Winterize Manufacturing - RV Blow Out Plug
I finally found this little ingenious adapter to blow out the water lines in our DWR Airstream to prevent the lines from freezing in the winter. I looked all over, but I could only find hose adapters that were clunky and expensive.
I was able to blow out the whole system, including the water pump, with an air compressor attached to my city water intake on the Airstream trailer in less than an hour without having to run in and out of the trailer non-stop. I’m so happy too have found this little, blue, nicely-machined gem. It is made by Winterize Manufacturing and costs$17.95.
