Emptying an RV fresh water tank is a simple task that is essential for maintaining the cleanliness and functionality of your recreational vehicle. In this article, we will provide a step-by-step guide on how to properly empty an RV fresh water tank, as well as discuss some important considerations and tips to keep in mind.
Step 1: Locate the Fresh Water Tank
The first step in emptying an RV fresh water tank is to locate it. This may seem obvious, but the location of the fresh water tank can vary depending on the make and model of your RV. In most cases, the fresh water tank is located under the RV, either near the front or the middle of the vehicle. It is usually a large, rectangular tank made of plastic or metal.
Step 2: Shut off the Water Supply
Before you start emptying the fresh water tank, you need to shut off the water supply. This will prevent any additional water from entering the tank as you are emptying it. To shut off the water supply, you will need to locate the valve that controls the flow of water into the tank. This valve is usually located near the inlet hose that supplies water to the tank. Once you have located the valve, turn it to the “off” position to stop the flow of water.
Step 3: Drain the Tank
Now that the water supply has been shut off, you can begin draining the tank. To do this, you will need to locate the drain valve on the bottom of the tank. This valve is usually located near the center of the tank and is easily identifiable by its handle. Once you have located the drain valve, open it by turning the handle counterclockwise. As the valve opens, water will begin to flow out of the tank and into a drain or onto the ground.
Step 4: Empty the Tank Completely
It is important to completely empty the fresh water tank to ensure that it is thoroughly cleaned and free of any debris or contaminants. To do this, you will need to allow the water to drain until the flow slows to a trickle. This may take several minutes or longer, depending on the size of your tank. Once the flow has slowed, you can close the drain valve by turning the handle clockwise.
Step 5: Disconnect and Store the Hoses
Once the fresh water tank has been emptied, you will need to disconnect and store the hoses that are used to fill and drain the tank. To do this, simply unthread the hoses from the tank and the inlet/outlet valves, and store them in a safe and secure place.
Important Considerations and Tips
There are a few important considerations and tips to keep in mind when emptying an RV fresh water tank:
Use a hose that is appropriate for the task: To properly drain the tank, you will need to use a hose that is long enough to reach a drain or a suitable area on the ground. It is also important to use a hose that is sturdy and capable of handling the flow of water without breaking or leaking.
Dispose of the water properly: When emptying the fresh water tank, it is important to dispose of the water properly. In most cases, this means connecting the hose to a drain or allowing the water to flow onto an area of the ground that is not sensitive to water runoff. It is important to avoid allowing the water to flow into areas where it could cause damage or pollution.
Clean the tank thoroughly: Once the tank has been emptied, it is a good idea to clean it thoroughly to ensure that it is free of any debris or contaminants. This can be done by rinsing the tank with a mild cleaning solution and a soft cloth or sponge. Be sure to pay extra attention to any corners or crevices, as these areas can often harbor dirt and grime.
Use a water tank treatment: After the tank has been cleaned and dried, it is a good idea to add a water tank treatment to help prevent the growth of bacteria and algae. There are a variety of water tank treatments available on the market, so be sure to choose one that is specifically formulated for use in RV fresh water tanks.
Flush the system: Once the tank has been emptied, cleaned, and treated, it is a good idea to flush the entire RV water system. This will help to ensure that any remaining contaminants are removed from the pipes and fixtures. To flush the system, simply fill the tank with clean water and run the water through all of the pipes and fixtures until it is clear and free of any debris.
By following these steps and keeping these considerations in mind, you can easily and effectively empty an RV fresh water tank. Doing so will help to maintain the cleanliness and functionality of your recreational vehicle, ensuring that you can enjoy your travels with confidence and peace of mind.
