Step-by-Step Guide on Draining a Dometic RV Water Heater:
Step 1: Turn off the power supply.
Before starting the draining process, ensure that the water heater is turned off and disconnected from any power source. This will prevent any accidents or damage during the procedure.
Step 2: Locate the drain valve.
The drain valve is usually located on the exterior of the water heater. It is a small valve with a handle or knob for easy access. Consult your RV’s manual if you are having trouble locating it.
Step 3: Prepare necessary tools and equipment.
To drain the water heater, you will need a garden hose long enough to reach a suitable drainage area, a bucket or container to collect the water, and a pair of pliers or a wrench to open and close the drain valve.
Step 4: Attach the garden hose to the drain valve.
Connect one end of the garden hose to the drain valve and secure it tightly. Make sure the other end of the hose is placed in a suitable drainage location, such as a sewer drain or a bucket.
Step 5: Open the pressure relief valve.
To allow air into the water heater and facilitate the draining process, open the pressure relief valve located near the top of the heater. This valve will prevent a vacuum from forming inside the tank.
Step 6: Open the drain valve.
Using pliers or a wrench, turn the drain valve counterclockwise to open it. Be cautious as the water inside the tank may be hot. Allow the water to flow out through the garden hose and into the drainage area.
Step 7: Flush and clean the tank (optional).
If you notice any sediment or debris during the draining process, consider flushing and cleaning the tank. This can be done by filling the tank with clean water, then draining it again. Repeat the process until the water runs clear.
Step 8: Close the drain valve.
After all the water has been drained, close the drain valve by turning it clockwise until it is tightly closed. Ensure there are no leaks from the valve or any other connections.
Step 9: Disconnect the garden hose.
Once the drain valve is closed, disconnect the garden hose from the valve carefully. Avoid splashing any remaining water and ensure it is drained completely before storing the hose.
Step 10: Turn on the water heater.
Finally, turn on the water heater and restore power supply. Check for any leaks or irregularities before using the water heater again.
