Question 16

I see the flow switch is integrated into the replaceable cell. Can it be repaired without replacing the entire cell? It seems flow switches are the weakest link with Pentair. While I like this system, I'm a little apprehensive. View answer

Question 17

How important to place Core35 after the heater? The heater is about 8 feet from the filter but all the plumbing is underground and the wiring will be a longer distance than desired. This will cause me lots of work on new plumbing. I can easily place it between the filter (pool return) and the heater (which we rarely use in Florida). It this acceptable? View answer
