I just recently bought all new equipment for my pool that came with the home I purchased about a year ago. I have a contracter resurfacing my fiberglass pool and he said that he would install all of the pool plumbing for me (my filter, pump, SWG, and solar heater). I don't have a picture of it but I made up a quick diagram of what it looks like.
The thing that is bugging me is when the water comes out of the filter, there is a 3-Way valve that allows me to turn off the water going to the solar and go straight through the SWG and back into the pool. But When I would turn the 3-way valve to go into the solar heaters, I would think it would totally bypass the SWG?? When I asked the contractor this question he informed me that when the 3-way valve is turned to go out to the solar heaters, I will still have water going through my SWG. He said that it will open up all valves so the water will flow through everything. I want to belive him, but in my head it still doesnt make any sense. Can someone please give me their opinion before this drives me crazy HaHa
