I was wondering if anyone had a demand valve rig. I have a few questions for them about the requirements. A demand system would probably same on the amount of O2 being used. Am I correct in assuming that if you aren't breathing in, it sends nothing? Unlike the traditional system that has gas flowing out whether you're breathing it or not.
I love my tank. It is green and gorgeous. It is cold, and warming at the same time. I think I am in love with my oxygen. Is that abnormal? I just wish I had a smaller rig I could take with me on excursions away from the domicile.
