Kind of cool but it's not UV reactive so it wouldn't work for me. ;->

I was amazed they didn't blow tubes off the fittings after they got it going and cranked it to full throttle. It makes me feel much better about my loop. It would have been cool if they measured how many gallons per minute they were pushing.
