I do not have any one way valves on my system. I'm in CA so I don't have a humidity problem. Back pressure is really bad for the units, avoid it at all costs and keep the O2 valve always wide open. If you have trouble just regulating your flame with the gas valve because of too much O2 flow, add another bleed valve somewhere on the line to reduce the flow to the torch without reducing the outflow from the concentrators.
