Winterizing your travel trailer is crucial to prevent damage from freezing temperatures. One essential step is properly draining the water heater. Here’s how to do it effectively.
First, ensure the water heater is neither hot nor under pressure to avoid scalding. Turn off the water heater and allow it to cool completely. Locate the power switches; one is typically on the water heater itself, accessible from outside the RV, and another is usually on or near the control panel inside your RV. Turn off all power sources to the water heater.
Next, shut off the water supply to the water heater. There’s usually a valve within a foot or two of where the pipe or hose enters the water heater. Close this valve to prevent more water from entering the tank during the draining process.
At this point, open the pressure relief valve (PRV). Wait until water stops flowing from the PRV before proceeding, and then leave the valve open. This will help to prevent a vacuum from forming in the tank, which can slow down the draining process.
Now, grab a bucket. This is crucial for catching the water as it drains.
Before draining, it’s a good idea to turn on a hot water faucet or two to relieve pressure within the water heater tank. Slowly unscrew the drain plug to start draining the unit. Use the bucket to catch the initial gallons of water. Once the flow slows to a trickle, fully remove the plug to allow the water heater to drain completely.
While the water heater is draining, examine the water in the bucket for rust, sediment, or scaling. If present, consider flushing the water heater again, replacing the anode rod, or planning for a new water heater. These are signs of internal corrosion or mineral buildup that can reduce the water heater’s efficiency and lifespan.
If the water heater is draining slowly, removing the anode rod can speed up the process. The anode rod is often attached to the drain plug, but if it isn’t, locate and remove it. Check the anode rod for scaling or corrosion. A heavily corroded anode rod should be replaced. The anode rod is a sacrificial component that corrodes before the interior of the water heater. If damaged, the water heater will start corroding, which is irreversible. Regular inspection and replacement of the anode rod are key to prolonging the life of your water heater.
In conclusion, draining the water heater is a critical step in winterizing your travel trailer. By following these steps, you can help prevent costly damage due to freezing and ensure your water heater remains in good working condition for years to come. Remember to inspect the drained water and anode rod for any signs of corrosion or sediment, and take appropriate action to maintain your water heater’s health.
