RV Water Pipes Freezing

Keep RV Pipes from Freezing

Braving the great outdoors in your RV during the chilly months is an adventure like no other. But let’s talk about a not-so-fun part of winter camping: the ever-looming threat of frozen pipes. Fear not, because with a sprinkle of wisdom and a dash of quick action, we can keep the water flowing and the good times rolling.

I’ll never forget that one frosty morning when I woke up to the dreaded realization that I hadn’t prepped my pipes for the cold snap. There I was, in my cozy RV sanctuary, suddenly turned ice fortress. That day, I learned the hard way that keeping your RV pipes from freezing isn’t just about avoiding inconvenience; it’s about safeguarding your home-on-the-go.

So, I dove headfirst into the world of anti-freeze tactics, from the simple act of letting water trickle through the pipes to wrapping them up in heat tape like precious gifts. Each strategy was a lesson learned and a disaster averted. And now, I’m here to share these nuggets of knowledge with you. Let’s tackle this wintry challenge together and ensure our RV adventures are memorable for all the right reasons.

Letting the Water Run

Ah, the joys of RV life! Picture this: you’re nestled in your cozy RV, the great outdoors just a zipper away, but then you remember—the dreaded freeze risk to your water pipes. Well, let me share a little trick that’s as simple as it sounds: keep that water moving! Just like you and me, water prefers to stay on the move. Let it sit too idle, and it might just decide to freeze up on you.

Here’s what I do: I keep a small stream of water flowing, about as thin as a pencil. It’s a neat little trick that’s saved my pipes more than once. Sure, when you’re living the RV dream, water can be as precious as gold. But you don’t need to open the floodgates! A tiny trickle will do the trick.

Now, I remember this one time I was camped out near this gorgeous but remote mountain range. The scenery was breathtaking, but let me tell you, water was as scarce as a snowball in the desert. In places like that, keeping a tap open even a smidge didn’t seem too wise. So, it’s definitely a tip best used when you’re parked somewhere with a bit of water abundance.

Keeping your RV’s water pipes from freezing doesn’t have to be a chore. A little bit of movement can go a long way. And hey, it’s also a great reminder to stay fluid and adaptable on your own adventures.

Drain Your Water Tanks

Oh, have I got a story for you about the time I learned the hard way to drain my RV’s water tanks! So, there I was, new to the RV life, parked for a winter retreat in the serene silence of a snowy landscape. Little did I know, my adventure was about to get a bit… icier.

Here’s the golden rule I learned: if you’re not planning on moving your home-on-wheels anytime soon, do yourself a favor and drain those tanks. Not only does it keep Jack Frost from turning your water storage into an ice block (which, believe me, is a headache to fix), but it also stops any sneaky rust or corrosion from setting up camp in your system.

The moment that taught me this? Coming back to my RV after a long day of exploring, only to find that my neglect had invited a symphony of cracks and leaks. Since then, I’ve made it a routine, almost a little goodbye ceremony to my RV before we part ways for a while. Drain the tanks, avoid the heartache. Trust me, your future self will thank you for taking that extra step.

Heat Tapes

Let me tell you about my secret weapon against the icy clutches of winter: heat tapes. These little lifesavers are like superheroes for your RV’s pipes. Picture this: you’re out there, braving the chill, and the last thing you want is for your water to freeze. Enter heat tapes, wrapping around your pipes like a warm hug, keeping them snug and ice-free.

The first time I tried them, I felt like I had unlocked a new level in RV living. It was a game changer. I simply wrapped these tapes around my pipes, and voila! They became a mighty fortress against the cold, ensuring my water flowed freely, no matter how low the mercury dropped. It’s like having your very own force field against the freeze. So, if you’re looking to keep your water pipes in liquid form (and who isn’t?), heat tapes are the way to go. Trust me, your RV adventure will be all the warmer for it.

Heating Pad

Let me introduce you to my RV’s little guardian angel: the heating pad. It’s like the cozy electric blanket you never knew your RV’s water tank needed. Now, I’m all for keeping things simple and straightforward, especially when battling the frosty foes of winter.

Here’s the scoop: attach a heating pad to your freshwater tank, and it’s like giving your water a warm embrace, ensuring it stays liquid, not ice. This genius gadget operates on a pretty basic, yet brilliant premise—the warmer the water, the less chance it has of turning into an ice cube.

But wait, it gets even smarter. Imagine a device that knows when to cozy up or cool down, all by itself. That’s right, some of these heating pads come with their own thermostats, automatically adjusting to the whims of the weather. On those bright, sun-kissed mornings, it dials down the heat, conserving energy. And when the night brings in the chill, it amps up, making sure the cold doesn’t stand a chance.

I remember one particularly crisp evening under a starlit sky, feeling a tad anxious about the plummeting temperatures. But then I remembered my trusty heating pad was on duty, and I slept like a baby, knowing my water would be just fine. It’s like having a vigilant, warm-hearted sentinel standing guard. So, if you’re looking to outsmart the cold, a heating pad might just be your best ally.

Insulating Pipes

Wrapping my RV’s pipes in layers of insulation felt like I was tucking them in for a long winter’s nap. You see, many RVs, mine included, have this habit of flaunting their water and sewage lines to the world, making them easy targets for the cold’s icy fingers.

So, before I even dream of chasing the snow, insulating those pipes is job number one. Now, I’m no DIY guru—I leave the magic to the professionals. I had them come over and apply this superhero of insulations, closed-cell spray foam. It’s like giving your pipes an armor that not only keeps them warm but uses the heat they already have to fight off the cold. Genius, right?

