Cleaning and flushing the black water holding tank with a tank cleaning wand. If your tank is equipped with a built-in flushing system, you will not require this.

Hand tools required for removing and installing drain plugs

If you lack any of these items, a Winter Readiness Kit can help you get started. They include a hand pump, a blow out plug, antifreeze concentration, and a small dehumidifier.

Which antifreeze is the best for RVs?

Antifreeze for your camper should be non-toxic and biodegradable. Select a product with a minimum burst protection rating of -50°F (-45°C).

Several excellent options are available on Amazon: Splash and Star Brite.

2. Remove All Water From The System

You must ensure that the water system has been completely drained. This is accomplished by opening all hot and cold faucets, as well as the toilet and outside shower.

Additionally, you will need to open the low-point drain lines; one for each of the hot and cold water lines.

3. Ensure That The Lines Are Not Obstructed

You’ll want to blow out the lines to ensure they’re completely clear. You can follow the instructions below to blow out the water lines.

  • You should circumvent any inline water filters.
  • Drain the fresh water tank, taking care not to include the gray and black holding tanks.
  • Drain the water heater and water lines.
  • To drain the water, open the hot and cold faucets.
  • Connect the blown plug to the inlet valve of your water heater.
  • Connect the opposite end of the blowout plug with an air compressor.
  • Adjust the air pressure to between 30 and 40 psi to avoid causing damage to the water line.
  • Blow forceful air into the lines using the air compressor.
  • Open your water valves one at a time to clear the lines of excess water.
  • Remember to shut off the valve after blowing out each line.
  • Repeat steps 10 and 11 to blow out all water lines.

4. Avoid Using The Water Heater

You will need to bypass the water heater using the water heater bypass. By bypassing the water heater, you avoid the need to add antifreeze to it.

Additionally, you should bypass or remove your filter prior to adding antifreeze to your system.

Locate your heater. It is most likely positioned on the exterior of your van, beneath a huge cover with a screen on the upper right-hand side.

Activate the screen. Behind it is an anode that is often removed when the tank is drained for winterization. Because the anode becomes loose with age, it should be replaced when it begins to appear aged. For the anode rod, you’ll need a 1- 1/16 socket.

Now enter your RV and look for the heater on the inside. To reach it, you may need to remove a cover.

The bottom of the heater receives cold water, while the top of the heater receives hot water. If your RV has a bypass valve, a third pipe will link these two pipes directly to one another.

The valve’s lever should be oriented in the direction in which you want the water to flow. If it is twisted 90 degrees in the direction of the bypass line, it will flow into the bypass line rather than into the tank.

To prevent antifreeze from entering the hot water tank, both valves on the hot and cold water lines should be turned off.

Remove the heater’s fuse to prevent it from operating when there is no water in it.

5. Water Pump Conversion

After that, you will install a water pump converter kit.

This enables us to bypass the freshwater tan and run the antifreeze through your water lines via the water pump.

6. Incorporate Antifreeze

You are now prepared to add the antifreeze. This will be accomplished in a series of steps to ensure that you have covered everything that will require it.

7. Activate The Water Pump

Open the closest faucet to you. You will turn on the hot and then the cold water until pink fluid is visible. After that, you’ll need to replace all faucets, including low point valves. Remember to take showers (both indoors and outside) and flush the toilet until you see antifreeze.

After that, you’ll go ahead and pour 1 cup of antifreeze down each drain.

When finished, turn off all faucets.

What To Avoid

You want to avoid contaminating the freshwater tank with antifreeze. Attempting to inject it through the pump into your system will consume a significant amount of antifreeze. Additionally, even when the tank is completely empty, there is still some water at the bottom that will react with the antifreeze, diminishing its effectiveness.

Ensure that the hot water tank is entirely drained. You must remove the drain stopper and open the pressure pop-off valve at the same time. If the residual water is not entirely drained, it can freeze, perhaps causing harm.

Bear in mind that you should also winterize your sinks. If antifreeze is not poured down sinks, water can accumulate in the curved part and freeze, causing damage.

Avoid using excessive antifreeze. Two gallons should be plenty to winterize an RV camper completely.

Remember to clean the grey and black water tanks as well. It is recommended that you fill them with fresh water with your fine chemicals and leave them for one week before draining. This will help you avoid any unwanted odors when you reopen the next season.

Don’t forget to maintain any equipment that contain water, such as an ice maker. You’ll want to winterize anything that has water running through it.

Why Is This Important?

When the temperature gets colder, any water in the RV camper runs the risk of freezing. If this water freezes and expands, it might bust the pipes, causing damage and potentially rendering the RV camper useless.

Depending on the amount of remaining water in the pipes, bypassing the winterization process could prove pricey. It’s preferable to obtain the supplies necessary to DIY the antifreeze process than to take a chance on frozen plumbing.

In order to avoid tank freezing, four-season RVs usually incorporate heated underbelly and tank heaters. However, these devices can fail.

Can You Put Rv Antifreeze In Hot Water Heater?

RV Antifreeze can be used in the hot water system. The antifreeze will not harm the tank, but it should be flushed out before using it again next spring to avoid corrosion.

How Do You Flush Antifreeze Out Of A Camper?

Dissolve it with water and pour it down the drains, or sprinkle baking soda on each drain. Rinse the system several times until the water no longer smells or tastes foul. To flush antifreeze from your RV water system, you can use a garden hose or municipal water supply instead of your RV water pump.

Can You Reuse Rv Antifreeze?
