DaveSamsell Posted August 30, 2020 Share Posted August 30, 2020 In one of my aquariums, I noticed the bubble air-flow has been decreasing over the past few days, but didn't give it much thought. Well, just now, it stopped completely. I thought it might be the USB nano air pump or power supply. Wrong on both counts. The problem was with the check valve. Wasn't sure if it was from the back pressure or what, but the check valve component halves were loose & with a little pull they came apart. Simple fix, just screwed the halves back together and back in business. They were tight, when I originally put the check valve into service several months ago. Will keep an eye on it for a while. 1 Link to comment Share on other sites More sharing options...
