Opening Up the Airstream After a Long Winter’s Sleep

Last October, we had to do something to the Airstream that we had never done in our 3+ years of owning it — we had to winterize it. While our Airstream was born in Ohio, it had always spent winter in warmer locales, with us in it. But, we decided to settle into a condo in one of the coldest places in the contiguous US where winter lasts a very long time, so we had to winterize before tucking it in to storage for a long winter’s sleep.

We aren’t expert winterizers, but we are pretty good at Googling and YouTubing, and found the process to be pretty simple. We followed the same process the factory uses — empty the tanks, drain the hot water heater, blow out the lines with an air compressor, drain the low points, and put some RV antifreeze down each drain.

The low-point valves on the 27 are found between the two tires on the driver side.
While using the compressor, open each faucet one by one to make sure all of the water is blown out.
We poured antifreeze down the kitchen sink, bathroom sink, shower drain, and toilet.

As I said earlier, winter lasts pretty late into the year here in Bozeman, so we didn’t get the chance to pull the Airstream out of storage until May 15th, when we booked two nights at Bozeman Hot Springs Campground to make sure all systems were go. This is not our first time staying at the hot springs — you can read about our previous stays here, here, and here. Here’s what we checked/tested during our post-winter shakedown:

  • Ran city water through kitchen, bathroom, and shower faucets, as well as the toilet, to make sure all had good water pressure and there were no visible leaks.
  • After disinfecting the fresh tank with a bleach water mix, turned on the water pump and ran water through all faucets and toilet to make sure water pressure was good and water pump seemed to function properly without any leaks.
  • Filled hot water heater with water and checked that there was hot water at all faucets, along with good hot water pressure, while first using the water heater on electric and then on propane. Also checked to make sure there were no leaks at hot water heater.
  • Made sure the fridge and freezer operated properly on both electric and propane.
  • Made sure the air conditioning operated properly.
  • Made sure the furnace operated properly.
  • Made sure the microwave worked.
  • Made sure the oven and stove both functioned properly.
  • Made sure the solar system was working properly in conjunction with the batteries.
  • Made sure the propane detector is functional.
  • Made sure the smoke/carbon monoxide detectors are functional.
  • Made sure all fans, including the fantastic fans, the vent fans in bathroom & shower, and the stove vent fan are all functional.
  • Made sure all of the lights are working properly.
  • Made sure the electric awning functioned properly.
  • Did a visual inspection of the roof.
  • Did a visual inspection of the tires and made sure the tire pressure monitoring system was working properly after reinserting the batteries into each monitor.
  • After replacing a propane tank monitor, made sure both tank monitors were reading correctly.

It was after that last item that we realized we had a problem. Up to this point, our propane had been functioning properly off of the one tank we had open. When we opened the second tank after replacing the monitor, we heard pssssshhhhhh. Not good. We had a leak, and a very substantial one at that. I was literally able to put my finger on the leak and found that the rubber ring had disintegrated and this is where the propane was leaking from.

We shut the propane off and disconnected it, and then we went in search of the parts to fix it. Thankfully, we were in our own city, so we had ideas of where to look. Unfortunately, Bozeman doesn’t have a Camping World, Tractor Supply, Cabela’s, or Gander Mountain. It was also a Sunday, so that meant that all of the RV dealerships that might have a decent parts selection were closed. We tried Lowe’s and Home Depot first, but they only had replacement hoses for propane grills, which are not the right part. We checked Ace Hardware, and they had almost the right part, but the hose was too long (15″ instead of 12″). We then went to a local hardware store called Kenyon Noble and an employee there was able to help us immediately. They had the right part, except the connecting piece wasn’t exact. Our propane hoses had what’s called an NPT thread where as the hoses at Kenyon Noble had an inverted male thread. In the pic below, our hose has the red end — you can see the difference in size between the two.

We ended up finding an adaptor that would work to make everything fit properly.

We made sure to use gas line seal tape around all threaded parts to make sure there would be a tight fit and no leaks.

We ended up replacing both hoses as the other one looked as though it could go at any time. Once we had everything reconnected, we turned the propane on and had no leaks!

I did end up finding the exact hoses we needed with the correct connecting threads, so I ordered a set to have as a backup. You can find them on Amazon here.

Luckily, this turned out to be a fairly easy fix, but this did inspire us to order a few extra things to have on hand for spare parts just in case, like more hot water heater plugs (ours looks like the next time we remove it will be the last time) and some fuses.

A reminder for all RVers: Don’t count out local hardware stores for RV supplies while you’re on the road. As you can see, we couldn’t depend on the usual suspects for parts. Our Ace Hardware has an RV supply aisle that rivals Walmart’s.

After determining we were good to go for our upcoming 2-week trip to Grand Teton, we were able to relax and enjoy an adult bevvie by the fire.
