I am so glad I posted a question on this forum about well pumps. Thank you for taking the time to reply. Very informative. Loved the video. I know what you mean about marketing over efficiency.I always thought if you built a better mousetrap, people would beat a path to your door. I found out marketing is more important than efficiency. If you make a mouse trap so well that it can make mice extinct, the mousetrap industry will try to discredit you and do everything in their power to put you out of business. There is a lot of money in mouse traps, but there is even more in pump systems.
When I approached the pump manufacturers in 1994 with the CSV, claiming it made pumps last longer, which it does, they gave me all kinds of excuses. First it was lead in the valve. Next month I called them and said all CSV's are now low or no lead. Still more excuses. Then just kept procrastinating and saying they were still studying it. Four years later, one of the head engineers retired and called asking to be set up as a rep for the CSV. Said since he no longer worked there, he could now tell me why they would never work with me. Seems I had been blacklisted. A company meeting showed me testing valves in their facility with their engineers. Said test showed this valve would make pumps last longer and use smaller tanks. So, anyone who mentioned a CSV would be fired immediately.
People are so gullible. Like me, no one believes something like that would happen. They don't really have the cure for pump cancer and are just not telling anyone about it, would they? Not only did they not tell anyone, they threatened termination to anyone who did. They also started a dis-information campaign to make people think restricting a pump with a valve is a bad thing. It is so counter intuitive that they don't have to say much to make some people go crazy over it. People fall for their little statements saying it is like "driving a car with one foot on the brake and one one the gas", or like "dragging a ball and chain". But you won't find a single written statement or video from any pump manufacturer saying anything negative about Cycle Stop Valves. It is all hearsay. They pump up their installers at hot dog days and on trips they sponsor and get them to do the dirty work. Like this from a driller or installer which is something we hear everyday.
Right now the tank is nearly useless so I have to act fairly quickly about replacing what's down there. If I can find one of those cycle stop valves I'll be getting a smaller tank. Thanks again for your help.
