I've been lurking here for several months, gleaning as much information as possible. Planning to go the TFP route, as I've seen my FIL go through all kinds of hassles with his methods. PB is to begin digging next week. Planned specs are in my signature. Wife is really wanting to add a heat pump/chiller to the install to be able to get some use this year and extend future seasons. We may swap to a full Jandy system as well; nothing like last minute changes. I will try to update this thread with pics as we proceed. All input is welcome.
