Awesome. In a past life, I installed helium stations in party stores for inflating balloons. By the time we finished doing all the stores we had a pretty good system in place. We put a three tank manifold in the back store room and then ran tubing to 4 nozzles built into the counters in the front of the stores. With the manifold, you could just turn off a tank when empty and turn on a full tank and switch out tanks without disrupting supply to the front. Yeah overkill...but fun.
