As another RVing season comes to a close, it’s time to prepare your pull-behind camper for the winter months so it’ll be ready to go when the weather warms up next spring.
We understand that some people camp in their RVs all year, and that’s great too.
However, if you’re one of the many people who store their pull-type RV during the winter, it’s critical to winterize your camper properly to prevent damage to your RV’s water system from exposure to sub-zero temperatures—this is the greatest risk of skipping winterization.
How to winterize a pull behind camper
This article will show you how to winterize a pull behind camper (step by step) so that when the weather warms up again, your favorite camper will be ready to go.
Although it may be tempting to simply store the camper and think about it next season, procrastination would almost certainly make the process of getting the camper up and running far more challenging (at best!)
Here are some simple steps to winterize your towable camper now so that it won’t be a concern in a few months.
Step-by-step instructions for winterizing a pull-behind camper
The main aim of winterizing your tow behind trailer is to keep the freshwater supply lines, pump, and tank from freezing.
You protect the entire waste drain system/setup, including the traps, the water heater, and so on, by winterizing.
The process outlined below is usually followed to fully winterize the trailer:
From side to side and front to back, level the camper. Now turn on all of the faucets.
The next move is to remove the water from the storage tank.
Turn the water pump’s switch to “ON” to accomplish this. Water will begin to drain from the tank.
Open all of the drain valves, including the one on the water heater in the unit. Open the exterior water service valve as well.
Continue to open and flush the camper’s toilet-flushing valve as the water drains from the system.
Then, when keeping down the inside of the tub, depress the hand-spray thumb button (on the telephone showerhead) and drain all water out of the flexible hose.
The showerhead can now be unscrewed and stored.
Switch off the pump’s switch. This can only be achieved after the unit’s storage tank has been fully drained of water.
The outlet hose from your pull behind camper’s water pump must be disconnected next. That is what you can do.
Set the valve to the “WINTERIZING” location if your camper has a factory-installed winterization package, then remove the plug.
If your machine doesn’t have this valve, detach the water pump’s inlet link and toggle it “ON” until the last drop of water is expelled.
Since this water is only around 1/2 cup, it is best caught in a rag or towel.
Your camper’s front end can now be lowered as far as the jack allows before the water stops draining. The jack should then be cranked all the way up. This aids in the drainage of any residual water.
Using an air compressor, add 50 lb. (at most) of air pressure to the camper’s city water inlet after the water has stopped flowing.
For your unit’s city water inlet, you can need to purchase air fittings with appropriate regulators.
Make sure all drain valves, faucets, the toilet flush valve, and the toilet shutoff valve are open before applying air pressure.
Also, make sure the pump outlet hose is disconnected and the water heater by-pass valve is set to the OPEN position.
Finally, both the water inlet and outlet valves should be shut.
Fast Tip: When winterizing the unit’s water heater, stop using air pressure as much as possible.
Fill the tub drain with one cup of non-toxic RV antifreeze. This is one of the most widely recommended methods for avoiding trap freeze-up nightmares.
Fast Tip: If you don’t want to use antifreeze, the best way to winterize your RV is to blow out the entire plumbing system with compressed air. Attach a blowout plug to the compressor air hose, then connect the plug to your camper’s water inlet. It’s not as complicated as it sounds. Then, at 30-second intervals, start pumping air into the camper’s plumbing system until the system is clear of all water.
Open the waste-holding tank dump valve and thoroughly empty (and flush) the tank.
This phase is important because any leftover sewage could cause significant damage to the tanks if it freezes.
Remove the batteries from the camper at the end.
Of course, you can keep the batteries in a dark, dry position where they won’t freeze.
Fast Tip: In the colder months, we recommend that you check the batteries and keep them fully charged. This will prolong the battery’s life.
After the winterization process is complete, remove all spilled antifreeze from all drain and faucet sections. Failure to do so can result in damage to the finish of the unit’s plumbing fixture.
That’s it- once the weather permits, your pull behind camper will be ready for an epic camping trip.
Please bear in mind that while the above method applies to many tow behind campers, there may be minor variations for your particular camper. As a result, before you begin, you should check your owner’s manual.
To summarize, winterizing your pull behind camper necessitates flushing out all drain lines as well as the storage tanks.
The entire water supply (including the unit’s water heater as well as the main water storage tank) should be fully drained.
If winter gets really harsh where you live, follow the steps outlined in this guide to finish the process in your camper.
You’ll be able to look forward to a happier reunion the next camping season!
