Flushing Antifreeze From Your Camper: A Step-By-Step Guide

Flushing antifreeze from a camper is a crucial step in de-winterizing your vehicle. The easiest method is to run fresh water through the water system, either through the city water inlet or the fresh water holding tank, using the water pump. Open all faucets (hot and cold) and run fresh water through the system until it flows clear. This process ensures that all remnants of antifreeze are removed from the pipes, making the water safe for drinking and other purposes. Proper disposal of the antifreeze is also important, as some types may be harmful to the environment.

Using the water pump, run fresh water through the system until it flows clear

To flush antifreeze from your camper, you'll need to run fresh water through the system. This can be done through the city water inlet or the fresh water holding tank, using the water pump.

Here's a step-by-step guide to running fresh water through the system:

Step 1: Open All Faucets

Start by opening all the faucets in your camper, including hot and cold faucets in sinks and indoor and outdoor showers. Make sure to also open any water faucets connected to the 12-volt water pump.

Step 2: Turn on the Water Pump

With all the faucets open, it's now time to turn on the water pump. This will push fresh water through the system, helping to flush out any remaining antifreeze.

Step 3: Let the Water Run

Allow the water to run through the system for several minutes. You may also want to flush the toilet a few times while the pump is running to ensure that the water lines connected to the toilet are also flushed.

Step 4: Check the Water Colour

Keep an eye on the water flowing out of the faucets. At first, it may appear cloudy or discoloured due to the antifreeze. Continue running the water until it flows clear, indicating that most of the antifreeze has been flushed from the system.

Step 5: Close the Faucets and Turn off the Pump

Once the water runs clear, you can close all the faucets and turn off the water pump. This indicates that you have successfully flushed the antifreeze from the water lines, and your camper's water system is now free of antifreeze.

Remember, it is important to properly dispose of the antifreeze that was flushed from the system. Most RV antifreeze is biodegradable and non-toxic, but it is still a chemical that can be harmful to the environment. Do not dump it on the ground or down the sewer. Instead, collect it in a bucket and dispose of it at a designated dump station or recycling facility.

Don't dump antifreeze on the ground, it's harmful to the environment

When it comes to flushing antifreeze from your camper, it is important to remember not to dump it on the ground. While some types of antifreeze are labelled as non-toxic and biodegradable, they are still chemical materials that can be harmful to the environment.

Antifreeze is toxic to both humans and animals, and its bright green colour and sweet taste can be attractive to children and animals who do not know it is poisonous. Even in small amounts, it can be harmful and even fatal. It is estimated that 10,000 cats and dogs are accidentally poisoned by antifreeze each year through ingestion. Therefore, it is crucial to prevent any accidental exposure by properly disposing of antifreeze.

Additionally, antifreeze can be harmful to plants. If spilled on lawns or other vegetation, it will kill the grass and plants.

Antifreeze also has the potential to contaminate soil and water sources. Over time, antifreeze breaks down and forms acids, which can corrode the cooling system of a vehicle. In this process, the antifreeze becomes contaminated with heavy metals, fuel, and other toxic substances. These contaminants can then be deposited into the soil and water, poisoning organisms and damaging habitats.

To avoid these potential environmental and health hazards, it is essential to dispose of antifreeze properly. Take used antifreeze to a recycling centre or a hazardous waste management centre. Do not pour it down drains, on the ground, or into storm drains, sinks, or toilets. Many municipalities have hazardous waste protocols in place, so be sure to follow those guidelines for proper disposal. By taking these precautions, you can help protect the environment and prevent any harm to humans, animals, and plants.

Sanitise the water system with bleach

To sanitise the water system with bleach, follow these steps:

Preparation

Before you begin, gather the following supplies:

• A quarter cup of regular household bleach for every 15 gallons of water your fresh water tank holds. Bleach is a powerful chemical, so be sure to wear gloves when handling it.
• A gallon of water to mix with the bleach.
• Potable water (filtered or mineral water) to refill the tank.
• A siphon hose to help drain the tank.
• Painter's tape to mark the faucets so they are not used during the cleaning process.

Step 1: Turn Off the Water Heater and Water Pump

Turn off your water heater and run hot water for a minute or two to remove any heated water before draining it. This will prevent damage to the tank. Next, turn off the water pump to control the water flow and ensure bleach doesn't end up in the wrong places. If you have a water filter installed, remove it or divert the water flow away from it, as bleach can destroy water filters.

Step 2: Drain the System

Drain the water from your tank. If the water has been sitting for a while, it is best to drain the entire tank, as stagnant water can harbour bacteria. If you are sure the water is safe, you can drain it until only about a quarter of the tank remains.

