Turning Off the Water Supply
Maintaining control over the water supply is the first step in the process of emptying your RV’s fresh water tank. By shutting off the water pump and disconnecting external water sources, you ensure that no additional water enters the tank during the draining procedure. This ensures that you have full control over the water being emptied, preventing any unexpected complications.
A. Shutting off the Water Pump
The water pump is responsible for pressurizing the water system in your RV, supplying water to faucets, showers, and other fixtures. Before emptying the fresh water tank, it’s crucial to shut off this pump to halt the flow of water. Depending on your RV model, the water pump may have a dedicated switch located near the control panel or within a compartment near the pump itself. Simply flip the switch to the “Off” position to stop the pump from drawing water into the system.
Shutting off the water pump not only prevents additional water from entering the tank but also ensures the safety of the pump itself. Running the pump while the tank is empty can lead to damage or premature wear, potentially necessitating costly repairs or replacements. Therefore, taking the time to turn off the water pump before emptying the tank is a proactive step in maintaining the longevity of your RV’s water system.
B. Disconnecting External Water Sources
In addition to the onboard water pump, many RVs are equipped with external water hookups that allow you to connect to city water supplies or external water containers. These sources provide a convenient way to replenish your fresh water tank while parked at a campground or RV site. However, when it comes time to empty the tank, it’s essential to disconnect these external water sources to prevent unintended water flow.
To disconnect external water sources, locate the connection point on the exterior of your RV where the water hookup is attached. Depending on the type of hookup, you may need to twist or unscrew a connection cap or release a latch to detach the hose. Once the connection is loosened, gently pull the hose away from the RV to fully disconnect it.
By disconnecting external water sources, you ensure that only the water contained within your RV’s fresh water tank is emptied during the draining process. This prevents any confusion or complications that may arise from multiple water sources being active simultaneously. Additionally, it allows you to maintain control over the water flow, ensuring a smooth and efficient emptying process.
Draining the Tank
A. Locating the fresh water tank drain valve
The freshwater tank drain valve is a vital component of your RV’s water system, allowing you to easily empty the tank when needed. Typically, you’ll find the drain valve located underneath the RV, near the freshwater tank itself. It may be situated towards the rear or underside of the vehicle, depending on the RV’s make and model. Look for a small lever or knob protruding from the tank’s exterior, often accompanied by a label indicating its purpose.
In some RVs, accessing the drain valve may require crawling underneath the vehicle or removing a protective panel. If necessary, use a flashlight to illuminate the area and locate the valve more easily. Once you’ve located the drain valve, take note of its position and ensure you have enough clearance to operate it comfortably.
B. Positioning a container to collect the drained water
Before opening the drain valve, it’s crucial to position a suitable container to collect the water as it empties from the tank. Choose a container large enough to hold the expected volume of water and place it directly beneath the drain valve. This could be a bucket, basin, or any other receptacle capable of safely containing the water without overflowing.
Consider the terrain and surrounding environment when selecting the container placement. Ensure the ground is level to prevent the container from tipping over or shifting during the draining process. Additionally, position the container in a location where the drained water can flow freely without causing any damage or inconvenience.
C. Opening the drain valve to release water
With the container in place, it’s time to open the fresh water tank drain valve and begin the draining process. Depending on your RV’s design, the valve may be operated manually by turning a lever or knob, or it may be electronically controlled via a switch or button inside the vehicle.
Carefully grasp the handle or knob of the drain valve and turn it counterclockwise to open the valve fully. As you do so, you’ll hear the sound of water flowing as it begins to drain from the tank. Keep a close eye on the container to ensure it captures the water effectively and adjust its position if necessary to prevent spills or splashing.
D. Ensuring complete drainage
Once the drain valve is open, allow the fresh water tank to empty completely. Depending on the size of your tank and the water pressure, this process may take several minutes to an hour or more. Be patient and monitor the draining progress periodically to ensure everything is proceeding smoothly.
As the tank empties, you may notice the flow of water slowing down or coming to a trickle. This indicates that the tank is nearly empty, and it’s time to prepare for the next steps in the emptying process. Once you’re confident that the tank is fully drained, you can proceed with any additional maintenance tasks, such as flushing the tank or inspecting for leaks and damage.
