The water heater is out! The last time it was out of the Airstream was when it was installed over 50 years ago. I am still deciding if I will put it back in as the previous owner didn’t use it and said it leaked. I seamed to hold water, but it is old! I will need to continue working on it. Most people recommend replacing the heater at this point.
To stop the water leaking inside the trailer, I had to seal all the seams with an Airstream sealant. I cut out the old sealant, cleaned the seam with alcohol, beaded in the sealant, then cleaned the seams with mineral spirits. With rain coming today, I had to get it done quickly. It is raining, so we will see if it worked tomorrow.
