[RE-wrenches] Pump choice - Grundfos or Lorentz; distributers of Lorentz

[Windy Dankoff]

Bob,

Warren is referring to problems with Lorentz that showed up 5-7 years  
ago. There was a problem with rubber that occurred only in some kinds  
of water. It took a long time to track down. It was solved and  
reliability has been high ever since. That's what I've heard from  
several sources.

I would consider both Lorentz and Grundfos -- look at total system  
cost of both and make your choice from there. You'll also see that the  
control options are different, so consider those too if the decision  
is a close one.
