The following is a letter from a Pump Installer in Colorado.
Dear Mr. Austin,
I've met you several times at the Mountain States Groundwater Show. I have used several different VFD's instead of using your valve thinking that it would be a better system. After seeing the prices of these systems rise from 3-5% every year for the last five years I started feeling very guilty selling little 3" pumps for thousands of dollars that probably won't last any longer than what I was selling and went back to using the Cycle Stop Valve. I always thought that putting back pressure on a pump would hurt it as much as turning a motor very fast. But after reading your website I have to make a big apology. I should have been using your system all along. I've had less call backs on systems where I've used Cycle Stop Valves they are more reliable than any VFD. I'm making a lot more money than I was with the VFD's also. My customers ask me how can you beat your competitors price by $1,000.00 or more. I just laugh and have to educate them about your product versus the big manufacturers. I hope to see you in Laughlin this year and you've made a customer for life. I'm done with expensive VFDs. Cycle Stops are all I will use.
Thank You,
