I am working with Pool Power (the efficiency people) on the bid right now and they have several customers who are willing to talk and let me see their systems. It may be a couple of weeks, but I can update the posts with the information I find out.

Just talking to the engineer, who is a long-time certified plumber, from Pool Power, he says that they have been installing the Ikeric for 4 years and have never had a service call on those pumps. They are able to use the flow switch(es?) in tandem with the solar system to get enough flow to fill the solar and then ratchet back the flow to just enough so that the solar system is not kept under pressure.

The Ikeric has a Sta-rite max-e-glas pump body. All the seals etc are readily available at any local pool supply. Ease of servicing was a concern of mine with going with the Ikeric, but knowing this is very helpful.