Step 3: Prepare Bleach Mixture and Add It to Your Water Tank

Mix the bleach and water in a bucket, using approximately one gallon of water per quarter cup of bleach. This mixture will be strong enough to clean a 10-gallon camper tank, so adjust the volume accordingly for larger tanks. Pour the diluted bleach into your water tank.

Step 4: Fill the Tank With Water and Pump It Through the System

Fill your tank with clean water to ensure the bleach reaches all surfaces. Let the bleach solution sit in the tank for a few hours, then turn on the water pump and open all faucets. Keep each faucet running until you can smell bleach, then turn it off and mark it with painter's tape.

Step 5: Let the Water Sit for 12 Hours

After cleaning the faucets, refill the tank and let the water sit for about 12 hours. Do not use the water during this time.

Step 6: Drain the Tank and Flush the System

Finally, drain the tank and flush the system by refilling it with clean water and draining it again. Repeat this process three to four times to ensure all traces of bleach are removed.

Additional Tips:

• The sanitisation process can take up to 14 or 15 hours, depending on the size of your camper, so it is recommended to start early in the day.
• Regular sanitisation of your water tank is important to prevent the growth of bacteria, viruses, and cysts. Aim to clean your tank twice a month.
• If you prefer not to use bleach, you can use vinegar or acetic acid as an alternative, but these methods will take longer.

Drain the fresh water holding tank before adding potable water

To flush antifreeze from your camper, you'll need to drain the fresh water holding tank before adding potable water. This is an essential step to ensure your water system is safe to use. Here's a detailed guide on how to do it:

First, locate the fresh water holding tank in your camper. This is usually located near the front or back of the vehicle, often with a small access door. Open the door to access the tank. If your camper has multiple tanks, make sure you locate the correct one.

Next, you'll need to drain the existing antifreeze from the tank. Place a bucket or container underneath the tank's drain valve to collect the antifreeze. Open the valve slowly to control the flow and avoid spills. Continue draining until the tank is completely empty. Remember, it's important to properly dispose of the antifreeze; most types are biodegradable, but check before disposing of it.

Once the tank is empty, close the drain valve securely. Now, you can prepare to add potable water. Connect a hose to your camper's water inlet, ensuring a tight fit to prevent leaks. Turn on the water supply and begin filling the fresh water holding tank. You may need to open a faucet to allow air to escape and facilitate faster filling.

Monitor the water level in the tank as it fills. When the tank is nearly full, turn off the water supply and disconnect the hose. Securely close the inlet to prevent leaks while your camper is in use.

Now that your fresh water holding tank is filled with potable water, you can continue with the process of flushing the antifreeze from your camper's water system. Open all water faucets, including sinks, showers, and toilets, and let the water run for several minutes. This will ensure that any remaining antifreeze is flushed out through the system.

After flushing, close the faucets and inspect the water flow and pressure. Check for any signs of leaks or malfunctions. If everything appears normal, your camper's water system is now safe to use, and you can enjoy clean, potable water during your travels.

Remember, it is crucial to follow proper procedures when dealing with antifreeze and water systems in your camper. Always refer to your camper's manual for specific instructions and safety precautions.

Reinstall water filter cartridges

Reinstalling water filter cartridges is a crucial step in de-winterizing your camper. This process ensures that your water system is clean and safe to use. Here is a detailed guide on how to do it:

Firstly, locate the water filter cartridges in your camper. These are typically found near the water pump or the fresh water holding tank. Turn off the water supply to the camper and relieve any pressure in the system by opening a faucet. You may also need to disconnect the water hoses to access the filter housing.

Next, carefully remove the old water filter cartridges. They may be secured with a twist-and-lock mechanism or a simple screw-on cap. Make sure to note the orientation of the cartridges to ensure proper installation of the new ones. Some cartridges may be colour-coded, with the colour indicating the direction of water flow.

Once the old cartridges are removed, clean the housing with a mild detergent solution and a soft brush. Rinse thoroughly with fresh water and ensure that the housing is completely dry before proceeding.

Now, you can install the new water filter cartridges. As mentioned, ensure that they are oriented correctly and secured properly. If the cartridges use a twist-and-lock mechanism, you may need to apply some plumber's grease to the rubber gasket to create a watertight seal.

After the new cartridges are installed, reconnect the water hoses and turn on the water supply. Check for any leaks around the filter housing and ensure that the water flow is functioning correctly.

Finally, run the water through all the faucets in your camper for a few minutes to flush the system. This will ensure that any loose particles or residual chemicals are removed.

By following these steps, you will have successfully reinstalled your water filter cartridges, ensuring clean and safe water for your next camping trip.
