Quick question - when a pressure relief valve operates, I've always assumed that it vents excess air to relieve pressure, and then reseals/stops venting - is that right?
When I went to the RIB today in the club compound - one tube compartment is flat, with the entire centre of the pressure relief valve missing.
Current thinking is that it's either:
1) malfunctioned and blown itself out completely, or
2) somebody's nicked it...
I suspect 2 - as I can't find it in the boat (or anywhere around it).
