''Don't forget your dump valve though'' Hmm...totally ignored that

I could place one on the regulator inlet, but that will be difficult to operate from outside (as per FRA regs.).
Having said that I probably wont need it as its not listed in these regulations where the competition will take place:

Will try to think of how it could get incorporated into the system anyway - can someone please post a pic or link of a similar valve just to get an idea, thanks
