The EPS has had about 15% failures. While most companies that sell electronic devices would think this is a very low percentage for failures, it is way more than the ½ of 1% we see with our Cycle Stop Valves. We are just not custom to complaints from our customers. Even though the EPS is a very good device, and I am going to keep a few because I love them on my house and shop wells, we no longer wish to sell them.
I still have the original EPS on my house, which makes it older than any others, and it is still working fine. Even most of the failures we had were installer errors, by breaking off the push buttons or wire connectors. However, we would rather throw the hundreds and hundreds of them we have in the trash, instead of having even one unhappy customer.
If you know anyone who wants to go into the pressure switch business, I would make them a very good deal.
