I am new to pools and new to forums, so please excuse my ignorance.
I have attached a picture of my pump room where I think there is something wrong with the design of the plumbing.
I have a 3 way valve after the pump so only part of the flow will go through the filter/ heat exchanger loop.
I can't get enough flow or pressure through this loop to even activate the flow switch. Is this whole design wrong or is there just that much loss through the exchanger?
