Not cold feet, just TMI that nobody cares about. It is depressing to have the proven cure for pump cancer while others in the industry try to make everybody think it is Snake Oil. It is depressing to try to help people make their pump systems work better and last longer while others in the industry are fighting to keep pump systems in the stone age. It is depressing to have people steal your patents and ideas. It is depressing that there is a group on a pump forum trying to keep people from finding out how to save money on their pump systems. It is depressing to sell a product that is disruptive to the pump industry the same way the refrigerator was disruptive to the icehouse industry, and have others in the industry hate you for having a product that works too good. It is depressing to have a 20 year old product that has been proven successful hundreds of thousands of times, and still have people question if (sorta close) copies wouldnt be just as good. It is depressing that there are places on the Internet (Ripoffreport) where people can lie all they want and hide behind anonymity. It is depressing that people in my profession (well drilling and pumps) are so mistrusted because many act like they know what they are talking about but dont, or are just plain crooks.
It is a good thing I am hardheaded and thick skinned. I am determined to let everyone know the earth is round and not flat, as others in the industry would have you believe.
This link will give you a description of how the CSV differs from the copycats.

PS; I will still be glad to help DIYers even if you disallow advertising, but I know others will not.
