I thought this might be interesting to some people. Cycle Stop Valves, Inc. is a small company. I still test nearly every CSV myself. The picture below is the batch I tested this morning. This is our busy time of year, and we will send out this many CSV's nearly every day, and have been doing so since 1993. The quantity is much less in the winter months. But we still average 20,000 to 30,000 valves a year. This is where I get my experience. Working with 30,000 water systems a year I get to see a lot of things that people who only install a couple hundred a year never get to see in their lifetime. And most of those 30,000 systems a year we see are problem systems, where the pump, tank, or other parts of the system did not last very long. So not only do we get the experience from 30,000 systems a year, but we get the experience of all the worst cases. These are the cases where a big pressure tank or three did not solve the problem. We also use CSV's to replace many, many VFD's every year, after the homeowner gets tired of all the problems with VFD, and starts looking for an alternative. Many people also install CSV's to solve water hammer problems, or just to get stronger pressure for showers or sprinklers. Frequent failures with check valves, pressures switches, relays, and other things are also reasons people use Cycle Stop Valves.
