Peebhvac; I agree with you about scaring people away from Geo. or Geo getting a bad rap when people read this forum. But 99% of the problem installs on this forum were done by "professionals" , you know like you! If the pros. had engineering degrees most of these problems would not of happened. People that read this forum that are planning a geo install by a pro. or DIY are better prepared to detect a PRO's BS, or to do a better job themselves. If you think Geo. is not a DIY job it tells me all I need to know about your limitations, but do not think everyone has your limitations (and I weld). Gabby great story, if I ever own a big store, you are hired! satleliteman, do not make a deal for beer for Mark, he will drink you into the poor house!
