How To Winterize An Rv Hot Water Heater

Alright, listen up, fellow RV adventurers! It's time to talk about something that's not as exciting as, say, planning your next road trip to the Grand Canyon. But stick with me, because winterizing your RV's hot water heater is actually a pretty cool (pun intended) topic. Why? Because it's like giving your trusty steed a warm hug on a chilly night, ensuring it's ready to roll when you are.

Why Bother, You Ask?

Well, imagine this: you're parked in the middle of nowhere, under a blanket of stars, ready to enjoy a nice, hot shower. But oh no, your hot water heater has decided to take a permanent siesta. Not cool, right? That's why we winterize, folks. To keep that hot water flowing like a trusty river.

First Things First: Drain the Darn Thing

Before we get started, let's talk safety. Make sure your RV is level, and turn off the water heater's power source. Now, locate the drain plug at the bottom of the water heater. It's usually a 1.5-inch NPT fitting. Grab your trusty wrench and get to work. Once you've removed it, open the pressure relief valve to let the water flow out.

Here's where it gets a bit gross. That water sitting in your heater? It's been there a while. It's not exactly a refreshing mountain stream. So, be prepared for some, ahem, interesting smells. But don't worry, we'll fix that later.

Blow It Out, Blow It All Out

Now that the water's out, it's time to blow out the lines. This is like giving your RV's plumbing system a big ol' kiss of life. Connect your compressor to the city water inlet, and turn it on. You want to blow out any remaining water, so keep an eye on the drain plug area. Once it's clear, you're good to go.

Fun fact: Did you know that water expands when it freezes? That's why we blow out the lines. We don't want any frozen water pipes turning our RV into a real-life game of whack-a-mole.

Time for a Fresh Start

Alright, now that we've gotten rid of the old, it's time to bring in the new. Well, not exactly new, but you know what I mean. We're talking about antifreeze here, folks. And no, we're not talking about the stuff you use to make cocktails (although, who are we to judge?).

Pour about a cup of RV antifreeze into the water heater through the opening at the top. This will help prevent any remaining water from freezing and causing damage. Then, fill the water heater with fresh water. Yes, you read that right. Fresh water. Not the stuff that's been sitting in there since your last trip.

Seal the Deal

Now, let's talk about the bypass kit. This little gadget is your water heater's best friend in the winter. It allows water to bypass the water heater when you're not using it, preventing any water from freezing inside. Install it according to the manufacturer's instructions, and you're good to go.

And there you have it, folks! Your RV's hot water heater is now ready to face the harshest of winters. You've just given it a makeover, a fresh start, and a warm hug all at the same time. Now, go forth and enjoy your RV adventures, knowing that a nice, hot shower is never far away.
