OK so I did a crude drawing by memory in Google keep. I am not at pool location now but will be in mid July. The heatpump needs to move a couple of feet or so to get more top airflow with a newly constructed deck. It has never had a bypass in its entire 10 year life when installed with new pool. Technically it is not necessary according to the manufacturer (heat siphon) as it is titanium and impervious to any chemical damage as well it is a 100% flow through design. However since we need to move it and reconfigure a few things anyway I'm going to put in some sort of bypass. It is only used at most 2 months of the year due to the climate in Vallarta.
Any thoughts and input would be really appreciated as this is our first pool and I am still getting my head around it.pool #1.jpg
