Winterizing Your RV

Winterizing your RV can be explained as preparing your RV to withstand even in extreme weather conditions. The best time to winterizing your RV is to do it before storing the RV for winters. Although winterizing is mostly involved in preparing RV’s plumbing system, but this also includes preparing exterior, interior, chassis, etc.

However, since plumbing is the most crucial part, it would best to starting from there. It is a method that requires you not to overlook even the smallest parts of the plumbing system. Before winterizing, you should take necessary precautions to protect your RV’s plumbing system—otherwise, any remaining water in the RV pipes or water storage tanks will freeze. As a result, the water lines of the RV will freeze, expand, and break at the end, making things even worse.

How to Winterize RV Water System

Prerequisites

Follow the below guidelines to start winterizing your RV’s water system;

  1. Step One: Firstly, remove all the inline water filters, and if there is one at the sink faucet, you should install a bypass hose. Once done, find a dump station and drain all the water storage tanks, including the water heater tank.
  2. Step Two: Now, after opening all the faucets, flush the toilet. Make sure to take the last bits of water out of your RV water system. This includes a shower as well, regardless of whether it is inside or outside. Now, find both the open and low point water drains. It would be great to use a 12V pump to make sure you take all the water out, i. Once you think there is no water left inside, don’t forget to turn off the system. Do the same for all the drains and then close the faucets.
  3. Step Three: If your RV is equipped with a bypass water heater system, use it to bypass the water heater. But if it doesn’t, install one by DIY or go to a local dealer who can install it for you. Remember that failing to do so means the water heater will fill with antifreeze; as a result, you will waste 6 to 8 gallons.
  4. Step Four: Now you have to install the water pump converter, which will be used to throw antifreeze into the water system.
  5. Step Five: Once you have installed the water pump, turn it on to pressurize and pump the antifreeze. Start from the faucet to the pump until it comes out from the other end. Repeat this very same process on all the faucets, including the outside shower, if your RV has one
  6. Step Six: Now, it’s time to flush the toilet. Keep flushing until you see the antifreeze coming out. Pour a cup in each drain and toilet and then flush again. It will make sure that the remaining water won’t freeze out.

That’s it. Now your RV’s water system is winterized, and it is all set for winter, allowing you to travel in extremely cold weather conditions without worrying much about your RV water system. You can keep your RV winterized until you reach your favorite campsite. Once you reach there, you should flush out all the antifreeze before refiling your water system.

But how to flush out all the antifreeze?

Well, for flushing out all the antifreeze, you have to attach a hose to your RV’s water hookup and then open all the faucets. Now you will see the water will run through the system, flushing out all the antifreeze. Keep it flushing until you see the clear water running.

How to Insulate Your RV Water Valves?

The best way to keep your RV warm and bitterly cold weather out is to use skirting around your RV. However, it doesn’t mean it is the only option you have got. Some RVers also use hay bales, but the problem with them is they are easily affected by mold and vermin. That is why it is suggested you to use skirting to keep RV pipes from freezing.

Here is how you can insulate your RV water valves,

1. Skirting the RV

Skirting the RV

Wrap skirting around your RV to keep RV pipes from freezing. This helps to absorb the heat while keeping the cold weather at bay. Using skirts as a shield to keep your RV also protects the underneath as of your recreational vehicle from external elements to protect outdoor RV water pipelines and valves.

This means it also means it protects the RV from the wind blowing beneath it that can suck the heat and freeze water holding tanks. This is why skirting is the best solution to insulate your RV.

2. Using the Heat Lamp

Having a heat lamp with you means you can easily melt any ice build-up. Since the water valves are can be found in an exterior compartment, making them more sensitive to freeze out. Having a small lamp heater can help to keep these compartments warm, eventually eliminating the risk of any damage. However, while using a heat lamp, you should never forget to turn them off when they are unused.

3. Avoid emptying Water Tanks Until They Are Full

Water Tank

Another common thing that you should always keep in mind is never empty tanks until they are near to full. This is because empty storage tanks can freeze instantly, which, as a result, form ice inside the valves. Moreover, when emptying the water tanks, make sure to keep at least ¼ of water inside, which will help against freezing.

4. Usage of Holding Tank Heater

If you are concerned about extremely cold temperatures, a holding tank heater could be useful to have. They act like an electric blanket keeping the tank safe from freezing. You can turn them off when the temperature gets normal.

5. Wrapping Exposed Water Lines

Yet another way to keep exposed RV water lines from freezing is to wrap them up. It will act as an added layer of insulation to all the exposed water lines of RV. To do that, you can use a tap, which is not only cheap but also easy to use. Or you can also use foam insulation to keep RV water lines from freezing.

How to Insulate Your RV in Cold Weather?

Insulating your RV means you are going to add an extra layer of insulation to your RV. It will not only keep RV pipes from freezing while camping but also keeps you warm and comfortable during your trip in cold weather conditions.

1. Sealing Around Doors and Windows

Although during summers, you don’t necessarily check gaps around your RV doors and windows, during winters, these tiny gaps play a critical role. Seal those little gaps around doors and windows to prevent both air and moisture from breaking in.

2. Window Film and Reflective Foil

Another best way to insulate your RV and keep RV water lines from freezing is the use of window film and reflective foil coverings. They are not only budget-friendly but also one of the most effective ways to insulate your RV windows. You can custom cut them to make them fit your RV windows. Moreover, they are also useful for absorbing heat and then keeping it inside the RV.

Wrapping Up

Although winter camping trips are fun and offer a lot of benefits and adventures, you have to face some challenges as well. Before hitting the road for winter camping, you have to consider your RV pipelines, plumbing system, and overall insulation of your recreational vehicle. However, taking all the precautions into consideration can help you to keep your RV water lines from freezing to get smooth hot water flow.
