Hello, I have the Air Rail 1.5 air mattress. I noticed over time the valve was becoming harder to lock, and after my most recent use I could no longer lock it. I can push the valve downwards, but it does not rotate into the locked position. Is there any method to repair this myself? Or to replace the valve? I am no longer living in the US, so I cannot take it into an REI store. thank you!
