I was asked a question today that I need a definitive answer on with documentation to support, Please!
A friend picked up a tank today from his LDS that was sent out for Hydro and VIP done 'in-house'. The tank was then filled with air and then taken home. A regulator was put on the tank and the tank valve was opened. Air immediately began leaking from the tank valve under handle/knob. It was discovered that the valve nut retaining the teflon washer was loose. Once tightened, it worked fine. The shop claims it wasn't like that when the filled the tank...and my friend only attached the stage 1 and opened the valve.
1) So how does this happen and how did the shop fill it without recognizing it? It leaked like a sieve.
2) Should the person doing the VIP remove the old stickers and NITROX labels since the tank was converted to air?
3) Should the VIP include checking o-rings on the tank valve?
3) Can someone that is NOT 'certified' to do VIPs do them under ANY circumstances? ie. under someone else's 'certification'? - even when the 'certification' holder is not on the premises...
Many thanks for your answers - again please point me to the documentation also.
