Variable speed pumps and cycle control valves

There has been a lot of discussion revolving around these two products lately with a lot of misinformation on both sides of the fence. The following link is from the Amtrol Company. They make well tanks and such. I suppose one might argue that they have a horse in the race as such but with either system you still need a tank of some kind so I really can't see where they would be biased. They took the time to do the research and run the tests. If you have any questions about these two products and what they do then by all means read on.
