Make sure that your concentrators are putting out the same psi before you hook them together with just tubing and a splitter. If one is putting out significantly more psi than the other, there can be so much pressure in the line that the weaker concentrator will not be able to push its oxygen into the line, creating a backpressure situation for itself causing it to alarm and shut down. Even if that pressure is relieved, the higher pressure machine can still push its oxygen upstream of the weaker concentrator and cause a similar backpressure effect.
