Thanks for the feedback on the EPS15/99 pressure switch. I understand your concerns about the digital properties compared to the old mechanical switch. We have been testing and redesigning this switch for about three years. We went through several prototypes that did not pass the smoke test. The latest design has withstood hundreds of thousands of cycles while working under a heat lamp. This accelerated test put more than 10 years worth of abuse on the switch, after which I installed the very same switch at my own house, and several others in places where I can keep an eye on them.
If there is one thing I know, it is what destroys pumps or pump system components. I was able to make several of the first prototypes fail in short order. I won’t say the new EPS15/99 is completely bullet proof, but it withstood all of my accelerated tests. Any component has to be fairly robust to stand up to my accelerated testing.
The people who work at Cycle Stop Valves are now confident enough that we have installed the EPS15/99 on our own homes, and even on the pump at the CSV factory. We are offering a two year warranty, which is pretty good for any electronic component.
We get ask how to set a pressure switch many times a day. Many people are afraid to try adjusting a mechanical pressure switch. And you would be surprised how many pump installers do not know how to set a pressure switch. Many times they will purchase a new 40/60 switch, because they don’t know how to turn up a perfectly good 30/50.
So the EPS15/99 has push button adjustments. You set the mode to Lo and push the up or down arrow until it reads 40. Then you set the mode to Hi and push the up or down arrow until it reads 60, and you are done. No more guess work.
The enclosed relay and gasket sealed enclosure also prevents problems with fire ants. Fire ants have become a real problem for switch contacts in the south, and they are continually moving farther north.
Low pressure cut off, voltage protection, and rapid cycle alarm are features that come standard on the EPS15/99.
The old style FSG2 has become less dependable over the years. The points are smaller and the plastic point retainer is not nearly as reliable as the old fiberboard style. The diaphragms also tend to leak much more often that they use to. Many people now say that some of the knockoffs are actually better than the original FSG2.
The EPS15/99 is a little more expensive than the FSG2. However, it is less expensive than many of the higher end switches such as the Allen Bradley or Mercoid. Being able to digitally set the bandwidth to as little as 10 PSI makes the EPS15/99 work very well on large pump systems or systems with multiple pumps.
The EPS15/99 is Cycle Stop Valves, Inc. way of giving the customers what they want, which is a pressure switch with easy push button adjustment, easy readable display, and keeps the fire ants out.
