your RV

This is the most critical part of winterizing your 2022 30BHS Cougar Camper. Follow these steps carefully to prevent any water from freezing and damaging your plumbing. This detailed process ensures every drop is either drained or replaced with antifreeze.

1. Empty and Flush All Holding Tanks

Start with empty and clean waste tanks. This is a crucial first step for hygiene and preventing odors over the winter.

1. Drain Black Tank: Connect your sewer hose and open the black tank valve. Once empty, flush thoroughly using your RV’s black tank flush system or a dedicated tank wand. Close the valve.
2. Drain Grey Tanks: Open your grey tank valves and allow them to drain completely. Rinse if desired, then close the valves.
3. Drain Fresh Water Tank: Locate the low-point drain for your fresh water tank, usually underneath the camper. Open it and let all water drain out. Close the valve once empty.

2. Drain the Water Heater

Bypassing and draining the water heater is essential. You don’t want to fill 6-10 gallons of antifreeze into it, as it’s wasteful and difficult to flush out in the spring.

1. Turn Off Power: Ensure both the electric and gas heating elements for your water heater are turned OFF.
2. Release Pressure: Open a hot water faucet inside the RV to release any pressure in the system.
3. Locate Bypass Valves: On the back of your water heater, you’ll find a set of bypass valves. Configure them to bypass the water heater. This usually involves closing the hot and cold water inlet/outlet valves and opening the bypass line valve. Refer to your Cougar owner’s manual for the exact configuration.
4. Remove Anode Rod/Drain Plug: Using a 1 1/16-inch socket, carefully remove the anode rod (Suburban models) or drain plug (Atwood/Dometic models) from the bottom of the water heater. Stand clear as water will rush out.
5. Flush Sediment: Once drained, you can use a water heater flush wand to clear any sediment from the tank. Replace the anode rod (if applicable) or drain plug once fully drained and flushed.

3. Drain All Low-Point Drains and Open Faucets

Now, remove as much residual water from the lines as possible before introducing antifreeze.

1. Open All Faucets: Open all hot and cold water faucets inside your RV, including the shower, kitchen sink, bathroom sink, and any outdoor shower.
2. Open Low-Point Drains: Locate and open all hot and cold low-point drain valves underneath your camper. Let the water flow until it stops.
3. Flush Toilet: Press the flush pedal on your toilet until no more water comes out.
4. Close Drains and Faucets: Once all water has drained, close all low-point drains and all interior faucets.

4. Introducing RV Antifreeze Into the System

This step replaces any remaining water with non-toxic RV antifreeze, ensuring comprehensive protection.

1. Bypass Water Pump (if applicable): If your water pump has a bypass line or winterization kit installed, connect your antifreeze suction hose to it. This allows the pump to draw antifreeze directly from its container.
2. Place Antifreeze Jug: Insert the other end of the suction hose into a fresh jug of RV antifreeze.
3. Turn On Water Pump: Turn on your RV’s water pump. It will begin drawing antifreeze into the system.
4. Open Faucets (One by One): Starting with the faucet furthest from the pump, open the cold side first until pink antifreeze flows steadily. Close it. Then open the hot side until pink antifreeze flows steadily. Close it.
5. Repeat for All Fixtures: Work your way through all faucets, the shower, and the toilet. Don’t forget the outdoor shower, if you have one. For the toilet, flush until pink antifreeze appears in the bowl.
6. Protect P-Traps: Pour about a cup of RV antifreeze down each drain (sinks, shower) to protect the P-traps from freezing. Pour some down the toilet and into the black tank as well.
7. Turn Off Water Pump: Once all fixtures have pink antifreeze flowing, turn off the water pump.

5. Winterizing the Water Filter and Other Appliances

Don’t forget these crucial elements of your 2022 30BHS Cougar Camper.

1. Remove Water Filter: If your RV has a built-in water filter, remove the cartridge. Empty the housing and store the cartridge in a safe, dry place or discard it, depending on its lifespan.
2. Refrigerator/Ice Maker: If your refrigerator has an ice maker or water dispenser, consult your appliance manual. Often, you need to run water through it until antifreeze appears, or disconnect and drain its water line.
3. Washing Machine (if equipped): Run a short cycle with antifreeze if your Cougar has a washing machine.

Protecting Exterior Components and Tires

Beyond the plumbing, your RV’s exterior also needs attention to withstand winter’s assault. Proper care now prevents cracking, fading, and structural damage later.

1. Clean Exterior and Check Seals

A clean exterior makes it easier to spot potential issues and protects surfaces.

1. Wash and Wax: Give your Cougar a thorough wash and apply a protective wax. This protects the finish from environmental damage.
2. Inspect Seals: Carefully inspect all exterior seals around windows, doors, and vents. Look for cracks or deterioration. Repair any compromised seals with appropriate RV sealant to prevent water intrusion, which can lead to costly interior damage.

