Thanks Pete and "Phantom" for assisting with clarification!
If the pressure relief part of the valve is subjected to liquid propane
, as soon as it begins to operate to relieve excess pressure it will immediately freeze closed.
I had forgotten about a local incident many years ago. A 250 gallon tank was knocked off the bricks it was sitting on by an earthquake. It rolled upside down shearing the valves off. The sudden release of liquid propane
pressure froze almost instantly on the nearly full tank. Fortunately, the fire personnel were educated about how to handle the situation. They kept the valve area of the tank continually wet with a fire hose. The continual stream of water kept the ice flushed away allowing the propane
in a "controlled" fashion. Since propane is heavier than air it hugs the ground. Care had to be taken to avoid ignition in the immediate vicinity.
All that to justify the statement "don't carry a 10# or 20# propane tank on it's side unless the attached tank base is designed to hold the tank in a horizontal position".
The fuel pickup is fixed and does not float.
Roy, how about a larger more stable base which could be attached with set screws to the smaller tank base?
Sorry about sending everyone into a rabbit chase with the idea about carrying a tank on it's side!!
Thanks to all who contributed to the investigation to avoid an unsafe result!!
