How to Winterize Your nuCamp Tab 400: A Complete Step-by-Step GuidePreparing your nuCamp Tab 400 for winter is essential to protect your camper from freezing temperatures and costly damage. Winterizing ensures that your plumbing system, appliances, and exterior components remain in good condition during the cold months. In this guide, you’ll learn how to properly winterize a nuCamp Tab 400 with easy-to-follow steps. Whether you’re storing your camper indoors or outdoors, these tips will help you keep it ready for spring adventures.
Why Winterizing Your nuCamp Tab 400 Is Important
Cold temperatures can freeze water inside the plumbing lines, tanks, and fittings, leading to cracks and leaks. Appliances like the water heater and pump can also suffer damage if not drained and protected. Winterizing helps avoid expensive repairs and extends the life of your camper.
When to Winterize Your Tab 400
The best time to winterize your nuCamp Tab 400 is before the first hard freeze. If nighttime temperatures are consistently below freezing, it’s time to take action. Some RV owners start the process in late fall to stay ahead of the weather.
Supplies You’ll Need
Before starting, gather these supplies:
-
RV non-toxic antifreeze (2-3 gallons)
-
Water heater bypass kit (if not already installed)
-
Water pump converter kit or hose adapter
-
Socket wrench set
-
Clean bucket
-
Freshwater tank cleaning wand (optional)
-
Towels or rags
Step 1: Drain the Fresh Water System
Empty the Freshwater Tank
Begin by draining the freshwater tank completely. Locate the freshwater drain valve underneath the camper and open it to release all water.
Drain the Water Heater
Turn off the water heater and let it cool. Remove the drain plug using a socket wrench and allow all the water to drain. Make sure to open the pressure relief valve to speed up the process.
Drain the Grey and Black Tanks
Visit a dump station or use your home sewer connection to empty the grey and black water tanks. Flush them thoroughly with water to remove any residue.
Step 2: Bypass the Water Heater
Most nuCamp Tab 400 campers come with a water heater bypass. Check behind the water heater access panel and turn the valves to the bypass” position. This step ensures that antifreeze does not fill the water heater tank.
Step 3: Open All Faucets and Drains
Open all interior faucets, including the kitchen sink, bathroom sink, and shower. Don’t forget the outside shower if your camper has one. Open both hot and cold sides to help remove any remaining water from the lines.
Step 4: Blow Out Water Lines (Optional But Recommended)
If you have an air compressor, use it to blow out the water lines at low pressure (around 30-40 PSI). Attach the compressor to the city water inlet and blow air through the system until no more water comes out of any faucet or drain. This step provides extra protection against freezing.
Step 5: Pump RV Antifreeze Through the Plumbing
Connect the Antifreeze
Attach a water pump converter kit or use a short hose to connect the RV antifreeze container to the water pump inlet.
Run the Pump
Turn on the water pump. Starting with the faucet farthest from the pump, open each faucet (hot and cold sides) until pink antifreeze runs out. Do this for all faucets, the shower, and the toilet.
Don’t Forget the Outside Shower
Open the outside shower and let antifreeze run through both hot and cold sides.
Step 6: Add Antifreeze to Drains and Tanks
Pour about a cup of RV antifreeze into every drain (kitchen sink, bathroom sink, and shower) to protect the P-traps. Also, pour some antifreeze into the toilet bowl and flush it to protect the waste tank valve.
Step 7: Final Checks
-
Double-check that all water lines have antifreeze.
-
Make sure the water heater is still bypassed.
-
Close all faucets and drains.
-
Remove the antifreeze hose from the pump and replace any access panels.
Optional: Battery and Tire Care
Battery Storage
If storing the camper for several months, remove the battery and keep it in a warm, dry place. Periodically check and charge it.
Tire Maintenance
Inflate tires to the recommended pressure and consider placing the camper on tire blocks or moving it occasionally to prevent flat spots.
Storing Your nuCamp Tab 400
Indoor Storage
If you have access to indoor storage, this is the best option for protecting your camper from snow, ice, and moisture.
Outdoor Storage
If storing outdoors, use a high-quality RV cover designed for your model. Make sure all vents are closed, and consider using moisture-absorbing products inside to prevent mold.
Tips for De-Winterizing in the Spring
When the weather warms up, it’s time to de-winterize your nuCamp Tab 400. Here’s what to do:
-
Refill the freshwater tank.
-
Run clean water through all faucets to flush out antifreeze.
-
Sanitize the freshwater system.
-
Check the water heater and reset the valves.
-
Test all appliances before hitting the road.
Common Mistakes to Avoid
Forgetting to Bypass the Water Heater
If you don’t bypass the water heater, you’ll waste gallons of antifreeze.
Using Automotive Antifreeze
Only use RV non-toxic antifreeze designed for potable water systems.
Not Draining Water Completely
Even a small amount of water can freeze and damage lines or fittings.
Skipping the Outside Shower
It’s easy to overlook, but the outside shower is just as vulnerable to freezing as interior plumbing.
Winterizing your nuCamp Tab 400 is a simple but important process that protects your investment and ensures it’s ready for spring travel. With the right tools, a little time, and attention to detail, you can complete the process yourself and avoid costly repairs. Whether you store your camper inside or out, these steps will help keep it in great shape all winter long. Taking care of your camper now means you’ll be ready for stress-free adventures as soon as the warm weather returns.