2. Tire Care and Storage

Tires are susceptible to damage from cold, sun, and prolonged inactivity.

1. Inflate Tires: Inflate your tires to the maximum recommended PSI for storage, as indicated on the tire sidewall, not the door jamb. This helps prevent flat spots.
2. Cover Tires: Use specialized RV tire covers to protect them from harmful UV rays, which can cause cracking and premature aging.
3. Consider Jacks (Optional): If storing for an extended period, consider using leveling jacks to take some weight off the tires.

3. Propane Tanks and Slide-Outs

These components also require a quick check before storage.

1. Close Propane Valves: Turn off the main valves on your propane tanks. You can leave them attached or remove them for off-site storage in a well-ventilated area.
2. Lubricate Slide-Outs: Clean and lubricate your slide-out mechanisms according to your owner’s manual. Ensure slide-outs are fully retracted and sealed before winter storage.

Battery Care and Interior Preparation

The inside of your camper and its electrical heart, the battery, also need attention for long-term storage. Neglecting these can lead to dead batteries or unpleasant surprises in the spring.

1. Battery Maintenance and Storage

A dead battery can be a major headache. Proper care ensures it’s ready when you are.

1. Disconnect and Clean: Disconnect the battery’s negative terminal first, then the positive. Clean the terminals with a wire brush and a battery terminal cleaner to remove any corrosion.
2. Test Voltage: Use a voltmeter to check the battery’s charge. If it’s below 12.6 volts, charge it.
3. Store Indoors: Remove the battery from the RV and store it in a cool, dry place where it won’t freeze. A garage or basement is ideal.
4. Use a Trickle Charger: Connect the battery to a smart trickle charger or battery tender. This will maintain its charge throughout the winter without overcharging.

2. Interior Cleaning and Pest Prevention

A clean, protected interior deters pests and prevents mildew.

1. Thorough Cleaning: Clean the interior thoroughly. Vacuum carpets, wipe down surfaces, and clean the refrigerator and freezer. Leave the refrigerator door ajar to prevent mildew.
2. Remove Food and Valuables: Remove all perishable food items, canned goods that could freeze, and any valuables.
3. Pest Control: Place dryer sheets, cotton balls soaked in peppermint oil, or commercial pest deterrents in cupboards, drawers, and other potential entry points. Cover exterior vents to prevent rodent or insect entry.
4. Moisture Control: Place moisture absorbers (like DampRid) in various areas of the RV to combat humidity and prevent mold and mildew growth.
5. Ventilation: Crack a roof vent or two slightly, or use vent covers, to allow for some airflow without allowing precipitation in. This helps prevent stale air and mildew.

FAQ: Winterizing Your RV

Q1: How Much RV Antifreeze Do I Really Need for My 2022 30BHS Cougar Camper?

While 2-3 gallons is a common estimate, it’s always best to have 4-5 gallons on hand. The exact amount depends on the length of your plumbing runs, whether you have an ice maker, washing machine, or multiple bathrooms. It’s better to have extra than to run out halfway through.

Q2: Can I Just Blow Out the Lines With Air Instead of Using Antifreeze?

Blowing out the lines with an air compressor (set to 30-40 PSI) can remove most of the water, but it’s not foolproof. Small pockets of water can still remain in dips or low points, especially in P-traps and pump diaphragms. For maximum protection, especially in very cold climates, using RV antifreeze after blowing out the lines is highly recommended. You can also blow out the lines first to reduce the amount of antifreeze needed.

Q3: What If My Water Heater Doesn’t Have a Bypass Kit Installed?

If your 2022 30BHS Cougar Camper’s water heater lacks a bypass kit, you have two options: either install one (which is a recommended long-term solution), or fill the entire water heater with RV antifreeze. The latter will require significantly more antifreeze (6-10 gallons extra) and a more thorough flushing process in the spring. Installing a bypass kit is a worthwhile investment.

Q4: How Do I De-Winterize My Cougar Camper in the Spring?

De-winterization involves reversing the process: drain the antifreeze, flush the entire system thoroughly with fresh water until no pink residue or taste remains, sanitize your fresh water tank, reinstall water filters, and return your water heater to normal operation. Reconnect your battery and check all systems before your first trip.

Q5: Is It Safe to Leave the RV Stored Outside During Winter?

Yes, with proper winterization, your 2022 30BHS Cougar Camper can be safely stored outdoors. However, consider investing in a breathable RV cover to protect the exterior from harsh weather, UV rays, and debris. Ensure the cover allows for adequate ventilation to prevent moisture buildup and mildew.
