Propane leaks during storage.
Is it normal to have to bleed air from the system when you get your rig out of storage? I do shut the propane off when I drop the trailer off for storage. And I always considered it normal to have to...

I’ll give yet another explanation. Electronic valves do not seal 100%, and they are all basically one way valves, offering no resistance backwards. LP gas is very temperature sensitive- the lp that remains in the lines at atmospheric pressure after they have leaked down will expand and contract with ambient temperature, it gets cold, and the pressure in the line is below atmospheric,,drawing in air to the system.
Let me ask you this. The LP in the line is at pressure. It slowly leaks OUT due to pressure pushing it out. Does it not seem logical, that at some point after leaking down the in line pressure and the atmospheric pressure will be equal? The existing LP vapor left cannot exit OUT because there is no excess pressure to overcome the outside air. So, you reach a stand off. This is how I look at it. Doug
