Fixing an air awning puncture on the go in Caravan Awnings Posted July 24, 2019 · Edited July 24, 2019 by The Penno 41 minutes ago, Fireman Iain said: We’ve an older Outdoor Revolution awning. Does yours have a single inflation point, or several, as ours does? It’s possible that the pressure release valve or dynamic speed valve need tightening in the bladders, there should be a tool in the kit supplied. I had a similar problem with one of our bladders and tightening the valves sorted it. If if you have multiple inflation points, is the same issue affecting them all? Given the heat wave reported in France at the moment, could the PRVs be operating due to the heat, needing reinflation as the weather cools in the evening? Yeah, so I thought the same about the PRV and the heat (its mid 30s here), however I pumped it up last night at about 10pm when the temp was down to mid / high 20s and it had gone limp by the morning - not flat but certainly bowing to the point where I had to duck to get out and pump it up again. This makes me think it's not a temp thing as it was cooler overnight and so in theory should still have been rigid.... So from what i can tell it has 1 inflation point with a PrV on the left hand side - which I've tightened, and on the right hand side it had a deflation point with no PRV from what I can tell. I'll tighten the PRV again tomorrow but dont want to over tighten it!
