Blast from the past 1994

Laughing at myself for how old I have gotten in the last 30 years. This was our first video from 1994. The CSV models have changed over the years but everything I said back then is still true and the pumps we set up to test Cycle Stop Valves are still working today. So, the tests continue. Just how long will pumps last when controlled with a CSV? I may not live long enough to finish the tests. Lol!