I’ll never forget this one trip, the first after getting the insulation done. There was this peaceful confidence, knowing underneath my RV, a warm fortress kept the water flowing, no matter how much the temperature dropped outside. It’s one of those moves that make you feel like you’ve leveled up in RV living. Insulating your pipes isn’t just a task; it’s an investment in uninterrupted adventures, regardless of the weather.

Skirt Your RV

Oh, skirting the RV – let me tell you, that was an adventure all on its own. It’s like giving your RV a cozy little enclosure, a safe space from the cold winds that just love to nip at your pipes. Think of it as building a fort, not with pillows and blankets, but with materials like insulated foam, vinyl, or heavy-duty plastic. And yes, I went the DIY route once, feeling all crafty and resourceful. Picture me, armed with materials, embarking on a mission to safeguard my mobile haven.

But for those who prefer a less hands-on approach, there are these fantastic pre-made skirting kits. EZSnap and Fabricover became my new best friends in the RV community. They’re like the easy-button of skirting—pop them on, and you’re pretty much set.

The difference it made? Night and day. Before skirting, every whisper of wind felt like a threat to my cozy interior. After, it was like my RV had its own little microclimate, snug and warm. That first winter with the skirting in place, I remember stepping out into the frosty morning, coffee in hand, marveling at how something so simple transformed my cold weather camping experience. So, whether you’re a DIY enthusiast or prefer the ready-made route, skirting your RV is like giving it a warm hug, telling those freezing temperatures, “Not today.”


Star Brite Non-Toxic Antifreeze

Buy Antifreeze from Amazon

Ah, the antifreeze saga – it’s a tale as old as time in the RV world. Now, I know what you’re thinking: antifreeze, isn’t that the stuff of warning labels and cautionary tales? Well, let me clear the air. With the right type and a bit of know-how, antifreeze becomes your RV’s winter warrior, guarding against the icy grip of freezing temperatures.

Here’s the lowdown: First up, you’ve got to give your RV’s water system a good clean-out. I mean really get in there – drain those tanks, fresh and waste alike. I used the blow-out plug on my RV, and it worked like a charm. Then, armed with either the RV’s own pump or a trusty hand pump, I introduced the antifreeze into the system. Of course, I rigged up a bypass kit because, let’s face it, no one wants their morning coffee to taste like the North Pole.

Now, the antifreeze you’re looking for isn’t your standard automotive fare. No, sir. This stuff is special – designed for RVs, non-toxic, and won’t wreak havoc on your system. And while it’s safe enough, I wouldn’t recommend adding it to your cocktail list.

When spring finally rolls around, and it’s time to say goodbye to your frosty friend, just flush the system thoroughly, refill, and maybe let it marinate a bit before one last drain to ensure all traces are gone. And remember, even though it’s non-toxic, dispose of it responsibly, like the eco-conscious camper I know you are.

Choosing the right antifreeze is a bit like picking the perfect winter coat. For chilly but not polar conditions, a -50F blend has got your back up to a cozy +12F. Facing the arctic abyss? The -100F mix keeps things liquid down to a bone-chilling -60F. Last winter, I opted for the heavy-duty stuff and watched in delight as my water lines laughed in the face of a deep freeze. It was a beautiful thing, my friends. So, gear up with the right antifreeze and keep those pipes flowing, no matter what winter throws your way.

What to Do If Your RV Pipes Freeze

Even with all the care and preparation in the world, I once found myself facing the RV owner’s winter nightmare: frozen pipes. The water trickled to a halt, a peculiar odor wafted from the faucet, and there it was—a frosty sheen on the pipes. It was the kind of morning that had me missing the simplicity of leaky faucets.

First things first, I learned quickly that frozen pipes wait for no one. Ignoring them meant risking a burst pipe scenario, which is as fun as it sounds (spoiler: it’s not fun at all). So, there I was, flashlight in hand, inspecting my pipes like a detective. Finding no cracks (thank goodness), I knew I had to act fast to thaw them out without turning my RV into an indoor swimming pool.

I kept the water mains on, a counterintuitive move that felt like keeping the engine running while fixing the car. But turning on the faucets was a game-changer; that tiny drip of hope meant I was on the right path. Heating the pipes became my mission. Armed with a portable heater and some heat tape—which, by the way, is more of a superhero gadget than actual tape—I waged war on the ice. And let me tell you, it’s a delicate balance. Too much heat too fast, and you’re in for a world of plumbing pain.

This ordeal taught me the importance of vigilance and the power of patience. It was a reminder that sometimes, the solutions we need are right in front of us, plugged into an outlet or wrapped around a pipe. And while I might not be ready to moonlight as a plumber, I know that with the right approach, even the iciest of problems can be melted away.

Final Thoughts

As we wrap up our frosty journey through the world of RV living in the chillier months, it’s clear that the battle against freezing pipes is one we can win with a mix of preparation, quick thinking, and a sprinkle of ingenuity. From the simple act of keeping a trickle of water flowing to the high-tech solution of installing heat tapes or embracing the warmth of a heating pad, each strategy has its place in our winterizing arsenal.

My adventures—and misadventures—with frozen pipes have taught me more than just the importance of insulation or the science of antifreeze. They’ve shown me that the heart of RV living beats strongest in the face of challenges.

Approach each frozen morning with a sense of adventure, a willingness to learn, and a readiness to apply the hard-earned wisdom shared by fellow travelers.

So, as you set out on your winter expeditions, keep these tales and tips close at hand.
