I'm investigating more and more into my new to me pool as I find time. I'm considering an automatic chlorinator. I'm thinking with my busy schedule it'll help me from getting behind. To figure out where to place it my reading has determined I need to understand the plumbing better. The heater doesn't work but I believe it's flowing through it still. The easiest place to put it would be before the heater but everything I read says it needs to be after it. There's another little line running that I'm not sure what it is.
I drew the arrows for how I'm assuming it runs.
