So my step dad is a captain at our local volunteer fire company. I was telling him yesterday about how I'm venturing into the PCP world, and the cost of things. He took me into the room that they fill their SCBA bottles and showed me 5 bottles that they were about to take out of service (nothing wrong with them, they got a state grant to purchase new ones) He said i could have one and that he could fill it whenever I needed. So, my question is, will this work and what additional valves and or adapters would i need? I'm pretty stoked about not having to buy a bottle and pay for fills, just hope it CAN work.
