Review on DGZZI Straight Connect Reverse Osmosis by Marc Stewart

I haven't tried the high pressure test and it was only in place for a day, but because it's so easy to apply and remove I tried both while I could watch the flow . In fact, it was only a possibility. I was a little apprehensive trying to blow air and couldn't get it through anyway, but it worked properly when plugged in and didn't seem to block water flow in the right direction. It has locking tabs that prevent accidental detachment of the hose. At that time it never occurred to me to test it with air and a piece of hose.
