I was wondering if you had any experience with either the Well Manager or Herculian Consta Boost systems by Reid Plumbin Products? It seems that they have a complete system for low flow or low yield wells that takes care of low or no flow water situations and at the same time uses a CSV to maintain constant house pressure.

I currently have a low flow well <2.5 gallons per minute and have a somewhat unused poly storage tank that is misconfigured for our needs. This application appears to be in line with some of the suggestions I have found on your site in using a submersible pump inside the cistern. The torque question seems to be answered with the tank that they offer. Your thoughts?
